This section provides an overview for cryopreservation tanks as well as their applications and principles. Also, please take a look at the list of 6 cryopreservation tank manufacturers and their company rankings.
A cryopreservation tank is dedicated containers for long-term storage of biological samples under ultra-low temperature conditions ranging from -76°F to -250°F. Cryopreservation is usually defined as the storage of biological samples in dedicated containers filled with liquid nitrogen (-320°F).
Cryopreservation usually refers to the storage of biological samples in cryopreservation tubes or other containers filled with liquid nitrogen (-320°F). For simplicity, a -76°F freezer may be used.
The term "cryopreservation tank" may refer to the cryopreservation tubes in which the samples are stored or to the container in which the tubes are filled with liquid nitrogen for preservation.
Cryopreservation tanks are widely used in biological and medical research, in the medical field, and in agriculture and animal husbandry.
The purpose of cryopreservation is to preserve cells, tissues, vaccines, etc., safely for a long period while minimizing changes in the characteristics of the samples for use in research and medicine after preservation.
Specific uses of preservation include the preservation of sperm and fertilized eggs, tumor cells and tissues, cultured strain cells, lymphocytes, platelets, bone marrow, and white blood cells, bacteria and viruses, and plant seeds.
They are also used for vaccine preservation, cell banking, storage of artificial insemination samples at livestock farms, and preservation of plant genetic resources, useful strains of crops, and endangered species.
Cryopreservation tubes, called cryotubes or cryovials, are mainly screw-cap type and made of polyolefin resin, a polymer composed of carbon and hydrogen.
In addition, specialized storage containers such as xerotubes and cstraws are used for sperm preservation, and cryotops and cryoloops are used for oocyte and embryo preservation.
Liquid nitrogen cryopreservation tanks are used for long-term cryopreservation of biological specimens by filling them with liquid nitrogen. It has a double-layer structure of an inner chamber suspended from an outer chamber by a neck tube. Temperature stability is maintained by vacuum insulation between the inner and outer tanks and by wrapping them with insulation material.
There are two types of storage vessels: liquid-phase storage vessels in which samples are stored by immersing them in liquid nitrogen filled inside the vessel, and vapor-phase storage vessels in which liquid nitrogen is filled into a tray at the bottom of the vessel and samples are stored above the tray surface.
There are two types of storage containers: one is a type in which a freeze box containing storage tubes is stored in a rack, and the other is a type in which a canister (can) with storage tubes and a chestnut straw attached is stored in a cylindrical canister (can).
