The Grant Asymptote EF600 is the world’s first nitrogen and cryogen free controlled rate freezer. It has been specifically designed for use in human and animal IVF applications for the cryopreservation of embryos, stem cells and spermatozoa but can also be used for a wide range of freezing applications.

Unlike conventional controlled rate cooling equipment, the EF600 poses no contamination risk and can be used in cleanrooms. The EF600 fits neatly on a bench-top and its performance in terms of samples frozen and successfully recovered is proven to be directly comparable with that of a standard liquid nitrogen freezer.

Main applications: The EF600 is a versatile piece of equipment which can be used for the cryopreservation of a wide range of samples, including:

• Human and veterinary IVF
• Stem cells
• Clinical and research samples, e.g. lymphocytes and tissue culture cells in conventional cryovials
• Cord blood in flexible bags
• Matrix type tubes – containing cell suspensions
• The EF600 may also be integrated into robotic systems, including biorepositories and biobanks
• The freezer may also be operated as a portable device: ideal for many veterinary and conservation applications
