Problems solved by technology

During the titration, the experimenter’s hand is required to squeeze the rubber tube for a long time, which is complicated and difficult to operate. At the same time, in order to ensure the accuracy of the titration, the residual air in the burette needs to be removed before the titration starts. Flexible, air bubble removal operatio

Abstract

The invention discloses a large-capacity alkaline burette, comprising a pipe body with a ruler, a titration head, a glass ball, a flexible rubber tube, a capacity ball, a communication pipe and a regulating valve. The capacity ball is connected to the pipe body through the communication tube, and the regulating valve installed on the connecting pipe. The large-capacity alkaline burette disclosed by the invention has a simple structure, and is convenient to add standard liquid into the burette through the set volume ball, which is convenient to operate, greatly improves the efficiency of the experiment, and reduces the operation difficulty of the alkaline burette.

Description

technical field [0001] The invention relates to a chemical experiment equipment, in particular to a large-capacity alkaline burette. Background technique [0002] Acid-base titration is a commonly used experiment and detection method in the field of basic chemistry. For a long time, the structure and shape of the alkaline burette used in the laboratory has always been a traditional structure, including the tube body and the tube head. The tube head is composed of a rubber tube, a glass ball and Drip-tip composition. The principle of controlling the titration of the standard solution is to squeeze the rubber tube near the glass ball, and a certain cavity is formed between the inner wall of the rubber tube and the glass ball to allow the standard titrant in the burette to pass through. During the titration, the experimenter’s hand is required to squeeze the rubber tube for a long time, which is complicated and difficult to operate. At the same time, in order to ensure the acc...
