Biochemical reaction cabinet

Abstract

The invention relates to a biochemical reaction cabinet. The biochemical reaction cabinet comprises a box body equipped with a box door, and a lightning component arranged in the box body and used for providing light. The biochemical reaction cabinet also comprises temperature control members, a control member and a temperature sensor. The temperature control members comprise a heating device and a refrigeration device. The arranged temperature sensor can obtain the temperature in the box body in real time, then the temperature value is sent to the control member, the control member carries out comparison with a temperature set value, if the practical temperature is higher than the set value, the refrigeration device is controlled to run, when the practical temperature is lower than the set value, the heating device is controlled to run, and thus the temperature is kept constant. The heating device and the refrigeration device are arranged to control the temperature of the box body accurately, the temperature in the box body is controlled in a large scope, after the box door is closed, the interior of the box body is sealed, no air circulation is generated inside and outside the box body, no material exchange is carried out, temperature control precision is achieved, and thus the temperature in the box body can be kept constant.

Description

technical field [0001] The invention relates to a biochemical reaction cabinet, which belongs to the field of biochemical reaction equipment. Background technique [0002] In the laboratory, in order to precisely control the biochemical reaction, it is usually necessary to place the biochemical reactant into a constant temperature and constant pressure reaction box. For example, Chinese patent document CN104338501A discloses a light-adjustable photochemical reaction box, including: box body, sample holder and a control system, the box body includes a bottom plate, a cover plate, a left side plate, a right side plate, a front side plate and a rear side plate; the inner surfaces of the left side plate and the right side plate are provided with a light source; the front side The plate and the rear side plate are provided with fans; the sample rack is fixed on the bottom plate and is parallel to the left side plate; the sample rack is provided with a temperature sensor; the cont...
