Source Plasma Freezing

A Plasma Blast Freezer is a specialized Class II medical device designed for the rapid freezing of fresh frozen plasma (FFP), cryoprecipitate, and source plasma in blood banking and transfusion medicine. Operating at -30°C to -50°C with high-velocity forced-air circulation, these units achieve core temperatures of -30°C in plasma units within 60-90 minutes, preserving labile coagulation factors (Factor V, Factor VIII) and meeting stringent AABB, FDA, CAP, and EU regulatory requirements. Available in benchtop (10-30 unit) and floor (50-200+ unit) configurations with stainless steel construction, programmable microprocessor controls, multi-point temperature monitoring with product simulators, continuous data logging, and multi-level alarm systems. Primary clinical applications include rapid freezing of fresh frozen plasma (within 8-24 hours of collection), cryoprecipitate production, source plasma freezing for fractionation, controlled-rate freezing of blood components, research applications, emergency preparedness, and biobanking preparation. Critical safety requirements include validated freezing cycles, temperature mapping, redundant monitoring, documented freezing curves, and strict adherence to regulatory standards for plasma component quality and patient safety.
