The Alkali Scientific CryoFreeze™ 12 Place Cell Freezing Container is optimized for controlled rate freezing of samples stored in 5 mL cryogenic vials. When placed in a –80 °C freezer, the system provides an alcohol free cooling rate of approximately –1 °C per minute, supporting reliable cryopreservation of a wide range of cell types and cell lines. Constructed with high density polyethylene foam and an alloy based thermal core, the container promotes uniform heat transfer for consistent and reproducible freezing performance. Its non absorbent foam design helps maintain freezer integrity without introducing liquids that could affect surrounding samples. The low thermal mass allows the container to return quickly to room temperature after removal, improving workflow efficiency between runs. Designed for 12 standard 5 mL cryogenic vials, the uniform radial layout promotes consistent freezing rates across all vial positions, while numbered vial locations simplify
