CT-4T.6C Plasma Thawer for Manufacturing Cryoprecipitated AHF

CT-4T.6C Plasma Thawer Defroster
  • Thaws 12 plasma bags (450 ml) of Fresh Frozen Plasma (FFP) in 6.0°C water in about an hour
  • The only countertop plasma thawer designed for manufacturing Cryoprecipitated AHF
  • Rapid thawing does not allow Factor VIII to dissolve into solution before centrifuging; leads to a significant increase in yield
  • Enables labs to manage their work flow much more efficiently because of the predictable and rapid thaw time (as compared to thawing overnight in a refrigerator at 6.0°C)
  • Plasma bag ports kept out of water; hands remain dry during loading and unloading
  • Bright white, corrosion-resistant, sanitary PVC construction is easy to clean & maintain
  • Temperature setting preset to 6.0°C (adjustable from 5.0°C to 20.0°C) accurate to ±0.1°C
  • WxDxH: 91cm x 66cm x 46cm (36in x 26in x 18in)

The CytoTherm CT-4T.6C Plasma Thawer is a laboratory instrument designed specifically for the manufacture of Cryoprecipitated AHF.  It consists of a recirculating water temperature bath with a patented rocking action (US Pat No. 6,007,773) and an external chiller to maintain the necessary 6.0°C water temperature in a room temperature environment.  Lab work flow can be managed more efficiently because of the predictable and rapid thaw time (as compared to thawing overnight in a refrigerator at 6.0°C).  By the time that the plasma is centrifuged and the Cryoprecipitate is separated, the next batch is thawed and ready to be centrifuged.

The CT-4T.6C comes with a rack that will thaw up to 12 plasma bags (450 ml) at a time. The operator never comes in contact with the water in the bath when handling the plasma bags. The rack keeps the entry ports of flat-frozen plasma bags out of the water so an overwrap bag is not necessary.
