Reagent storage and refrigeration box capable of cooling

Abstract

The invention discloses a reagent storage and refrigeration box capable of cooling. The reagent storage and refrigeration box capable of cooling comprises a box body, wherein a box cover is arranged on the box body, a reagent seat is arranged inside the box body, a liquid nitrogen tank is arranged in the middle of the reagent seat, and an air outlet surface valve, a linear telescopic motor, a reflecting plate and a nozzle tube arranged on the air outlet surface valve are arranged on the liquid nitrogen tank. According to the reagent storage box, when a temperature sensor detects that the temperature is increased, a controller starts the linear telescopic motor, the linear telescopic motor drives the nozzle tube on the air outlet valve to be started, liquid nitrogen is sprayed out to realize automatic control of the temperature inside the box body, the function of the reflecting plate is to reflect the sprayed liquid nitrogen to the reagent seat, a reagent tube on the reagent seat is cooled by using the atomized liquid nitrogen, and the refrigeration of a reagent is realized.

Description

technical field [0001] The invention relates to the technical field of preservation of biological reagents, in particular to a reagent preservation box capable of cooling down. Background technique [0002] With the development of various detection technologies, the types of detection reagents are becoming more and more abundant. At the same time, the requirements for the external environment including production, storage, transportation, and use are getting higher and higher, especially the technical indicators of storage temperature are becoming more and more accurate. [0003] The current kits, especially the detection kits, generally only have the function of outer packaging, and still need to use other equipment to complete low-temperature storage in the cold chain transportation link, thus greatly increasing the transportation cost and the uncertainty in the reagent transportation process. And some new kits with low-temperature storage function also use the insulation ...

Problems solved by technology

[0003] The current kits, especially the detection kits, generally only have the function of outer packaging, and still need to use other equipment to complete low-temperature storage in the cold chain transportation link, thus greatly increasing the transportation cost and the uncertainty in the reagent transportation process

And some new reagent kits with low-temperature storage function also use the insulation shell and cold storage agent to cooperate with each other to achieve passive cooling. Such products obviously cannot independently control the temperature change in the box to adapt to different storage temperature requirements.
