BRIGHT CLINI-RF Rapid Freezer
Ideal for Snap Freezing (aka Blast Freezing)
The Scilogex Clini-RF Rapid Freezer is a small, free standing, top opening, ultra low temperature freezer. Its function is to rapidly freeze (snap freeze) tissue specimens ready for cryotomy or for storage (eliminating the usage of liquid nitrogen, LN2). Inside the Clini-RF are two cylindrical chambers, the upper chamber is held at -40°C and the lower at -80°C.
The lower chamber can be filled with a liquid medium such as 3M™ Novec™ Engineered Fluid HFE-7100 (excellent environmental, health and safety profile), into which specimens can be immersed. Alternatively, an aluminum block can be incorporated into which a specimen holder or chuck can be fitted. The upper chamber is used as a short term storage area for specimens after they have been initially frozen in the lower chamber.
A seven day timer can be fitted to the Clini-RF and is available as an accessory. This means that during the hours when the Clini-RF is not being used it can be run in a ‘standby’ mode with both the upper and lower chambers running at -40°C, thus saving power. At the start of the working day it can be switched to its normal operating mode and the lower chamber can be brought down to -80°C. An alternative configuration is available where a fixed block is incorporated in the lower chamber and the rapid freezer evaporator coil is taken into the block to give an even faster rate of cooling. Please note that liquid coolant cannot be used with this option.
