The World?s First Liquid Nitrogen Free Controlled Rate Freezer

Grant Instruments has introduced the world's first liquid nitrogen and refrigerant free 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. 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.
