Description

Technical Field

[0001] This utility model relates to a titration station, specifically a titration station for high-reliability organic synthesis chemistry experiments. Background Technology

[0002] In organic synthesis experiments, a titration stand (also known as a burette stand or burette stand) is a support device used to fix and stabilize burettes, funnels, or other experimental instruments. Its core function is to provide a stable operating platform for experiments requiring precise control of liquid addition or continuous reagent addition. However, existing titration stands are not very stable when fixing and stabilizing burettes, which may cause the burettes to slip or tip over. For example, Chinese utility model patent application number CN202420910053.6 discloses a chemical analysis titration rack and titration stage device, including a titration stage housing and a door disposed at the opening end of the titration stage housing. A stepped hole is formed in the middle of the top surface of the titration stage housing, and a titration table is disposed within the cavity of the stepped hole. A hollow tube is disposed at the center of the top surface of the titration table, and a burette is disposed on one side of the hollow tube. The burette is connected to the hollow tube via a stabilizing component, and an LED light strip is disposed within the cavity of the hollow tube. A supplementary lighting component is disposed within the cavity of the titration stage housing, and a voltage adjustment knob is disposed on one side of the door surface. In this patent, the burette is only fixed by a single stabilizing frame. In certain situations, if the stabilizing frame becomes loose or flipped, the burette may slip or tip over.
