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.

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.
