AI Technical Summary
In existing liquid chromatographs, the liquid storage bottle is prone to tipping over due to collisions during the detection process, causing liquid spillage and affecting the stability and safety of the detection.
A liquid storage assembly was designed, comprising a hollow column, a slide bar, a sealing plug, a three-jaw chuck, a clamping seat, and a clamping ring. By adjusting the height of the liquid storage bottle and quick clamping, its stability is ensured, and the stability and ease of operation are improved by supporting blocks, slides, and bidirectional lead screws.
It improves the stability of the storage bottle during the testing process, avoids liquid spillage, enhances the safety and accuracy of the test data, and ensures the convenience of operation and the stability of disinfection.
