Isothermal LN2 Freezers from Panasonic

Isothermal LN2 Dry Storage Freezers eliminate the common problems faced when using traditional liquid nitrogen storage systems. Manufactured by Custom BioGenic Systems (CBS) and sold by Panasonic Biomedical, the freezers are ideal for laboratories seeking reliable long-term storage of biological samples at ultra-low temperatures.

CBS Isothermal LN2 Freezers feature a patented liquid nitrogen jacket surrounding a stainless steel interior for exceptionally controlled, uniform storage temperatures in the -190˚C range. This is achieved without any contact between samples and liquid nitrogen, which is completely excluded from the internal chamber. Risks of cross contamination are therefore eliminated, and all available storage space in the chamber is left for samples. The design also improves user safety, removing the risk of splashing or contact with harmful liquid nitrogen.

Uniform temperature gradients are ensured across the vessel, along with a unique vapour circulation system for reduced cold air loss and improved visibility during openings. Full-width lids can thus be used for quick, unrestricted access to sample racks. The Series 2301 Auto-fill and Monitor System controls the automatic filling of the liquid nitrogen jacket and provides the user with an easy to read overview of the freezer temperature and status.

The main benefits of Isothermal Freezers include:

• No liquid nitrogen in the storage area
• Outstanding temperature uniformity in the -190˚C range
• Series 2301 Auto-fill and Monitor System
• Comprehensive alarm system with remote alarm contact
• A wide selection of inventory systems for vials and bags
