A multi-compartment burette for convenient titration of multiple reagents based on an adjustment component

Abstract

The invention discloses a multi-compartment burette which is convenient for titration of various reagents based on an adjustment component, and relates to the technical field of titration equipment. The invention comprises a standpipe; the inside of the standpipe is respectively provided with a first compartment, a second compartment and a third compartment; the side of the arc-shaped vertical rod is fixedly connected with a capacity scale line; the upper surface of the T-shaped slider is fixedly connected with a ring Inner gear ring; the side of the arc-shaped vertical rod is fixedly connected with a toothed structure near the bottom; the side of the toothed structure meshes with the inner side of the annular inner gear ring; the bottom of the standpipe is provided with a first titration nozzle and a second titration nozzle. mouth and third titration nozzle. Through the design of the first compartment, the second compartment, the third compartment, the third annular chute and the inclined bar, the present invention can fill multiple reagents at the same time and realize different titration requirements, greatly improving the efficiency of titration experiments , effectively avoiding the failure of the experiment caused by untimely titration, the invention has its own support function, and does not need the use of 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
