Temperature balance sample storage tank for biological experiment

Abstract

The invention discloses a temperature balance sample storage tank for biological experiments, and belongs to the field of experimental equipment. The temperature balance sample storage tank for the biological experiments comprises a base, a heat preservation cylinder is rotationally connected to the base, a stepping motor is connected between the bottom end of the heat preservation cylinder and the base, a plurality of evenly-distributed inserting grooves are formed in the heat preservation cylinder, a sample storage pipe is inserted into the slot, a temperature regulation and control frame matching with the heat preservation cylinder is fixedly connected to the base, a flow guide pipe matching with a movable insertion pipe is installed on the heat preservation cylinder, and a heat insulation observation plate matching with the heat preservation cylinder is connected to the temperature regulation and control frame in a clamped mode. The solution of the temperature balance sample storage tank can achieve that when biological samples are stored and cultured, the various different samples can perform real-time temperature detection, and can perform cooling treatment on a single sample storage tube in time when the sample storage temperature change exceeds a set range, so that the safety of long-distance transportation of biological samples is ensured.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to a temperature-balanced sample storage tank for biological experiments. Background technique [0002] Many biological samples are very sensitive to temperature, and the storage temperature will directly affect the quality of biological samples, so biological samples need to be stored and transported with special means and devices. For example, the standard storage temperature for platelet samples and apheresis leukocyte suspension samples is usually 10-25°C, and the standard storage temperature for whole blood and erythrocyte blood (excluding frozen red blood cells) samples is usually 2-8°C to minimize cell While speeding up the metabolism, it does not negatively affect the nutrients and enzymes that maintain cell activity. [0003] At present, biological samples are mainly stored and transported in refrigerators, and the containers or sample bags containing biological sampl...

AI Technical Summary

Problems solved by technology

[0004] The above conventional method of storing and transporting biological samples has disadvantages: 1. It is impossible to guarantee that the temperature in the refrigerator during storage and transport is within the storage temperature range of biological samples, especially for biological samples whose storage standard temperature is 10-25°C. When the ambient temperature is not higher than 10°C, the temperature in the refrigerator will be lower than 10°C, thereby affecting the quality of the biological sample; 2. The position of the container or sample bag containing the biological sample is not fixed in the refrigerator, Easy to slide during transportation, even if the container or sample bag containing biological samples is protected, there is a risk of breaking due to collision
