Cell Freezing Container for Controlled-Rate Cryopreservation
Description
Cell freezing containers are laboratory devices designed to achieve controlled-rate cooling (approximately -1°C/min), ensuring high cell viability during cryopreservation and long-term storage.
Why Controlled-Rate Freezing Matters
| Factor | Impact on Cell Viability |
| Cooling rate | Prevents intracellular ice formation |
| Temperature uniformity | Ensures consistent freezing across samples |
| Reproducibility | Standardized freezing conditions for experiments |
| Cell recovery | Higher post-thaw survival rate |
Cells should be cooled gradually (~1°C per minute) to avoid damage from ice crystals and osmotic stress during freezing.
What Is a Cell Freezing Container?
A cell freezing container is an insulated device used to hold cryogenic vials and control the cooling rate when placed in a -80°C freezer. It enables gradual temperature reduction before transferring samples to liquid nitrogen storage.
- Designed for 1 mL and 2 mL cryovials
- Ensures uniform cooling across all samples
- Used as an alternative to programmable freezers
After controlled freezing, samples are typically transferred to -80 degrees Celsius (-112 degrees Fahrenheit) for long-term preservation.
