Cryogenic Freezer

Listing ID #4668882

CRYOGENIC FREEZER with temperature range -140oC to -155oC offer mechanical cryopreservation for long-term biological storage. Cryopreservation is the process where cells or whole tissues are preserved by cooling to sub-zero temperatures. The freezer also known as Cryogenic Storage Freezer. At low temperatures, any enzymatic or chemical activity which might cause damage to the material is effectively stopped. Liquefied gases, such as liquid nitrogen and liquid helium, are used in many cryogenic applications. Liquid nitrogen is most commonly used. Cryogenics is used in applications such as cord blood preservation and livestock breeding for the following materials:

• Examples include:

• semen cryopreservation

• Blood

• Stem cells. It is optimal in high concentration of synthetic serum, stepwise equilibration and slow cooling.

• Umbilical cord blood

• Tissue samples like tumors and histological cross sections

• Eggs (oocytes) in oocyte cryopreservation

• Embryos at cleavage stage (that are 2, 4 or 8 cells) or at blastocyst stage, in embryo cryopreservation

• Ovarian tissue in ovarian tissue cryopreservation

• Plant seeds or shoots may be cryopreserved for conservation purposes. Etc.

• Microprocessor based controls(HMI+PLC optional)
• USB ports for PC connectivity.
• RS 232/485 connectivity
• Real time data acquisition system.
• Application Specific Ultra Low Temperature Compressor
• Reduces Cell Cross Contamination
• Increased Cell Viability - Long Term Preservation.
• The high capacity liquid nitrogen cylinder offers a large cooling reservoir with the reassurance of an extended hold time at the protocol end temperature.
• safety features to help protect against power failure and PC failure when running with software
• Incident monitor provides visual and audible warnings of system abnormalities for increased sample protection.
• CFC/HCFC-free refrigerants maximize cooling and minimize environmental impact
• chart recorder for better temperature monitoring (optional)
