Kryo 750-30 Features & Technical Specifications

The Kryo 750-30 is a flexible cryogenic system designed for
freezing of Bone Marrow, Stem Cells, Pharmaceutical Cell Lines, Skin, Cord Blood and other critical samples in high volumes. It is
designed for freezing of samples in bags, ampoules and straws.
It's 2 button operation is unique and it's standard PC software enables password protected multiple protocols. The Protocol stage “trigger on sample”, chamber temperature, or time. The unique forced laminar flow cooling system ensures most efficient, even cooling. The Top, or Front opening provides for easy loading, and the heated door seal prevents freezing shut at cryogenic temperatures. The Inner chamber removable for sterilization
Standard operating features include:
  Start above ambient
  Controlled heating
  Comms port for PC connection
  Fast cooling rates
