Multi-compartment burette facilitating titration of multiple reagents based on adjusting assembly

Abstract

The invention discloses a multi-compartment burette facilitating titration of multiple reagents based on an adjusting assembly, and relates to the technical field of titration equipment. The burette comprises a vertical pipe; a first compartment, a second compartment and a third compartment are respectively arranged in the vertical pipe; one circumferential side surface of an arc-shaped vertical rod is fixedly connected with a volume scale line; and the upper surface of a T-shaped sliding block is fixedly connected with an annular inner gear ring. A tooth-shaped structure is fixedly connectedto the circumferential side face, close to the bottom, of the arc-shaped vertical rod. The peripheral side surface of the tooth-shaped structure is meshed with the inner peripheral side surface of theannular inner gear ring; a first titration nozzle, a second titration nozzle and a third titration nozzle are respectively formed in the bottom of the vertical pipe. Through the design of the first compartment, the second compartment, the third compartment, the third annular sliding groove and an inclined rod, various reagents can be filled at the same time, different titration requirements are met, the titration experiment efficiency is greatly improved, experiment failures caused by untimely titration are effectively avoided, and the burette has a supporting function and does not need to use an iron stand.

Description

technical field [0001] The invention belongs to the technical field of titration equipment, and in particular relates to a multi-compartment burette based on an adjustment component to facilitate the titration of various reagents. Background technique [0002] A burette is a volumetric instrument used to accurately dispense an indeterminate amount of liquid. It is made of a slender and uniform glass tube, with a scale on the tube, a pointed mouth at the lower end, and a joint gate in the middle to control the titration speed. When performing a titration experiment, it is necessary to control the amount of titration by controlling the throttle on the burette. [0003] The existing burettes have relatively single functions, and generally can only be filled with one titration reagent. When multiple reagents are used for titration at the same time, the common operation is to constantly replace the burette on the iron stand, which is not only cumbersome to operate, but also grea...

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-compartment burette based on the adjustment assembly to facilitate the titration of various reagents, through the first compartment, the second compartment, the third compartment, the arc vertical rod, the capacity scale line, the ring inner The design of the gear ring, the tooth structure, the third annular chute, the inclined rod, the flushing joint, the diversion hole and the pressurized ball solves the problem that the existing burette has a single function and cannot meet the titration of multiple reagents at the same time, resulting in the titration The efficiency is low, the burette with scale line has high requirements on the production process, and the production cost is high. The general burette is fixed by the iron stand, and the iron stand itself is relatively heavy and not easy to move. Troublesome, relatively high labor intensity, inconvenient flushing inside the burette and low flushing efficiency
