- The Grant Asymptote EF600 is a liquid nitrogen and refrigerant free controlled rate freezer ideal for use in cleanroom environments

CAMBRIDGE, England, May 16, 2007 – Grant Instruments, (www.grant.co.uk), a world renowned manufacturer and supplier of custom and own-brand scientific, life sciences and data acquisition products, has introduced the Grant Asymptote EF600 controlled rate freezer designed specifically for use in human and animal In vitro fertilisation (IVF) applications for the cryopreservation of embryos, oocytes, stem cells and spermatozoa.

The Grant Asymptote EF600 uses an electronically powered Stirling Cycle Cryocooler as its cooling source and is the world’s first liquid nitrogen and refrigerant free controlled rate freezer. This removes the risk of samples being contaminated during freezing and means that unlike conventional refrigerant based cooling equipment used in IVF laboratories this product can be used where a high level of air quality is required.

Simple to operate and very quiet, the Grant Asymptote EF600 is extremely cost effective compared to liquid nitrogen systems. Its small footprint means that it can easily be used on the laboratory bench top as a stand alone freezer or linked to a control PC to provide data logging and programming flexibility. The freezer may also be operated as a portable device making it ideal for many veterinary and conservation applications.

The Grant Asymptote EF600 enables the cooling rate to be precisely controlled allowing for good sample recovery upon thawing, directly comparable with that of a standard liquid nitrogen system. In addition, the temperature remains below minus 100ºC at the end of the cycle until the freezer is turned off. An uninterruptible power supply (UPS) ensures complete sample security in the event of power failure.

A variety of sample holders as well as application specific preset linear and non-linear cooling programs are available. For other laboratory freezing applications, sample holders can be modified and cooling programs can be optimised for any particular cell type.
