A container for storing biological samples

Abstract

The invention provides a container for storing biological samples, which belongs to auxiliary equipment for biological experiments. The technical solution is: a biological sample storage container, including a sealed tank body, the top plate of the tank body is uniformly distributed with several through holes in the circumferential direction, and the through holes are provided with sealing covers that can be opened and closed. On the tank body and above the through hole, a top cover is rotated, and a cylinder corresponding to any of the through holes is opened on the top cover, and the cylinder communicates with the inside of the top cover; The basket for storing samples can pass through the cylinder and the through hole to enter the interior of the tank; it also includes a lifting device capable of lifting the basket from the tank; the bottom of the cylinder is provided with a top cover. The beneficial effects of the present invention are: it can assist in manually taking out the basket placed in the liquid nitrogen tank, and can avoid excessive liquid nitrogen waste and avoid liquid nitrogen causing personal injury.

Description

technical field [0001] The invention relates to auxiliary equipment for biological experiments, in particular to a container for storing biological samples. Background technique [0002] In biological experiments, biological tissues such as blood, stem cells and organs are used. In order to maintain the activity of biological tissues, cryopreservation is required for later removal, thawing and rewarming. [0003] At present, liquid nitrogen tanks are generally used for storage, but in actual use, there are the following problems: the operator needs to open the tank lid when selecting frozen samples, reach out and take out the basket for freezing, and then select the required sample tubes, and then Put the cryopreservation rack back into the tank. First, the temperature of liquid nitrogen is very low, which is easy to cause bodily harm to people; second, in the process of taking out the basket, there will be liquid nitrogen on the basket, causing waste of liquid nitrogen; th...

Problems solved by technology

[0003] At present, liquid nitrogen tanks are generally used for storage, but there are the following problems in actual use: the operator needs to open the tank cover when selecting frozen samples, reach out to take out the basket for freezing storage, and then select the required sample tubes, and then Put the cryo rack back into the tank

First, the temperature of liquid nitrogen is very low, which is easy to cause bodily harm to people; second, during the process of taking out the basket, there will be liquid nitrogen on the basket, resulting in waste of liquid nitrogen; third, when one person operates, Generally, the lid of the tank is not closed until the sample tube is taken out. Due to the large mouth of the tank, liquid nitrogen is easy to volatilize and leak, resulting in waste
