BIOFREEZER SYSTEM OPTIONS

Cryochamber Options

Biogenics FREEZE CONTROL biofreezer systems consist of a temperature controller, cryochamber, and cryobath. A range of FREEZE CONTROL cryochambers is available to accommodate different specimen containers (e.g., straws and/or cryovials, security straws, etc.), with cooling rates appropriate for virtually any protocol. There are two cryobath sizes available, interchangeable according to customer preference.

FREEZE CONTROL cryochambers are unique. Their patented design ensures symmetrical heat transfer from all specimens to liquid nitrogen. The highly conductive material used for the chamber ensures a very high degree of temperature uniformity of each specimen whether Liquid Nitrogen levels are high or low. Specimen temperature is monitored continuously and is measured by a precision platinum temperature sensor permanently mounted in the core. Specimens can be safely accessed for manual seeding, without exposing them to temperature fluctuations. The conductive core of the chamber, and the tight thermal coupling between specimens and core, ensure that latent heat is efficiently removed during the nucleation process.

All cryochambers are available in two styles: STANDARD or FAST, designated by product code suffixes "S" or "F", respectively. The STANDARD design is suitable for most applications, whereas the FAST models are appropriate for applications where a higher- speed cooling rate is desired. We are pleased to guide you in the selection of cryochambers to match your requirements.

The Standard CC23S Straw Cryochamber is included with all biofreezer systems unless the customer order states otherwise.
