Problems solved by technology

[0002] The burette is a necessary instrument in chemical analysis and other laboratories. The burettes currently used are divided into two types: acid type and alkali type. Due to the different structures, the two types of burettes cannot be mixed.
If you use an acid burette to hold an alkaline solution, for a long time, it is easy to cause the piston to be connected to the tube body due to corrosion and cannot rotate; Or the glass piston accidentally slipped and broke during the washing process, causing the entire burette to be scrapped, and the traditional acid burette has obvious right-handed operation habits, and the operation is complicated; The latex tube is corroded and must be replaced; while the alkaline burette will cause severe pain to the fingers due to the long-term squeezing of the glass bead during use; corroded or aged
At present, there are also common burettes for acid and alkali, but the structure is complicated, it is not suitable for mass production, the production cost is high, and the packaging and transportation costs are also high; moreover, it is easy to damage

Embodiment 1

[0024] Embodiment 1: as Figure 1-5 As shown, a general-purpose burette is composed of a burette body 1 and a burette 2. The outer wall of the end section 12 of the burette body is made into a plug shape, and the bottom end of the end section 12 of the burette body is closed. , the inner wall of the end section 12 of the burette body inserted into the shape of a plug body is connected with the upper inner wall of the burette to form an integral space, and the side wall of the end section 12 of the burette body is provided with a leaking hole 13 with a diameter of 1.0 mm. The inlet section of the burette head is set as a socket 24 matching the end section of the burette body. The socket 24 of the burette is connected to the end section 12 of the burette body. The burette body 1 and the burette 2 can rotate relatively The connection is not leaking, and the titration head 2 is provided with a drainage groove 22. The drainage groove 22 starts from the socket 24 on the titration he...

Abstract

The invention provides a universal burette, relating to a chemical experiment analytical apparatus and particularly a universal burette for acids and alkalis. The burette is composed of a burette tube body and a titrating head, wherein the bottom end of the tail section of the burette tube body is sealed, and the side wall is provided with a liquid leakage hole; a sheathing port of the titrating head is connected to the tail section of the burette tube body; the titrating head is provided with a diversion ditch; and the diversion ditch extends from the sheathing port of the titrating head to the inner wall of the cavity of the titrating head along the inner wall. The burette product has the advantages of simple structure and high durability, is cheap for mass production and simple to operate, and can not be easily damaged.
