How to clean the laboratory glassware? What are the cleaning methods for laboratory glassware?

In the laboratory, there is a relatively special class of apparatus, said special because they are made of glass, such as our familiar beakers, test tubes, etc., in addition to many other kinds. For these supplies, how do we clean it?

Cleaning laboratory glassware generally has three common cleaning methods.

Manual manual cleaning of laboratory glassware.

Advantages: better adaptability, the ability to choose according to different types of dirt and the degree of contamination.

Disadvantages: cleaning quality in general, it is difficult to achieve a balanced and stable, bad record, traceability, and poor testability

Bottle washing machine cleaning laboratory glassware.

Ultrasonic cleaning laboratory glassware.

Advantages: especially suitable for glassware cleaning with complex surfaces and fine lumen.

Disadvantages: ultrasonic cleaning and then water for cleaning and drying

In addition, ultrasonic cleaning machine in the laboratory industry is mainly used to clean beakers, test tube wall dirt, and is used to mix, extraction, emulsification and other auxiliary role. Because the ultrasonic energy can penetrate the inner wall of the glassware and fine crevices, small holes, dead ends, so it can be applied to any glassware, test tubes, beakers, parts or assemblies cleaning. When the cleaned parts for precision glassware, parts or accessories, ultrasonic cleaning often become to meet its special technical requirements of the cleaning method.
