Ultra Low Temperature (ULT) freezers

Utilising an innovative heat exchange system that runs on liquid nitrogen, the Variō Series Freezer is able to maintain a user-defined temperature (+/- 5°C) anywhere between -20°C and -150°C. This environmentally-friendly freezer can accommodate up to 94,500 2.0 ml vials.

The Variō Series offers many distinct advantages over traditional ultra-low mechanical freezers and a significant operating cost saving. It operates on just 1% of the electricity of a mechanical freezer and can result in an overall decrease in operating costs by up to 70%.

There are significant sample security and stability advantages with the Variō freezers. With traditional -80°C mechanical freezers internal temperature will increase so drastically if the door is open for just 3 minutes that sample temperature can increase by as much as 10°C. In comparison the Variō series offers consistent internal temperatures even when the lid is open. It also offers much longer hold times than traditional ultra-low mechanical freezers. For instance, if the liquid nitrogen supply is removed or interrupted it will take 4 days for the internal temperature to rise from -80°C to -60°C. In contrast if the power supply is removed from a mechanical freezer it will warm up by the same amount in just 6 hours.

CryoEase® Microbulk Solutions

CryoEase® microbulk technology is a modern concept where your gas is supplied by filling on-site vs. the traditional method for smaller volume usage, where gas is supplied by swapping full for empty cylinders and dewars. CryoEase® microbulk supply features specially designed trucks with integrated controls and flexible storage tank options. End usage can be provided as pure gases, cryogenic liquids or gaseous mixtures via a blender installed at your site.
