AI Technical Summary
Existing laminar flow hoods are not convenient for cleaning callus tissue in multiple sterile culture dishes at the same time. Manual operation makes it difficult to ensure uniformity, resulting in inconsistent cleaning effects and long cleaning time.
An ultra-clean workbench was designed, comprising an oscillation assembly, a placement rack, a cover plate, and a locking assembly. The placement rack is driven by a servo motor to oscillate back and forth, enabling simultaneous cleaning of multiple culture dishes. The locking assembly prevents solution from splashing out. After cleaning, the culture dishes are removed simultaneously using a pick-and-place assembly.
This method enables simultaneous cleaning of multiple culture dishes, ensuring the uniformity of callus tissue and cleaning efficiency, reducing the operation time of laboratory personnel, and improving work efficiency.
