[Science Popularization] Experimental Instruments: A Complete Classification of Laboratory Glass Instruments
Due to the wide variety of glass instruments, a wide range of uses, different shapes, and experimental instruments in different professional fields use some special glass instruments, it is difficult to classify all glass instruments in detail. According to international standards, glass instruments and experimental instruments used in laboratories are generally divided into the following eight categories.

According to international standards, glass instruments and experimental instruments used in laboratories are generally divided into the following eight categories.
(1)Transport and interception devices:Including glass joints, interfaces, valves, plugs, pipes, rods, etc.
(2)Container:Such as plates, bottles, beakers, flasks, tanks, test tubes, etc.
(3)Basic operationexperimental instrumentEquipment:Such as for absorption, drying, distillation, condensation, separation, evaporation, extraction, gas production, chromatography, liquid separation, stirring, crushing, centrifugation, filtration, purification, combustion, combustion analysis of glass instruments and equipment.
(4)measuring experiment instrument:Such as measuring flow, specific gravity, pressure, temperature, surface tension and other measuring instruments., and measuring instruments, dropper, pipette, syringe, etc.
(5)physical measurement experiment instrument:Such as testing color, optical density, electrical parameters, phase change, radioactivity, molecular weight, viscosity, particle size and other glass instruments.
(6)Glass instruments for the determination of chemical elements and compounds:Such as for the determination of arsenic, carbon dioxide, elemental analysis, atomic group analysis, metal elements, arsenic, halogen and moisture instruments.
(7)material experiment instrument:Such as measuring the atmosphere, explosives, gases, metals and minerals, mineral oil, building materials, water quality and other instruments.
(8)Food, Drug and Bioanalytical Instruments:Such as for food analysis, blood analysis, microbial culture, microscope accessories, serum and vaccine tests, urine tests and other analytical instruments.
experimental instrumentMaintenance and maintenanceToImplement“Both maintenance and prevention”The principle of regular maintenance, mandatory, correctly handle the relationship between use, maintenance and repair. Do a good jobexperimental instrument, Cleaning, lubrication, adjustment, tightening and anti-corrosion of scientific and educational instruments, daily maintenance and regular maintenance, and strictly abide by the cycle and inspection and maintenance items specified in the instruction manual.
