Description

A portable 48-hole cryogenic sample storage box

technical field

The invention relates to the technical field of detection instruments, in particular to a portable 48-hole low-temperature sample storage box.

Background technique

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 the low-temperature environment cannot be guaranteed. In addition, the existing refrigerators have poor insulation effect, resulting in easy transfer of cold air to the outside. When a single sample needs to be taken out, the usual practice is to open the entire box cover and then take out the target sample. Taking out multiple times will inevitably lead to dissipation of cold air and the ambient temperature of the sample will not meet the standard.
