A portable 48-hole cryogenic sample storage box

Abstract

The invention discloses a portable low-temperature sample storage box with holes, which relates to the technical field of detection equipment, and includes a low temperature box and an electrical box. Slide rails, ice crystal storage racks are slidably connected inside the two electric slide rails, and a cold air box is arranged on the inner bottom wall of the low temperature box. The invention is provided with supporting feet, connecting posts and rubber bladders. After the electrical box is separately removed, it is convenient to charge the battery. By setting the electric sliding rail, the ice crystal storage rack and the spring, when a small amount of samples needs to be taken out, it is not necessary to open the box cover. It helps to maintain a low temperature environment. By setting the wind deflector, turntable and wind deflector, the airflow disturbance is larger, making the cold air distribution more uniform, reducing the temperature difference between the upper, lower and inner and outer directions. By setting ice crystal storage racks and ice crystals The box cools the sample for a certain period of time.

Description

technical field [0001] The invention relates to the technical field of detection instruments, in particular to a portable 48-hole low-temperature sample storage box. Background technique [0002] During the detection process, sampling is carried out by using sample bottles, which are generally sampled multiple times to avoid error interference. Therefore, the number of sampling bottles used in each test is large and of different sizes. The sample bottles are usually made of glass material. This makes it difficult to carry the sampling bottle, and it is easy to collide with each other and cause damage. After sampling, the sampling bottle needs to be stored in a low temperature environment. However, most of the existing refrigerators are kept warm by ice cubes and ice packs, and the heat preservation time is not long. , and the effect is not good. Although some low-temperature sample storage boxes are equipped with refrigerators, they need continuous mains supply, otherwise th...
