There are 4 ways to clean the sampler vials wall by autosampler vials: the autosampler vials is mainly made of glass raw materials, and it is rarely plastic raw material. The one-time use of the injection vials is costly, wasteful, and has serious environmental pollution. Most laboratories are The injection vials is cleaned and reused. At present, the most common method for cleaning the sample vials in the laboratory is to add washing powder, scrubbing agent, organic solvent and acid and alkali lotion, and then rinse with a custom small test tube. There are many defects in the washing method. The washing agent and water are used in a large amount, the washing time is long, and the dead corner is simple. If it is a plastic injection vials, it is easy to leave a brush mark on the inner vials wall, which takes up a lot of human resources. About lipids and Protein residue is a serious glassware. When analyzing samples, it is very important to clean the sample vials.
According to the degree of pollution, the cleaning method is selected according to the degree of pollution. There is no fixed form.
Summary of 4 methods and methods for automatic injection vials cleaning vials wall:
