Q:How to choose and use the cryo tubes ?
A:The strain cryovials tube is mainly composed of three parts: preservation solution, cryovials tube and small ceramic beads. It is a container for the preservation of strains in the laboratory, which is used for the preservation or transfer of strains. Porcelain beads are used for the adsorption and preservation of bacteria.
During use, the bacteria are inoculated in a preservation tube and placed in a -20°C or -80°C environment for long-term storage. (-20ºC can be stored for one year, -80ºC can be stored for two years).
The preservation of bacterial strains is always an essential task in the laboratory. For a long time, a variety of methods such as plate passaging, slant passaging, and freeze-drying have been formed.
Storage method: As the storage time increases from short to long, the complexity of storage and the requirements for corresponding equipment are also gradually increasing. How to obtain the best relationship between the preservation time and the complexity of preservation is the key to the preservation method of strains.
Steps:
1. Directly scrape the fresh culture grown on the plate and place it into a cryovials tube
2. Generally, one plate of pure culture can save two cryovials
3. When using, use an inoculation needle to take out a small ceramic bead from the cryovials tube and directly streak the plate or place it in the corresponding enrichment solution
Product principle
1. The material of the cryovials tube is polypropylene, which can withstand the low temperature of -197ºC.
2. There are about 25 porous small ceramic beads in the cryovials tube. The surface of the small ceramic beads is porous, and bacteria can be easily adsorbed on it.
3. The cryovials tube is filled with a bacterial cryovials protection solution to protect the strain from the temperature change of the preservation solution and the influence of ice crystals. achieve long-term storage.
Sterilization and preservation:
The entire cryovial is sterilized by Ethylene oxide and can be stored at room temperature before use.
Store for 1 year before use.
application
cryovials tubes can store general bacteria, harsh bacteria, molds, yeasts and other fungi can also be stored in cryovials tubes under low temperature conditions, so cryovials tubes are widely used in clinical fields (preservation of clinical drug susceptibility test strains), disease Control areas (monitoring the preservation of isolated strains), strain preservation centers (daily use and preservation of strains), and pharmaceutical companies (preservation and use of positive control strains), etc.
Note: In principle, all strains can be preserved in porcelain bead cryovials. The principle of strain preservation is that spontaneous mutation during DNA replication leads to strain degradation. Therefore, it is necessary to create a metabolically inactive state, a dry, low temperature, anoxic, and nutrient-poor environment. The closer the created environment is to this state, the better the preserved strains. the longer the time.
However, it should be noted that due to harsh bacteria (such as Haemophilus influenzae, Naisseria meningitidis) and other special bacteria, they need to be stored at -80°C or lower to achieve longer-term storage.
Q:What machines you have in your factory?
A:Ethylene oxide automatic sterilization equipment,Automatic film sealing machine,full automatic injection molding machine,Automatic plastic tube extruder,Automatic packing machine, automatic filter element assembly machine, automatic blow molding machine, automatic vacuum forming machine,Automatic extruding&blow molding machine,Laser cutting machine, high precision cutting machine, robot hand,CNC machining center, Automatic lathes, automatic grinding machines, automatic milling machines, and etc..
