They can provide important data and information for many fields such as clinical medicine, food safety and environmental monitoring.

[0003] Among them, some microbial samples need to be pre-processed before some microbial experiments. For example, the microbial culture vessels are spray-coded by a microbial sample pre-processing system, and then the corresponding experimental sample liquid and culture matrix are added to the culture vessels step by step based on the spray-coded information, and finally shaken.
