Description

Plate-type cold storage container capable of reducing condensation and temperature control

The present invention relates to a plate-type cold storage container capable of reducing the occurrence of condensation and controlling the temperature. In particular, the low temperature of the refrigerant from the refrigerant storage box is conducted to the sample tube mounting plate, thereby preventing the denaturation of samples or reagents used in a laboratory or laboratory. It relates to a plate-type cold storage container capable of reducing the occurrence of condensation and controlling the temperature so that the middle work can be stably performed.

In general, in a laboratory or laboratory, it is often necessary to perform work in a low-temperature environment as a measure to prevent denaturation of samples or reagents contained in a certain tube.

In order to maintain a low temperature environment, a method of inserting a tube containing a sample or reagent into ice made with an ice maker, or a method of freezing an aluminum sample tube plate or a sample tube plate filled with refrigerant in a freezer is used. .

The method for maintaining a low-temperature environment is a commonly used method when using ice, but the ice contained in a styrofoam container melts over a certain period of time to generate water. There is a disadvantage that the ice needs to be replaced frequently as it is not fixed and can be submerged in water or melted water can get into the tube and cause contamination.

To compensate for these shortcomings, various types of plates that are frozen and used are sometimes used.If an aluminum sample tube plate is used, condensation occurs on the plate surface due to the difference between the plate temperature and the room temperature when used after freezing cold in the freezer. The surroundings were contaminated by moisture due to the water, and the plate temperature rose quickly and the cold air retention time was shortened (10 minutes or less based on 10℃), making it difficult to work at low temperatures for a long time.

In the case of the refrigerant filling plate for the sample tube device, which is another type of plate, it is made to maintain a low temperature for a long time because the refrigerant is filled inside, but like the aluminum sample tube plate, water is not dried due to condensation due to temperature difference. Of course, there is a problem in that the tube is not well inserted or the entire plate is bent due to deformation of the shape due to the expansion pressure generated when the refrigerant is frozen.

On the other hand, a cold storage container equipped with a low-temperature storage function of Registration Utility Model Publication No. 20-235997 (2001.6.15) was proposed, and the proposed cold storage container forms a dry ice filling space on the cover of the cold storage container, thereby flowing downward. The inside of the cold storage container can be kept at a low temperature by the cold air of dry ice, so that the storage material can be refrigerated or frozen to keep it fresh, but there was a difficulty in applying it to insert a tube containing a sample or reagent in a laboratory or in a laboratory.

In addition, a cold storage container of Registration Patent Publication No. 10-1981688 (2019.5.17) was proposed, and the proposed cooling container increases the storage space by making the thickness of the insulation material inserted into the outer case thin, and stacks a plurality of cold storage containers. As a result, the convenience of storage and transportation is improved, and there is a problem in that it is difficult to apply a tube containing a sample or reagent in a laboratory or laboratory, and temperature control is difficult.
