The CB Series from Russells Technical Products

Russells CB series cryogenic freezers are capable of achieving temperatures of -300º F to +500º F. To be able to withstand this extreme temperature difference, Russells has incorporated special construction techniques in addition to welded structural steel framing and heavy duty welded stainless steel liners. As with all Russells cryogenic freezers, we are continuously striving to provide you, our customers, with the best ultra cold freezers available. Since 1972, our freezers been used in liquid nitrogen cryogenic freezing applications around the globe, adding continually to a cryogenic knowledge base that is second to none.

We offer a complete range of cryogenic freezers found in the table below to reliably preserve your samples. A Russells application engineer can assist you in selecting the freezer configuration and size that's best for you or we can custom design any standard freezer configurations.
