Overview
Labotemp Plasma Blast Freezer ULF-31 combines a 425 L ultra-low temperature plasma freezer with a dedicated 17 L rapid blast freezing unit, providing an integrated solution for fast freezing and long-term preservation of blood plasma and other temperature-sensitive biological materials. The plasma freezer maintains stable storage temperatures from -40°C to -86°C using forced-air cooling, dual compressors, an electronic controller and a high-precision PT1000 sensor. Constructed with SUS304 stainless steel interior, VIP vacuum insulation and eco-friendly refrigerants (R290/R170), it delivers dependable storage performance for blood banks, plasma collection centers, hospitals, research laboratories and GMP-regulated facilities.

Quick-Freezing Unit Summary
The integrated quick-freezing unit rapidly extracts heat from freshly collected plasma before transfer to the storage chamber to help preserve coagulation factors and other sensitive biological components. The auxiliary quick-freezing system features a 17 L circulating fluid capacity and operates from -80°C to room temperature. It uses a dual-compressor refrigeration system, key-type microcontroller, PT100 sensor, LCD display and a high-capacity copper tube + aluminum fin heat exchanger for efficient heat transfer. The overall system includes multiple safety alarms, corrosion-resistant construction and energy-efficient operation for continuous clinical and laboratory use.
