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.

Seems like solvent A and B are confused
By convention solvent A is the aqueous solvent and solvent B is the organic one, so the designation seems to be right. The baseline does not always raise with the increasing amount of solvent B, it depends how steep is the gradient.

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

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

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.
