A biological specimen bag is a professional device used to preserve and protect biological specimens. Its specifications include the following aspects:

1：Size: The size of the biological specimen bag varies according to actual needs. Common sizes include 20cm x 30cm, 30cm x 40cm, 40cm x 50cm, etc. Depending on the size and number of specimens being preserved, the appropriate size can be selected.

2：Material: Biological specimen bags are usually made of high-strength, corrosion-resistant, non-toxic, and environmentally friendly materials to ensure that the specimens will not be damaged during the preservation process. Common materials include polyester, nylon, polypropylene, etc.

3：Thickness: The thickness of a biological specimen bag is also one of its specifications. Generally speaking, the thicker the specimen bag, the better protection it can provide. Common thickness range is between 0.1mm and 0.3mm.

4：Transparency: Some biological specimen bags have high transparency to facilitate observation and management of specimens. Highly transparent specimen bags are usually made of transparent polyester or nylon materials.

5：Sealing: The sealing of biological specimen bags is also one of its important specifications. Good sealing performance can prevent the entry of air and moisture, thereby effectively protecting specimens from damage such as oxidation and moisture.

6：Durability: The durability of biological specimen bags is also one of the factors that need to be considered when purchasing. Highly durable specimen bags can better protect specimens and extend their service life.

7：Labeling: Biological specimen bags usually have labeling functions to facilitate identification and classification of specimens. Common marking methods include printing, hot stamping, labeling, etc.

To sum up, choosing a suitable biological specimen bag requires consideration of multiple specifications, including size, material, 8：8：thickness, transparency, sealing, durability, and marking functions. Based on actual needs and characteristics of the specimens being preserved, selecting specifications that meet the requirements can better protect and manage biological specimens.
