Gradient temperature control cell for constant temperature test of biological agents

Abstract

The invention relates to a gradient temperature control pool for constant temperature test of biological preparations, which solves the problem that the existing water bath device can only have a fixed temperature and cannot meet the requirements of a temperature gradient test. The inlet end of the self-flow tank of the device is higher than the outlet end, the bottom of the self-flow tank is provided with a reverse-flow heat exchange return pipe, the inlet end of the self-flow tank is connected with a hot water tank, and the outlet end of the self-flow tank is connected with a cold water tank and a cold water tank. The tank is connected to a three-way valve with one inlet and two outlets through a return pump. The flow ratio of the two outlets of the three-way valve is adjustable. The first outlet of the three-way valve is connected to the inlet end of the heat exchange return pipe, and the outlet of the heat exchange return pipe is connected to the return flow. The second outlet of the three-way valve is directly connected to the return tank, and the return tank is connected to the hot water tank through the make-up pump and the heater. After a period of stable operation, the invention forms a relatively stable gradient temperature control interval in the self-flow tank to meet the requirements of constant temperature water bath tests at different temperatures.

Description

technical field [0001] The invention belongs to the technical fields of biology, medicine and gene, and relates to a biological preparation testing device, in particular to a gradient temperature control pool for constant temperature testing of biological preparations. Background technique [0002] In recent years, my country's economy and technology have developed rapidly, and great progress has been made in the field of life sciences. Related companies in my country have invested a lot of resources in research and development in related fields such as biology, medicine, and genetic engineering. The development of related fields such as biology, medicine, and genetic engineering is inseparable from a large number of experimental studies, and the test of biological preparations generally has a relatively constant requirement for the test temperature. The constant temperature test is generally realized by means of a water bath. In a conventional constant temperature test, eac...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing water bath device can only have a fixed temperature and cannot meet the requirements of the temperature gradient test, and provides a gradient temperature control pool for the constant temperature test of biological preparations, which can pass through the artesian tank and reflux The reverse flow heat exchange of the heat exchange tube forms a gradient temperature control pool whose temperature gradually decreases from one end to the other end, which is convenient for multiple constant temperature tests with different temperature requirements to be carried out at the same time
