If classified by major categories, the market share of chromatographic instruments should be the largest. There may be no spectrometer, mass spectrometer or characterization instrument in the laboratory, but chromatographic instruments such as GC, HPLC, CE and TLC can be used.
If we only look at the quantity, maybe 72 1, 722, 75 1 spectrophotometer is the most, because this thing is too cheap, and it is durable and easy to operate in the price range of 500-2000, so it is widely used in colleges, factories, mines and scientific research institutes, but now it has a shrinking trend and is called the classic other one.
If you count some auxiliary instruments, acidity meter and conductivity meter should also be listed. Think about which laboratory dares to say that there is no acidity meter? But because they are auxiliary instruments, we usually don't count them as independent instruments.
The instruments used in chemical experiments are called chemical instruments. Materials can be metered or reacted. Mainly divided into measuring instruments and reaction instruments. These instruments are combined together in a specific way to form a device to achieve the experimental purpose. Commonly used chemical instruments are divided into simple instruments and complex instruments.
