Titration device with accurate zero adjustment

Abstract

The invention provides a titration device with accurate zero adjustment, which comprises a liquid storage bottle, a connecting pipe, control valves, a titration pipe and a titration pipe rack. Because the two control valves are both arranged at the lower end, the operations of liquid replenishment, zero adjustment and titration can be finished by a sitting operator. The titration device with the accurate zero adjustment has the advantages that the accurate zero adjustment can be realized, the liquid level is also kept at the same zero position accurately, the metering is accurate, the cost is saved, the disassembly and the assembly are convenient and quick, and the like. The titration device with the accurate zero adjustment is simple to operate, is convenient and quick and is easy to master; the vision errors are greatly reduced; and hundreds of samples can be titrated by the full liquid storage bottle without replenishing, so that the working efficiency can be enhanced by more than 60 percent, and the labor strength is reduced by more than 80 percent.

Description

technical field [0001] The invention relates to a titration device for accurate zero adjustment. Background technique [0002] The acid-base titration device is a common experimental instrument in various chemical, chemical, pharmaceutical, biological, physiological, biochemical and other laboratories and laboratories, and is widely used in various experiments and assays. At present, the general-purpose acid-base acid-base burette has the following disadvantages. First, the acid-base burette must be manually zeroed by the operator when it is used. The zeroing often needs to be repeated many times to complete. The test needs to be repeated several times to confirm the results. This just causes the waste of manpower, material resources and time. When the acid-base burette is installed on the workbench, the liquid level is relatively high. When zeroing, the operator must keep his sight line level with the liquid level. The operator needs to stand up from his seat when repleni...

Problems solved by technology

At present, the general-purpose acid-base acid-base burettes have the following disadvantages. First, the acid-base burettes must be manually zeroed by the operator when they are in use. The zeroing often needs to be repeated many times to complete. The test needs to be repeated several times to confirm the results

This results in a waste of manpower, material resources and time

When the acid-base burette is installed on the workbench, the liquid level is relatively high, and the operator must keep his line of sight at the same level as the liquid level during zero adjustment. Increase the labor intensity of the operator, and the shorter ones are more strenuous
