The glass is chemically stable, but it is not absolutely unorganized, but the degree of corrosion is in line with the necessary standards. It is a problem that the problem should be paid to the surface of the glass surface adsorption solution due to the corrosive ion into the solution and the surface adsorption solution of the glass surface. Hyfulfffluoric acid is highly corroded with glass, so it cannot be carried out with a glass instrument to perform an experiment containing hydrofluoric acid. The alkali fluid, especially concentrated or hot alkali to clearly corrode glass. Glass instruments for storage bases are also unable to open together if it is a grinding instrument. Therefore, the glass container cannot store the alkali solution for a long time.

General glass instruments, such as beaker, flask, tapered bottle, test tube and tissue, etc., can be brushed from the outer to water from the outer to the outer to water, so that the water soluble substance, partially insoluble material and dust; if there is an organic matter such as oil, It can be washed with depassing powder, soap powder or washes. Wipe with a hair brush with depass or washing agent, then brush clean with tap water, and finally use distilled water or deionized water to wash the inner wall 2 to 3 times. Washing glass instruments should be moist from water and waterless stripes that should be uniform and no water drops. In an organic test, the gear glass instrument is used, and should pay attention to the maintenance of the grinding when scrubbing, and should not use detergent to use the detergent.

For a glass instrument that is not easy to brush or brush with a brush, such as the dripping tube, a capacity bottle, a pipette, etc., which typically pours the washing agent into or in the absorbing container for a period of time, and the scrubbing The agent is poured into the storage bottle, and then brushed with tap water and deionized water.

The sand core glass filter should be cleaned immediately after the use of different precipitates remaining in the filter sand core, and the appropriate washing agent first dissolves the surface precipitated solids, and then repeatedly uses the reduced pressure purifier to repeatedly use the washing All of the residual precipitate is cleaned, and clean it with distilled water, dried at 110 ° C, stored in a dust-proof cabinet.
