Why does water expand when it freezes?
As water freezes the molecules it is made from become a rigid framework. Think of it like scaffolding poles. they take up a lot less space when the are all in a pile but they take up a lot more space when you bolt them together.

Which Is The Best Laboratory Chain For Conducting Tests And Analyses?
Choosing the right laboratory for conducting various tests and analyses can be a tricky affair. If there is any discrepancy in readings, it can be cause quote a stir. Thus, it is imperative that the staff operating the equipment of the laboratory must be expertly trained. The equipment itself must be top notch in quality. LiveScanLabs has managed to meet all this criteria. They have centers in
Hialeah,
Hollywood,
Fort Lauderdale,
Pembroke Park and
Pembroke Pines. They conduct
Fingerprint Analysis,
Fingerprint Testing,
**** Analysis,
**** Testing,
DNA Analysis,
DNA Testing and regular health tests as well. Visit their website at

Heraeus pico biofuge
Are you sure that the lid safety interlock switch isn't damaged/dirty? If the centrifuge can't detect that the lid is closed it will never start. Sometime it just needs an extra push down on the lid.

Premiere MS01u microscope bulb flickers. Won't come on.
It sounds like either the bulb is loose or the connection between the bulb socket and a wire is loose. To check both, Loosen the screw knob on the underside of microscope and open the panel to expose the bulb. Use a small screwdriver to loosen the screws holding (the two screws closest to the bulb) the prongs of the halogen bulb. Note that the prongs of the bulb are held in place by small brass plates which shift slightly when the screws are loosened. Remove the old bulb. Important: Do not touch the new halogen bulb with bare hands. Wear gloves or hold the bulb using tissue or lens paper. Body oils may damage the halogen bulb. Insert prongs of replacement bulb into top of socket (above the brass plate) and tighten screws slightly. (The brass plates will move up to hold the prongs in place.) Close door and hand tighten the thumbscrew knob.
If this does not work, contact Premier for assistance: Premiere® Microscope Service, 7241 Gabe Court, Manassas, VA 20109 (703) 330-1413

Hello,
does anyone recognize E61 error code for Euronda E9 autoclave please?
The error E61 indicates that your water pump has failed or is not active. You should check the pump and replace it if needed. You should also check the steam generator sensor and replace it if needed.
For more information, contact Euronda at Water inlet pump inactive or call (+39) 0445 329811 (Vicenza, Italy)

MS-01U Parts
If this is a microscope, the part you are referring to is the stage control. You can get the part from C&A Scientific at http://www.cnascientific.com or by calling 703.330.1413

Can I put a 40x microscope lens into an ultrasonic
Soak in a product like lime away first. Glass lenses cant warp without heat. Plastic even crystal type can absorb minerals. Ultrasonic can help clean all of them. The lime away will remove almost all trace minerals, lye or powdered drain cleaner will remove organics. Gool luck let me know how these ideas woek for you.

I have inherited a Nikon
I think the number you gave is the microscope serial number, to hope to get help you need to find the model number so people can help. At least post a picture. In general the microscope needs a light source to be bright enough to use. The transformer is meant to provide power to the light. If you use the microscope with a light shining through the object held by a glass slide then the light is below the stage which holds the object. Sometimes on simpler microscopes they have a mirror below the stage and you shine a bright light beam into the mirror and must adjust the angle to reflect the light through the slide. In more complex systems the light is built into the microscope. For opaque objects you must shine the light from above onto the object. If you can't find the official Nikon light source to connect to the transformer, you may be able to get non Nikon light sources. For my stereo microscope for example, I use a LED ring-light I bought on ebay for ~$25. This lights the objects from above and fits around the microscope tube just above the stage.

How will you track a moving image in the microscope?
Your question is hard to answer without more detail, including movement rate and required magnification. For relatively slow moving objects you can use a movable stage (X-Y stepper motors tied to a computer). Usually the direction of motion is erratic or unknown, and some digital tracking software will have to be written to drive the steppers so as to follow the designated object of interest. This may be something you have to develop yourself, although there may be some "tracking" software commercially available (or adaptable).
Note that you usually cannot take a video of the object as you track it, due to the quantum action of the stepper motors. However, this does not keep you from taking a series of stills (step - capture - step - capture - step ... etc.) and turning them back into a stop-action video. There are a lot of free or cheap programs out there to do that.
If the motion of the object is rapid, then you have a much bigger problem. One project I did some years back had this problem, and we could not actively track the sudden motion with a microscope. What we did instead was to reduce the microscope magnification, and significantly up the resolution of the high-speed camera (and yes, that was very expensive). At 1500 FPS, we could capture the object as it moved rapidly across the stage, then post-process the resulting frames to center on the object. The obvious limit here is that the object needs to cover a relatively small portion of the overall picture - which limits the magnification you can use. Of course, the offsetting advantage of this method is that you pay more for the camera, but don't have to have a movable stage on the scope.
