Gradient temperature control pool for biological agent constant-temperature tests

Abstract

The invention relates to a gradient temperature control pool for biological agent constant-temperature tests, and solves the problems that an existing water bath device only has a fixed temperature and cannot meet the requirement of a test with a temperature gradient. The inlet end of a self-flowing groove is higher than the outlet end of the self-flowing groove, a reversely flowing heat exchange return pipe is arranged at the bottom of the self-flowing groove, the inlet end of the self-flowing groove is connected with a hot water tank, the outlet end of the self-flowing groove is connected with a cold water tank, and the cold water tank is connected with a one-inlet two-outlet three-way valve through a return pump; the flow ratio of two outlets of the three-way is adjustable, a first outlet of the three-way valve is connected with the inlet end of the heat exchange return pipe, an outlet of the heat exchange return pipe is connected with a return tank, and a second outlet of the three-way valve is directly connected to the return tank which is connected with a hot water tank through a make-up pump and a heater. After stable operation for a period of time, a relatively stable gradient temperature control interval is formed in the self-flowing groove, and the constant-temperature water bath test requirements of different temperatures are met.

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
