We all talk about the instruments, supplies and reagents commonly used in the laboratory, which

To say that the instrument, the middle school stage, mainly is some alcohol lamp, funnel, beaker, reagent bottle, dispensing funnel, long neck funnel, burette, measuring cylinder and so on the cheaper, usually a few tens of dollars it. Reagents are the same as those in junior high school. High school is an analytical experiment, what acid-base burette, volumetric flasks, vacuum pumps, electronic balance, condenser tubes, pipettes, conical flasks, Brinell's funnel, a few hundred dollars. Then the university stage with more, organic experiments with electronic stirrers, crucibles, thermostatic bath, flasks, three flasks, thermometers. Then there are electronic devices, such as infrared, ultraviolet, liquid chromatography, gas chromatography, mass spectrometer, hydrogen flame ionization detector, are hundreds of thousands of millions of dollars, very expensive. Anyway, there are so many instruments that it would be impossible to name them all.
