Problems solved by technology

The high school chemical experiment instrument, the traditional burette, needs to be read with the naked eye. When titrating, it is necessary to pay attention to the titrated capacity at all times to prevent excessive titration, which will lead to the failure of the experiment. In this way, there is a large error in the artificial reading. When titrating, it is necessary to pay attention to the titration process at all times, and it takes a lot of money. energy in this step, resulting in a decrease in overall experimental efficiency

Abstract

The invention discloses a high-precision automatic titration device. A high-precision automatic titration device, including a power device (10), the power device (10) includes a housing (101), and the bottom of the housing (101) is provided with a transmission rod buckle (109) for connecting the transmission rod (9), The transmission rod buckle (109) and the transmission rod (9) are detachable; the bottom of the shell (101) is detachably connected with the first positioning guide rod (8) and the second positioning guide rod (11), and the shell (101) The top is provided with a control panel (105). By setting the anti-off device, a transmission rod can be combined with multi-section threads, the length of the transmission rod is reduced, the transmission distance is increased, the compactness of the equipment structure is improved, and it is convenient for transportation and storage. By setting the automatic control system, the function and ease of use of the equipment can be improved, the efficiency of the experiment can be improved, and the operation steps during the experiment can be reduced.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to a high-precision automatic titration device. Background technique [0002] Burettes are divided into alkaline burettes and acid burettes. The former is used to measure liquid reagents that corrode glass tubes; the latter is used to measure liquids that corrode rubber. The capacity of the burette is generally 50mL, and each large division of the scale is 1mL, and each large division is divided into 10 small divisions, so each small division is 0.1mL. The accuracy is one percent. It can be accurate to 0.01ml. A burette is an elongated tubular container with a stopcock at one end and a scale indicating the measurement. Generally, the reading on the upper scale is smaller, and the reading on the bottom is larger. The high school chemical experiment instrument, the traditional burette, needs to be read with the naked eye. When titrating, it is necessary to pay attention to t...
