AI Technical Summary
The existing pipette tip test box is inconvenient to open due to its tight seal, which affects testing efficiency and ease of operation.
A pipette tip test box comprising a cover and a base was designed. It adopts a limiting plate, a lever, and a balancing vent structure, combined with a wedge block and a locking block to achieve a semi-sealed design, simplifying the opening and closing process. It can also be directly connected to the testing device via the lever, simplifying the testing process.
It enables convenient opening and closing of the pipette tip test box, reduces the vacuum adsorption effect, improves testing efficiency and ease of operation, and simplifies the batch testing process.
