Cell preparation

Choosing the right cryogenic vials

Cryogenic vial selection is a key element in successful cryopreservation and storage of valuable cells and biologicals TruCool® cryogenic vials are made of virgin polypropylene, come sterile packed and have a unique 1D barcode on each vial, which ensures organization and anonymity.

Caps include a thermally-fused elastomer gasket which replaces traditional o-rings and ensures a tight, leak-proof seal with minimized risk of leakage or liquid nitrogen aspiration.  Internal or external threaded screw caps are available for round-bottom or self-standing tubes.

Preparing cold cell suspensions in a biosafety cabinet

CoolBox XT cryogenic vial ice free coolingCryogenic vial preparation is performed under aseptic conditions in a biosafety cabinet. Cell suspensions are typically kept cold (0.5 to 4.0℃) and using ice is problematic for a number of reasons - ice cannot be used in a biosafety cabinet, high sample contamination risk, uneven cooling, disorganization. Cooling inside a hood requires the use of ice an ice-free cooling device. CoolBox™ XT systems offers a variety of ice-free options for keeping cell suspensions uniformly cold and stable inside a sterile hood environment.  Keep up to 48 cryogenic vials or a combination of vials and plates cold (0.5 to 4℃) for up to 16 hours. 

All components of the CoolBox XT system can be sanitized with alcohol and the thermo-conductive CoolRack® cryogenic vial holders and CoolSink® plate holders are autoclavable.  The thermo-conductive properties ensure uniform temperature distribution to all vials and plate wells during handling without the use of ice, batteries or electricity.
