I know nothing about the device, but it reads like you forced the door into a wedged position and it's stuck there. I would gently pry at it to get it past the "wedge", then study the mechanism to see whether the actual latch is broken, or just out of position.

The Intel QX3 is not compatible with 64 bit operating systems. It will not work. Sorry.

You can either reinstall Windows 7 as a 32-bit version or purchase a QX5 model which is compatible with Windows 7 64-bit.

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 www.livescanlabs.com.

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.

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_

One has to have a compatible operating system with the correct driver, Your computer operating system must be set for reading the USB port as a video device, f you are able to read any data from the scope you should also check firmware version against the manufacturer's latest revision. Also suggest you download the operator's manual from the manufacturer's site.

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.

Have you seen this video with advice?

Another tip is to cool the rotor down (either by getting the refrigeration to kick in if it is a refrigerated centrifuge) or perhaps by filling the the rotor with tubes full of ice-water (or something colder...). Everything will shrink slightly, which means the rotor will become a slightly looser fit on the shaft.

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.

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.
