Container for biological material aqueous solution

Abstract

A container for an aqueous solution of biological material is disclosed. The container comprises a shell, an inlet and outlet is formed in the top of the shell, a cover is installed on the inlet and outlet, and a plurality of silicone tubes communicated with the interior of the shell are installed on the cover; wherein a heat preservation layer is fixedly arranged on the outer portion of the upper end of the shell and the periphery of the outer portion of the inlet and outlet. The container for the biological material aqueous solution adopts the stainless steel shell, and the liquid level area in the upper part of the shell is smaller than the liquid level area in the lower part of the shell, so that low-temperature concentration and damage and breakage of the container can be prevented, heat transfer caused by heat dissipation can be reduced, and the service life of the container is prolonged. A conical ice layer is prevented from being formed on the contact surface of the biological aqueous solution at the top of the container and air, and the safety and stability of the container are improved.

Description

technical field [0001] The invention relates to the field of biochemical experiment equipment, in particular to a container for biological material aqueous solution. Background technique [0002] Biological materials generally include proteins, DNA, RNA, biological products, blood samples, cell suspensions, tissue suspensions, etc., and in order to make biological materials have a long shelf life and facilitate transportation, cryogenic storage is usually required. The way of cryopreservation is usually: placing the container containing the biological material in a freezer, so that the biological material is frozen. [0003] Among them, most of the containers are plastic bottles or bags and glass containers. At present, there are many biological containers made of PC material on the market, such as: Nalgene's PC freezer bottle and Cyduo's freeze-thaw bag. The disadvantages of containers made of these materials are: 1. Under low temperature conditions, the plastic material o...

AI Technical Summary

Problems solved by technology

The disadvantages of containers made of these materials are: 1. Under low temperature conditions, the plastic material of the container will cause changes in physical properties, resulting in its fragility; 2. At the contact surface between the biological aqueous solution and the air in the container, due to convection and heat The heat transfer of radiation will cause the biological aqueous solution on the contact surface with the air to freeze into an ice state first, and then form a cone-shaped ice layer. internal pressure, causing significant mechanical stress and even destroying the container

However, it has the following disadvantages: 1. It needs to be set according to the volume of the container itself, if the size is not suitable, it will not be able to achieve good thermal contact, so that the heat insulation effect is greatly reduced; 2. Hot parts are not conducive to transportation; 3. There are inner walls of heat insulating parts and outer walls of the container between the disguised material and the biological material in the container, resulting in reduced heat insulation effect
