Embodiment Construction

[0014] A titration device using a plurality of burettes, which includes a base 1, one end of a main support arm 5 is fixed on the base, the other end of the main support arm 5 is located in the center above the base 1, and the adjustment shaft 4 is fixed on the main support arm 5. A wheel hub 2 is fixed on the bottom end of the shaft 4, and more than one burette clamp 3 is fixed on the side of the wheel hub 2.

[0015] The present invention adopts a plurality of screw holes around the hub 2 to connect and fix a plurality of burette fixtures 3 at the same time, so as to realize simultaneous multi-tube titration and improve efficiency.

[0016] Bolts are welded on the burette fixture 3, and the burette fixture 3 is connected with the screw hole on the side of the hub 2 through the bolts; the angle between the burette fixture 3 and the hub 2 can be adjusted by the bolts.

[0017] The adjusting shaft 4 is fixed on the main support arm 5 through the screw 6; the height adjustment o...

Abstract

The invention discloses a titrating device using multiple burettes. The titrating device comprises a base (1), wherein one end of a main support arm (5) is fixed to the base; the other end of the mainsupport arm (5) is positioned right in the middle of the upper side of the base (1); an adjusting shaft (4) is fixed to the main support arm (5); a wheel hub (2) is fixed to the bottom end of the adjusting shaft (4); and more than one burette clamp (3) is fixed to the side surface of the wheel hub (2). The technical problems that the titrating device in the prior art can only clamp a single burette for titration, time and labor are consumed during measurement of a buffering agent and an indicating agent, manual shaking of a titration container is required for uniformly stirring the reagents in the titration container in the titrating process, and thus the efficiency is low, manpower and material resources are wasted are solved.

Description

technical field [0001] The invention belongs to chemical experiment equipment, in particular to a titration device using a plurality of burettes. Background technique [0002] Chemical titration is a common operation in experiments. The titration device is one of the commonly used devices for chemical titration. At present, most titration devices can only clamp a single tube for titration. It is time-consuming and laborious to measure the buffer and indicator. And the titration process It is necessary to manually shake the titration container to stir the reagents in the titration container evenly; there are problems such as low efficiency and waste of manpower and material resources. Invention content: [0003] The technical problem to be solved by the present invention is to provide a titration device using multiple burettes to solve the problem that the titration device in the prior art can only clamp a single tube for titration, and it takes time and effort to measure t...
