Ultra-low temperature storage freezer | RoSS.ULTF

Typically, ultra-cold temperature freezers can achieve temperatures as low as -80 °C, which sets them apart from mini fridges, upright freezers /deep freezers that are used for food storage like ice cream in households or ice makers for a large family. While interior light via LED light, door alarm, the size of the single storage baskets, free delivery and warranty may be the decisive factors when buying a household device, ultra-cold storage freezers need to provide not only extremely low temperatures, but also the highest accuracy and cost-effectiveness. Storage density (how many cu ft / cubic feet of cold storage) is also a key factor in the considerations on which ultra-cold storage freezer to choose.

In contrast to the usual household chest freezers or upright freezers with wire baskets that can be found at various retailers including Amazon next to whirlpools and other rather ordinary household products, ultra-cold temperature freezers are highly specialized devices far more powerful than fridge-freezers or the extra-freezer on casters. They can reach temperatures that household devices – even the bestselling, best chest freezers – cannot achieve with cold air from an ordinary compressor.

Although ULT freezers might share some typical functions with small chest freezers (like a power-on indicator light that helps to become aware of power outage), ultra low temperature freezers need not only to provide lower, but also more stable temperatures than a compact chest freezer, since it contains far more delicate substances.

The ultra-cold freezer RoSS.ULTF is used all along the biopharma industry, from laboratories to transport experts and in biopharma companies. Since it offers high storage density and is easily stackable, it is extremely flexible in use and can be integrated in processes from lab to bulk scale.

There is a wide range of products that can be stored and shipped in single-use bags within a laboratory fridge or freezer. The RoSS.ULTF is compatible with RoSS Shells, made to protect these very bags and to facilitate a seamless transition between the freezing/thawing and storage processes. Products stored and shipped this way include drug substances, monoclonal antibodies, mRNA and gene therapies, temperatures as low as -80°C.

However, there are certain products that need to be stored at even lower temperatures, such as cell therapies or gene-modified cell therapies: This is where cryogenic freezers come into place, with the RoSS.LN2F able to reach temperatures down to -180°C.

Ultra-low temperature freezers are designed to achieve extremely low temperatures, required for example for a safe storage of many biologics. Frequently used insingle use technologies.
