Dissolution-reaction calorimeter sample cell convenient for discharging

Abstract

The invention relates to a calorimetric device in calorimetry, in particular to a dissolution-reaction calorimeter sample cell convenient to unload, which comprises a glass guide tube, a sample cell bearing unit and a sample cell, the glass guide tube is a fixed part, the sample cell bearing unit comprises a glass rod, a sample cell upper cover and a connecting ring A, the sample pool comprises a support lug, a sample pool main body and a connecting ring B, the glass guide pipe penetrates through the glass rod, the upper end of the glass rod extends out of the glass guide pipe and is in threaded connection with a nut, the lower end of the glass rod is connected with the upper end of the sample pool upper cover, an annular clamping groove is formed in the lower end of the sample pool upper cover, and a notch is formed in the annular clamping groove; a support lug is arranged at the upper end of the sample cell main body, the support lug is inserted into the annular clamping groove through the notch and is supported by the annular clamping groove after the sample cell main body is rotated, a connecting ring A is arranged on the sample cell upper cover, and a connecting ring B connected with the connecting ring A through a rubber rope is arranged on the sample cell main body. The sample pool can fall in by rotating the glass rod, a push rod is not needed, and experimental operation is more convenient.

Description

technical field [0001] The invention relates to a calorimetric device in calorimetry, in particular to a sample cell of a dissolution-reaction calorimeter for easy discharging. Background technique [0002] SRC100 (Constant Environment Precision) Dissolution-Reaction Calorimeter is used to measure the heat released or absorbed during the dissolution process or the reaction process. It provides a constant temperature environment through a high-precision temperature control system, and the electric energy calibrates the generation or absorption of heat, thereby calculating the dissolution rate. heat or heat of reaction. [0003] The traditional SRC100 dissolution-reaction calorimeter uses frosted glass to suspend the sample cell on the receiving unit. If the sample cell is not tightened at the frosted place, the experiment will not start, and the sample has fallen into the Dewar and begins to dissolve or react. Clean the instrument and re-experiment; if the force at the frost...

Problems solved by technology

[0003] The traditional SRC100 dissolution-reaction calorimeter uses frosted glass to hang the sample cell on the receiving unit. If the sample cell is not tightened at the frosted part, the experiment will not start, and the sample has fallen into the Dewar and starts to dissolve or react. Clean the instrument and re-test; if the sample cell is tightened too hard at the frosted part, when the baseline is stable and the sample is dropped, use the push rod to push the sample cell to drop the sample, which may not make the sample cell drop in time, and repeat the operation of pushing the sample cell It will make the baseline fluctuate greatly and affect the experimental results
