Laboratory refrigerator Polaris series

dilution

Traditional cryogenic storage involves immersion in liquid nitrogen, while vapour storage houses samples on a shelf above a liquid reservoir. Polaris is different. By housing liquid nitrogen in a jacket around the Polaris chamber, we have created a truly dry system. Key Features - Liquid nitrogen stored in a thermal jacket that surrounds the storage chamber; reducing cross contamination risks, minimalizing hazards related to liquid nitrogen and achieving a temperature of -190°C with no restrictions to chamber access. - Wide opening for easy sample access – samples are easy to locate and retrieve, vapour cloud clears within a short moment (ideal for frequent access) - Temperature probe is placed at top of the chamber, thermally insulated from the chamber wall – ensures uniform temperature throughout the chamber to ensure all samples are safe. Accurate storage temperature performance to ensure sample viability. - Fully automated or manual liquid nitrogen filling – the samples are kept stable and maintained in specified conditions, without interference from liquid nitrogen top-up. - Liquid nitrogen can be supplied from smaller cryogenic vessels or large scale bulk containers – can act as a standalone system or as a new addition to an existing cryopreservation facility. - State-of-the-art monitoring and control capability - simple and safe to operate, designed with outstanding stability.
