Constant-temperature sample tank

Abstract

The invention relates to an experiment apparatus accessory and especially relates to a constant-temperature sample tank. The constant-temperature sample tank is characterized in that the constant-temperature sample tank comprises a sample tank main body, the sample tank main body is a tetragonal body of which the center is provided with a square through hole, and two side walls of the sample tank main body are provided with light transmittance holes. A water inlet and a water outlet are arranged below a side wall without a light transmittance hole, and the water inlet and the water outlet are communicated with intersect channels in the sample tank main body. The constant-temperature sample tank realizes accurate temperature control, has a temperature control precision of 0.1 DEG C, realizes fast heating (cooling), and realizes that the time consumed by heating from current temperature to desired temperature is less than 10s. The constant-temperature sample tank guarantees measurement data authenticity and accuracy.

Description

technical field [0001] The invention relates to an accessory of an experimental instrument, in particular to a constant temperature sample pool. Background technique [0002] The constant temperature sample cell is often used in the laboratory, especially in the analysis and research experiments in the fields of biology, chemical industry, and medicine. Conventional constant temperature devices are divided into two types, one is a water bath constant temperature device, which uses water as a heat transfer carrier, and this method is more common; the other is an electronic constant temperature device that uses semiconductor elements as a heat transfer carrier. Thyristors are used for precise temperature control, and the temperature can be controlled to 0.05°C. [0003] It takes a long time for the traditional method to achieve the required constant temperature and accuracy. In addition, due to structural limitations, there will be a temperature difference between the upper a...

Problems solved by technology

[0003] It takes a long time for the traditional method to achieve the required constant temperature and accuracy. In addition, due to structural limitations, there will be a temperature difference between the upper and lower sides of the constant temperature pool, resulting in inaccurate measurement and unable to obtain ideal results.

The electronic constant temperature device is used, although the temperature control is relatively accurate, but its structure is quite complicated, and the technical requirements and costs are relatively high, which is not conducive to popularization and use.
