These type of controlled rate freezers are mainly used in the IVF and AI field, they are smaller, one can easily work on a small bench, they are quite and the systems can be quickly set up, and packed away, by the user.
Each CRF consists of a temperature controller, cryochamber, and cryobath. The chamber stands directly in Liquid Nitrogen in the cryobath, and is connected to the controller which regulates the temperature of the specimens.
These controlled rate freezers are ideal for the precision freezing down of vials, straws and blood bags. The temperature range allows flexibility for a wide range of applications and protocols and the -180 ºC end temperature ensures sample integrity when transferring to long term storage.
They can be operated as stand-alone or via a PC (with software)
