AI Technical Summary

Technical Problem

Existing pipettes often have pipette tips that easily detach during use, leading to waste of experimental reagents and system contamination.

Method used

Design a detachable pipette body and pipette tip structure. By setting a groove and sliding hole in the tapered part of the connecting tube, and using the cooperation of the locking tongue and the pressing rod, the pipette tip can be reliably fixed, and the spring action can be combined to ensure a stable connection.

Benefits of technology

This improved the fixation performance of the pipette tip, preventing it from falling off, simplifying the installation and disassembly process, and ensuring the stability and accuracy of the experiment.

Abstract

This utility model discloses a novel pipette, relating to the field of laboratory instruments. The technical solution includes a pipette body and a pipette tip detachably connected to the pipette body. A connecting tube is fixedly installed at the lower end of the pipette body, and the lower end of the connecting tube is tapered. The pipette tip is detachably connected to the tapered portion of the connecting tube. A groove is formed on the tapered portion of the connecting tube, and a locking tongue, shaped like a right-angled trapezoid, is slidably installed within the groove. The smaller bottom surface of the locking tongue faces the lower end of the connecting tube. A sliding hole is formed on the side wall of the connecting tube, with the axis of the sliding hole parallel to the axis of the connecting tube. A pressing rod is slidably installed inside the vertical tube, and the upper end of the pressing rod extends to the outside of the pipette body and is fixed to the release button of the pipette body. The beneficial effect of this utility model is that it makes the connection between the pipette and the pipette tip more stable and tight, thereby improving the fixation performance of the pipette tip and avoiding the problem of easy detachment.
