The utility model content

The utility model is at the deficiencies in the prior art, a kind of thermostat of reagent container is provided, its temperature-detecting device by in accepting body, being provided with, it is the feedback of temperature sensor information and control device start-up temperature regulation device is heated or refrigeration automatically to accepting body, thereby realize accepting constant temperature in the body, guarantee that promptly placing this to accept the intrinsic container that is loaded with chemical reagent can be in a specific range of temperatures all the time, thereby overcome the generation that causes the chemical reagent denaturalization phenomenon in the prior art because of externally temperature influence, guaranteed the biological sample dehydration dramatically, film-making, staining reaction is being carried out smoothly, has improved the biological sample film-making effectively, dyeing quality.

For realizing above technique effect, the utility model will be taked following technical scheme:

A kind of thermostat of reagent container, comprise the body of accepting that is used to accept the container that is loaded with chemical reaction reagent, the described body of accepting comprises at the bottom of wall and the device, described accepting is provided with temperature sensor in the body, described accepting is provided with the temperature control device that possesses heating and refrigerating function on the body, this thermostat comprises that also receiving temperature sensor detects the control device of information with heating of start-up temperature regulation device or refrigeration in addition.

Described temperature control device is arranged to be accepted at the bottom of the body device, and described temperature sensor is arranged on the wall of accepting body.

Described temperature control device is arranged at the outer surface of accepting at the bottom of the body device, and the described body of accepting is to be made by the solid conductive heat material at the bottom of the device at least.

Described temperature control device comprises heater and chiller, and described heater is arranged at the outside, and chiller press be located at heater and accept at the bottom of the body device between.

Described heater is an electric boiling plate, and chiller then forms for the refrigeration semiconductor fabrication.

Describedly accept the body wall outside and the temperature control device arranged outside has heat-insulation layer.

Described temperature sensor is arranged on the wall of accepting body.

According to above technical scheme, can realize following beneficial effect:

1. the utility model provides a kind of thermostat of reagent container, it is by being provided with temperature sensor being used to accept the accepting of container that is loaded with reagent in the body, and accept at this temperature control device is set on the body, this thermostat comprises that also receiving temperature sensor detects the control device of information with heating of start-up temperature regulation device or refrigeration simultaneously, thereby realizing accepting is in specific range of temperatures all the time in the body, guarantee that promptly the temperature environment in the thermostat is most appropriate to preserve reagent all the time, prevent that reagent from going bad because of the variation of ambient temperature, thereby have influence on the biological sample dehydration, film-making, carrying out smoothly of staining reaction;

2. described temperature control device comprises heater and chiller, described heater is an electric boiling plate, and chiller forms for the refrigeration semiconductor fabrication, and described heater is arranged at accepts outer surface at the bottom of the body device, chiller is pressed and to be located at the bottom of heater and the device between the outer surface, simultaneously describedly make by Heat Conduction Material at the bottom of accepting the body device, therefore, the utility model can guarantee that the information that heating-up temperature rises or the refrigeration temperature descends in time is delivered in the thermostat, further guarantees the temperature adjusting ability of thermostat;
