Drying of laboratory glassware

[Abstract]:

In chemical experiments, it is often necessary to use a dry instrument, so after the instrument is washed, it should be dried. Dry the instrument beforehand to avoid drying when it is used.

Drying In chemical experiments, the drying method should be used to dry the instrument before the experiment. After washing the instrument, try to drain the water and then dry it. For example, the beaker can be placed in the cabinet; the distillation flask, the conical flask, and the measuring cylinder can be inverted on the small wooden stake of the test tube rack; the condensation tube can be clamped and placed vertically in the cabinet. After standing for a day or two, the instrument is allowed to dry. You should plan to use the sporadic time in the experiment to wash and dry the instrument needed for the next experiment, so you can save a lot of time when you do the next experiment.

Drying with a gas dryer After the instrument is washed, the residual moisture in the instrument is exhausted, and then the instrument is placed on the porous metal tube of the airflow dryer. Pay attention to adjusting the temperature of the hot air. The airflow dryer should not be used continuously for a long time, otherwise the motor and the heating wire are easily burned out.
