Our selection of high-performance, low-maintenance chest style Ultra Low Temp Freezers -140 C improve cell viability through stable, long-term preservation and are ideal for critical cryogenic lab storage. Featuring a unique refrigeration system that does not require LN2 as a cooling agent, mechanical cryopreservation keeps the freezer at a uniform temperature and eliminates the dangers of a liquid supply as well as the need for troublesome liquid control. These units are perfect for the long-term storage of biological materials while minimizing operational costs and the level of freezing damage to cells. Designed of the highest quality materials and components, they provide trouble-free service at a lower cost without compromising performance. The chest cabinet is usually constructed of a heavy grade steel with a high impact powder coated exterior finish providing extra durability while a low profile design allows for easier interior access. Superior insulation provides unsurpassed temperature uniformity within the chamber as well as the front to back and top to bottom. These freezers can be configured with alarm systems, audible and visual, that alerts in the event of a power failure or temperature deviation, with a battery backup in case of power outages / interruption, a monitoring system to ensure the freezer is operating properly or in a variety of other configurations depending on your specific freezing needs. Optional inventory racks, fiberboard boxes and dividers are available for easier organization and storage within the freezer. Ultra Low Temp Freezers -140 C provide more storage capacity than a conventionally insulated freezer and are ideally suited for cryogenic storage in laboratories or any other setting which requires the long-term storage of blood and other specimens. They are built by the top brands in the industry providing security and dependability you can count on.
