Tissue Culture Microscope
One of the most important uses of deionised water is in the laboratory. May it be a chemical, microbiological, genetics and molecular biology, medical or Tissue Culture laboratory, water is an indispensable item inside the lab.
These are areas of science which call for the one of purest form of water available known as deionised water.
The process involved in deionising water is long and painstaking, ensuring that the end product is uncontaminated and free from impurities. It undergoes a five step process of filtration: organic trap, twin bed deionizer, mixed bed resin, Ultra Violet treatment, and filtration through a 0.02 micrometer pore size.
Organic impurities are filtered out first then the ions (cations and anions) are removed. At this point, water is deionised. However, there are still other impurities found in water and so water is subjected to an ultraviolet treatment to kill microorganisms. Another filtration through a mixed bed resin is used to remove any remaining impurities. Finally, water is filtered using a filter of a 0.02 pore size.
The end product is ideal for use in the laboratory wherein every single item must be in their purest form to come up with accurate results.
In the chemistry laboratory, it is used in preparing glass wares, utensils, and other tools. Normal or tap water usually has impurities present, such as fluorine and chlorine, which can influence the results of your chemistry experiments.
Deionised water is used to rinse glass wares, laboratory tools, as well as small and large apparatus used in the microbiological testing. It is also used as a solvent in media preparation and other microbiological procedures requiring water. Everything must be sterile inside the microbiology lab and every process must be done asceptically.
In a molecular biology lab, deionised water needs to undergo further filtration to be DNase or RNase-free to be deemed usable in this setting. Molecular biology and genetic experiments are particularly sensitive to impurities because of the need for an accurate and exact set of results. The standard error must be very slim indeed.
The same goes for a tissue culture laboratory, everything must be sterile and the processes must be asceptic. Deionised water is also used in media preparation as well as in the set-up of the needed items and equipment.
A medical laboratory processes clinical specimen of patients to obtain more information on his/her health. The physician can then make a better evaluation of the patient's health based on the results of a urine sample or a blood sample, for instance. Therefore, careful handling and preparation of the samples and the whole test are performed to ensure that the results are accurate. The proper diagnosis of a patient's health condition lay heavily on the results these tests will show.
Deionised water, however, must meet the standards for each type of laboratory since each also has a different need. Nonetheless, deionised water is already of a higher grade than tap water and it can be used for various laboratory preparations and procedures.
Aside from its crucial uses in the laboratory setting, deionised water is also used extensively in the food processing, pharmaceutical, cosmetics, electronics, and automotive industries. It has even found its use into your local carwash. Water is indeed a central ingredient in everything we do.

science reasearch culture, tissue samples?
Is there a place that sells living samples in petri dishes of human diseases such as cancer cells. I would like to view them under a microscope and try to find ways to destroy them. I am not a scientist or researcher. This is just something that interests me.
Thank You
ATCC is the main place researchers=scientists go when they purchase cell lines for most diseases. The people who generate new lines, such as cancer cell lines etc., will most likely donate them to this repository for all researchers to use. It costs money, from $250-500, for each cell line. If you are truly interested volunteer in a Research Lab, the reason for this is related to money. Most labs are always glad to get interested people to join them, even with no background in biology or science. This is the level where most scientists start out there career in college anyways.
Biology is extraordinarily expensive! Let's start with getting your lab up and running. The incubators, refridgerators, tissue culture hoods, and everything else you would need (all sterile) for only cell-culture run around $15,000 if you are good at negotiating. This does not include utilities, or set-up (air-filtration system, biohazard disposal etc.) for any of these large products ( 8ft tall, 8ft wide, 3ft deep, and up to 1,000lbs) and is just for Cell Culture. The running cost each month would be well over a thousand dollars. Next comes a good scope, easily $20,000 for a good disecting scope. Want fluorescent filters and a laser to do any kind of histology, up it to $50,000. Digital Camera? Add another few thousand. You need a computer to visualize your data, get a G5=$2,000+. Any real cell biology or molecular biology, another $5,000-$10,000 for reagents and some micropipets. Tack on about $2,000 for running monthly expenses as most things like pipet tips you cannot reuse and must be sterile. Centrifuges? You will need them for anything with molecular biology, another couple thousand dollars. You will need flammable storage and hazardous waste disposal method, plus a Fume Hood for some of this stuff. Add $5,000. Remember none of this includes powering all this crap 24/7.

Eustachian Tube Dysfunction Tinnitus - Rhythmic Humming in the Ear
Eustachian Tube Dysfunction Tinnitus
One of the many unusual sounds a person can right here are tinnitus sounds. These are extremely annoying, and what's worse is which there are several types of ringing in the ears - or tinnitus. One type involves noise being created inside the ear in a rhythmic fashion, like a heartbeat. Eustachian Tube Dysfunction Tinnitus
This is called pulsating tinnitus (or pulsatile tinnitus). With this, a occupant experiences sensations in the ear that have the same tempo as a heartbeat. Pulsating tinnitus is widely considered a very uncommon type of sensation in the ear the current is lead to by blood gentle in veins and arteries and other smaller vessels in the neck, skull, and ear. While the performs not occur that often, it can often be a symptom of more dangerous ailments and has to be examined by a doctor immediately. If you have these kinds of symptoms or experience experienced this, go see a doctor without delay.
Common causes of tinnitus include hypertension, globe-shaped tumors, heart murmur, abrupt changes in blood flow in arteries and veins. Another major reason is also Eustachian tube disorder. If this worries you, protect yourself now by reading the facts given below -
• Chronic infection and irritated tissue in the middle ear is linked to tinnitus in rhythm with the heartbeat. This always coincides with an increased bloodflow to the ear tissue. Eustachian Tube Dysfunction Tinnitus
• Eustachian tube dysfunction leads to pulsating tinnitus, and is caused when tubes open and close as one chews, swallows, yawns, or speaks. But due to many reasons, like sinuses, colds, coughing, allergies and excessive earwax, these tubes become blocked. This stresses the eardrum and leads to tinnitus that goes along with your heartbeart. This is very aggravating, as you can imagine!
• Discharge in the middle ear is another frequent cause of tinnitus. Diffusion of liquid in the middle ear is frequently caused by inflammation and infection in this part of the hearing system inside the human ear.
• Humming can also be caused by abrupt changes in veins. A change in your physical well-being can lead to this alteration in your arteries and veins in your neck, skull, and vessels. The veins in question are called jugular veins - which transmit blood from the brain to the heart. If alteration affects these veins, ringing problems in the ear can result. These conditions frequently occur during pregnancy. Pulsating tinnitus may be uncommon, but it can be treated effectively. Eustachian Tube Dysfunction Tinnitus
This condition often pops up as a chronic symptom, so medical attention should be sought as soon as possible. If you ignore it, pulsating tinnitus doesn't go away on its own. Therefore it is crucial that you seek medical attention right away before it gets worse. Suffering from Tinnitus and Ringing in Ear? Get your life back forever by checking out Eustachian Tube Dysfunction Tinnitus now.

How do you connect this macro ring/exstention tube to my Nikon D60!!!!!! (link provided)?
http://www.amazon.co.uk/MACRO-EXTENSION-TUBES-NIKON-Adaptor/dp/B001CWVHTI
please, tell me how, very simply, because no matter how much light i use, its very very dark
most of the time it says lens not attached
and most of the time the lens just attaches upside down ffs. what the hell, i didnt come with bloody instructions 
i will very much love anyone who helps me out here.
One of the drawbacks of buying extension tubes rather than a macro lens is loss of light.
As to it saying the lens is not attached: even on the Amazon listing it quite clearly tells you that "There is NO electronic connection between the body and the lens".
I bought the more expensive Kenko extension tubes and they DO let the lens and camera communicate - yours don't.

Mobile Heating Unit
Jun/100
Mobile Heating Unit
With the UK's weather arguably more unpredictable than ever, heating and ventilation products are in huge demand, offering an effective way to cope with the changeable climate. However, with the price of fuel having rocketed during the past year, this can be expensive, making it increasingly important to ensure the most efficient products are used to achieve savings, where possible.
High Demand For Heating & Ventilation Products
With one day often drastically different to the next we are continually turning to heating and cooling products to ensure indoor and outdoor comfort amid the changeable climate. As a result, demand for heating and ventilation products has increased dramatically over the last few years resulting in an explosion of new products. It has been estimated that the non-domestic sector will benefit from continued growth of around 3-4 per cent until up until 2010.
Renewable Solutions Offer Energy & Cost Efficiency
However, the combined impact of government regulations and directives, soaring gas and electricity prices, and increased budget constraints for the public sector, mean careful consideration must be given to the specification of these products. It is increasingly important to look past the initial outlay required when investing in the newest renewable solutions in order to achieve both energy and cost efficiency.
Many manufacturers have developed highly advanced and intelligent heating and cooling products which can help to achieve this dual aim of reducing energy and cutting costs.
Air Source Heat Pumps
One such solution is heat pump technology and one of the most popular types is the air source heat pump. An air source heat pump uses the outside air as a heat source or heat sink to heat or cool an interior space. Often favoured for their flexibility and compactness, these pumps are generally sited outside of a property and can be floor or wall mounted, without the need for any extensive installation preparation, and are similar in the size to an air conditioning unit. Used to warm water for radiators or underfloor heating systems, or to warm the air in the indoor environment, these systems utilise approximately 25-35 per cent of the electricity of a standard electrically heating system for the same amount of heating, significantly reducing utility bills.
Ground Source Heat Pumps
Conversely popular, ground source heat pumps can also be used to power radiators or underfloor heating. These systems employ pipes buried outside a building to extract heat from the ground, where the temperature is constant, meaning it can be used throughout the year - even in the middle of winter. Used widely in school applications where they can be easily located under the playground surface, these systems can not only make a huge contribution to reducing carbon emissions but also cut payback periods by 35-40 per cent through fuel savings.
Low Wattage Products
The public sector can also benefit from making more energy efficient ventilation choices. Low Wattage products such as low wattage fan heaters are especially popular, as apart from efficiently improving the indoor environment, they also offer up to 80 per cent energy savings - a Welcome additional benefit with soaring energy bills looking set to stay.
Heat Recovery Systems
Another method of improving energy efficiency is to consider using the 'waste' heat produced by a heat recovery system. Growing in popularity, heat recovery systems extract air from within the various rooms of a building through a Heat Exchanger with the most common use being space heating. The system then supplies fresh air through the same heat exchanger with up to 95 per cent of the heat, which would be otherwise lost, being transferred. As a result, the air is carefully filtered and condensation eliminated, greatly improving the quality of the indoor environment while minimising energy costs and reducing greenhouse emissions.
As the dual issues of sustainability and cost continue to dominate the public sector, authorities can no longer afford to simply go for the cheapest heating or cooling solution, as this is not necessarily the most cost effective or energy efficient method. The changeable weather patterns we regularly experience shows no sign of stopping, so it is important to make the most of the newest cooling and heating solutions available, so as to prevent energy from being wasted and energy bills increasing unnecessarily.
Newey & Eyre is one of the UK's leading electrical wholesalers with a network of over 150 branches providing electrical supplies for the trade. HVAC products include heated towel rails, Fan Heaters, water heating products and heating controls. For more information and to order online visit http://www.neweysonline.co.uk
Chemical Smell From Central Air/Heat Unit?
I have a chemical smell coming from the air/heat vents in my mobile home. The central unit was installed this past summer.
It was checked recently, and I was told there was water (or liquid) in the duct work...I don't know where the water came from as I haven't had any leaks. Any idea where the chemical smell may be coming from? It comes and goes, though sometimes is worse than others. Sometimes it is so strong it makes me sick on my stomach. Any suggestions? I didn't have this problem with the old unit. I only had it replaced to install a heat pump rather than the split system that was in my home. Thanks in advance.
+ both of the other answers are great and you should do them, but in addition (and this is pretty easy) buy a small box of Arm and Hammer baking powder and dust your input and output filters with it. It should clean the air and make your place smell fresher. Then place the box in your fridge to make that smell good and save it there until you need it again in about 6 months when you should be changing your filters anyway.

Waterproof digital cameras 7 Choice You Can Chose
Digital cameras are risky to use in water, as they will malfunction. This deprives those who love diving and spending time in water, the pleasure of taking photographs underwater as well as around water (in the fear that the camera might fall into water and malfunction). Therefore, waterproof digital cameras also called underwater cameras, provide a chance to photograph the underwater world which would have been otherwise inaccessible with normal digital cameras.
The following is a list of some waterproof digital cameras that are commonly used for underwater photography.
The first one of waterproof digital cameras reviewed is Sea and Sea DX-1 G Compact Digital 10.0 MP camera with underwater housing set. This waterproof digital camera has ten megapixels (which is pretty good photo quality), a polycarbonate underwater housing (which makes it waterproof) and a ‘sea and sea’ mode which optimizes digital photography under water. It also has some other features that are advanced, such as manual control over exposure and focus, an extra flash light and the camera also has the ability to shoot videos.
Intevac IC700 7.0 MP Digital Camera with Underwater housing falls under waterproof digital cameras, which provides a pretty good image quality (with seven megapixels) and is affordable as it is under the $300 price range. It is considered a good waterproof camera and is rated for underwater photography to a depth of 180 feet. To emphasize this opinion, the camera comes with features such as macro mode with a built in flash which can reach up to about five feet when underwater.
Olympus SW series may be the best well rounded waterproof camera at the moment. This camera completed with 10 Megapixels, ISO1600, and a 3.6x optical zoom feature and you could diving with this camera as depth as 6.6 feet.
Pentax Optio W30 is another waterproof digital camera design you should consider. Released with 7MP - ISO1600 and 3x optical zoom image recording feature, Optio W30 supported with both SD and SDHC, videos in this model is of 640x480 in MOV QuickTime MJPEG format.
Another one of waterproof digital cameras is Sealife SL320 Reef Master Mini underwater digital camera. Weighing about eight ounces, and being a compact camera, this is very useful for those who want a light weight, easy to use waterproof digital camera. The camera has underwater exposure and sea modes and has six megapixels. The shutter speed of this camera is within a range of 1/60th to 1/1000th of a second. This waterproof digital camera has a rating of 130 feet depth for underwater photography.
With an underwater photography rating of 50 feet depth, VuPoint DC-WPC-ST531TBLK-VP Underwater digital camera is another recommended waterproof digital camera. It has five megapixels and also has video capturing ability. It features digital zooming and has the ability to shoot in macro settings and control aperture settings. Also, it is less expensive compared to other waterproof digital cameras.
One of the best designed waterproof digital camera for up to 5feet depth of water is Sanyo Xacti VPC-E1. With 4GB memory card, and MPEG-4 AVC/H.264 at 640x480 powers, the Xacti E1 could work with an approximate record time over 5 hours. This small and easy to handle Video Camera also offers a solid 5x optical zoom with a 6MP CCD at up to ISO1600 power for still images, so beside video you can also take a pictures every moment. With flip out view screen and special key feature of this Video Digital camera will saves you from the risk of bumping in underwater objects while diving around.
By choosing wisely from the wide range of good waterproof digital cameras available in today’s market, you can chose a good quality waterproof digital camera at an affordable price, to make the next underwater experience – an unforgettable one.

Is there a decent Digital Video/Still Camera combo?
I would like a digital camera and digital video camera that I could have combined so I dont have to carry around 2 things. Anyone know of anything like this?
Nearly all camcorders available now will have the ability to take Digital Still JPEG images. The tricky part is determining quality. If you just want to share your images online (Facebook, Photobucket, etc.) then any camcorder should be fine.
Most camcorders do not have the same features for taking stills that a traditional Digital Still Camera will have. The majority of MiniDV camcorders I've seen take 1 Megapixel stills as opposed to the 8 to 10 Megapixel stills of common digital cameras. Even the newer High Definition camcorders take stills commonly around the 3 Megapixel range.
You get more if you pay more, which normally doesn't matter to the common camera user. If you're doing professional work with your still photos you would probably want to stick with a separate digital camera and camcorder.
If you are just taking photos to share with some friends it makes perfect sense to get a camcorder which can take good video but also take the stills you want to share. In this case, most any camcorder should suit your need.
Good luck!

Guidance Towards Surveillance by Spy Cams
The expansion of knowledge and the developments of new innovative equipments are improving to prerequisite to introduce the hidden cameras, the spy cams, the nanny cams and many more cameras on scientific basis. Lack of proper equipments for a smooth flow of life was an issue in the past. But today there are so many latest equipments especially designed and planned for our comforts but the only matter is we have to make good use of them. Earlier when there were no equipments like the concealed cameras, it was not easy for the authorities too to analysis the disobedience and harm which the culprits were creating at the public places. Even at the work places or different business firms, it was difficult for one man to manage and control the nuisance which could create disturbance at their work place. But now, under these circumstances it is advisable to encourage and install the concealed cameras at various public and personal places to avoid all the problems and safe guard our selves and the natives of the particular place where we feel that disturbances may take place. For example, the authorities can install the big CCTV cameras for the surveillance of the culprits at various public places like the shopping malls, the auditoriums, the multiplex theaters, the railway stations, the air ports for the safety of the people and the businesses can install the small spy cams or the concealed cameras at their work place for their own security. Even the spy cams can be installed at homes for the surveillance of the actions and movements which take place in the surroundings of the apartments of particular housing society.
Nowadays in almost every part of the world, the builders of various housing societies are on their way to introduce and install the various types of concealed cameras during the construction of the building itself for the safety of the people who are buying or booking the flats with them. Both wired and wireless solutions and equipments can be installed in new construction as well as in the existing homes giving any homeowner the power to be green and safe because security includes controlling access and surveillance. These concealed cameras help to regulate and analysis people going in and out and monitors who goes where and when with an identification device, which identifies a person by his unique biometric traits or by reading a unique card associated with an individual. In case of the break in, the access control even allows the authorized person to come in, till the concerned authority studies the situation of the environment, so that the evidence is not tampered with. Surveillance helps in monitoring the movements within and outside the building and its periphery through the CCTV camera or perimeter devices like the intrusion alarms. These equipments also help in alerting the security, in case of violation of pre-set norms. These equipments or rather the CCTV cameras or the concealed cameras are not very expensive or beyond the reach of the common man. There are varieties of cameras which are affordable. You can log on to any of the leading websites and get all the necessary information.
