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
, Fort Lauderdale
, Pembroke Park
and Pembroke Pines
. They conduct Fingerprint Analysis

, DNA Analysis
, DNA Testing
and regular health tests as well. Visit their website at www.livescanlabs.com

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.

Why does my mercruiser engine die when put in forward?
Something is too close to the coil wire , CAbles(steering and throttle ) either up front or on the engine do flex when moved.Checkthe movement and operating clearnces at both full and idle positions. All tests can and should be done with engine off, due to Dangerous prop exposure. Good Luck and I would like it if you tell me what you ultimately find. _Ned_

Just aquired an old olympus
Olympus makes good microscopes so you have done well and stereo microscopes are so much nicer to use than singles. As far as cleaning the lenses goes, buy a good quality camera lens blower brush and also a can of compressed air like the ones used for computers. Blow any loose dust hairs etc off with the can of air and then use the brush for anything remaining. If there are fingerprints or grease on the lenses then clean them using camera lens cleaning fluid and lens tissue but make sure all debris and dust are removed first or you may scratch the lenses. In general try not to use anything more than air and a brush unless absolutely necessary. Another option for removing fingerprints etc is to use a "lens pen" with caution. The ones sold for cameras work well but may be too large. They make some smaller ones for cleaning camera sensors and those might work better for the relatively small microscope lenses or just cut the regular lens pen disk to make it smaller. It is just as important to make sure the lens is dust/debris free when using the lens pens.
Low power stereo microscopes often allow you to put on a single magnifier lens in front of the main objectives to increase magnification. Do a bit of searching to find what are options for your model.

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
