Anti-sloshing conical flask water bath system

Abstract

Provided is an anti-sloshing conical flask water bath system. The system includes a water bath kettle body, a water bath kettle cover, a fixing block, first magnets and second magnets, wherein a clamping mechanism is installed in the water bath kettle body, each clamping unit includes a spring and a clamping block, one end of each spring is connected with the inner sidewall of the water bath kettle body, and the other end of each spring is connected with one corresponding clamping block; the upper part of the side wall, opposite to one corresponding spring, of each clamping block is arranged as an inclined plane, an arc-shaped groove is formed in the lower part of the side wall, opposite to one corresponding spring, of each clamping block, and a conical through hole is formed in the middleof the fixing block; the first magnets are installed on four sidewalls of the fixing block, and the second magnets are installed on the inner sidewall of the water bath kettle body or the sidewall ofa sieve. According to the anti-sloshing conical flask water bath system, through the arrangement of the clamping mechanism, fixing block, first magnets and second magnets, the three-dimensional movement of a conical flask in the water bath kettle body is limited effectively, and the problem that a failure of an experiment is caused by spilling of reagent liquid in the conical flask due to shakingor falling down, which is caused by the buoyancy and fluctuation of water in the water bath kettle body, of the conical flask during the experiment is solved.

Description

technical field [0001] The invention relates to the technical field of laboratory water bath heating devices, in particular to an anti-shaking conical flask water bath system. Background technique [0002] In the chemical test for the determination of the permanganate index, a 250ml Erlenmeyer flask needs to be heated in a water bath, and the temperature of the water bath is 98°C. Among them, the volume of the sample in the Erlenmeyer flask is 115ml; because the water bath does not consider how to stabilize the instrument in the boiling water bath, it mostly relies on the weight of the instrument itself to maintain a stable state in the boiling water; when placed in the boiling water bath, it is very It is easy to shake and fall, causing the sample to spill out, resulting in the failure of the experiment; in addition, the design of the frosted Erlenmeyer flask only has a stopper. When the water bath is heated, when the temperature reaches above 90°C, bubbling and steaming wi...

Among them, the volume of the sample in the Erlenmeyer flask is 115ml; because the water bath does not consider how to stabilize the instrument in the boiling water bath, it mostly relies on the weight of the instrument itself to maintain a stable state in the boiling water; when placed in the boiling water bath, it is very It is easy to shake and fall, causing the sample to spill out, resulting in the failure of the experiment; in addition, the design of the frosted Erlenmeyer flask only has a stopper. When the water bath is heated, when the temperature reaches above 90°C, bubbling and steaming will occur. Phenomenon, it is also easy to cause the Erlenmeyer flask to be washed down
