This is something you learn best through hands-on... but here's a couple of sites to help you. For most simple equipment like magnifying glasses or balance scales, use the package insert for details.\n\nhttp://www.ekcsk12.org/science/lelab/microscopeuselab.htm\n\nhttp://www.mdk12.org/instruction/curriculum/science/safety/safety.html

hi,\n\nmatlab sucks for this kind of thing.\n\nyou're better off getting an interface card from national instruments and using labview to do your data acquisition.\n\nhttp://www.ni.com/dataacquisition/

There are sevaral ways of finding microfossils. \n\nIf the sample is a limestone or similar material it can be dropped in acid and left for a few weeks. That will dissolve the limestone and leave the fossils. Then some lab monkey will spend weeks looking at the grit that is left under a dissecting microscope amicroscope with a pair of tweezers. I kid you not. Slowly separating out fossils from garbage.\n\nThe other way to process rock is to slice it cleanly and put the entire spcimen under the micorscope. When a fossil is spotted it can be either maked for later chemical extraction or very gently chipped out.\n\nThe other technique is to collect sediments such as clay or sand and seive them to remove unwanted material. The it's back to the dissection microcope with the tweezers to sort out the rubbish.

Optical Spectrum Analyzer (OSA) is probably what you're looking for...nice for discovering chemical composition of light source and probably a zillion other different things.

I've never used a Roche instrument, however I have used Kodak/Vitros systems. Kodak/Vitros is dry slide technology.\nIt can be a bit expensive however its a reliable instrument. The 950 is a nice machine if you do a lot of lab work and perform a lot of chemistry. The 250/500 models are good for small labs or perhaps doctor's office. I know this much, take the Na+ reagents out of the freezer when you begin to get low ont those slides. That reagent  needs to set out for 2 hrs before loading onto the instrument.\n\nBear in mind, when choosing any instrument for any section of the lab there are certain things to keep in mind: Maintainence schedule, Consumables, Reagent requirements, and of course Technical support and availability of serivce to make service calls.

what kind of lab? physics lab? chem lab? biology lab? ...? be more specific please. \n\nOh Chem lab.  Easy for me. I'm a chemist, ordering stuffs everyday.  Go to http://www.vwr.com\nHere are a few: Volumetric flask, pipette, graduate cylinder, test tubes ... Bunsen burner, FTIR, AA, UV, HPLC, GC ... can't list all here :)

Look for caliper (spelling counts).  Specifically, Vernier Caliper, and micrometer.  \n\nThose are the two major precision measuring tools.  Try the starrett.com web site.  They have a sterling reputation for quality.

For uneven shape , use graduated cylinder.\nFor regular shape, use vernier caliper or micrometer for more accuracy.\n\n(A graduated cylinder (Grad or graduate for short), also referred to as a measuring cylinder, is a type of laboratory glassware comprised of a tall cylinder with a range of calibrated markings that is used for visually measuring the volumes of liquids in a quantitative manner. A graduated cylinder can be made of translucent plastic or borosilicate glass such as Pyrex. Often, the largest graduated cylinders are made of polyethylene or other rigid plastic, making them lighter and less fragile than glass, but more difficult to sterilize.)\nFor more pl. visit:\nhttp://en.wikipedia.org/wiki/Graduated_cylinder
