AI Technical Summary

Technical Problem

Existing multichannel mixing devices are inefficient and fail to achieve good mixing results when handling complex solvents, making it difficult to meet the automation requirements of the life sciences field.

Method used

A plasmid extraction and mixing device was designed, which uses a steel needle device connected to an extraction pump device. The steel needle is independently inserted into the plasmid reagent, and the extraction pump realizes the suction and discharge action. Combined with the driving device, the mixing is automated. The mixing effect is controlled by adjusting the suction and discharge rate and duration of the steel needle.

Benefits of technology

It achieves automated plasmid mixing, improves mixing effect and efficiency, avoids solvent cross-contamination, and ensures sufficient mixing and thorough cleaning.
