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 a complete solution for fast freezing and long-term preservation of blood plasma and other temperature-sensitive biological materials. The plasma freezer maintains a stable storage temperature from -40°C to -86°C using forced-air cooling, dual compressors, an electronic controller, and a high-precision PT1000 sensor. Constructed with a SUS304 stainless steel interior, eco-friendly R290/R170 refrigerants, and a digital temperature display, it delivers dependable storage performance for blood banks, plasma collection centers, hospitals, research laboratories, and GMP-regulated facilities.
The integrated quick-freezing unit rapidly extracts heat from freshly collected plasma before transferring it to the storage chamber, helping preserve coagulation factors and other sensitive biological components. This auxiliary system features a 17 L circulating fluid capacity, operates from -80°C to room temperature, and utilizes a dual-compressor refrigeration system with a key-type microcontroller, PT100 sensor, LCD display, and high-capacity copper tube and aluminum fin heat exchanger for efficient heat transfer. The complete system includes VIP vacuum insulation, multiple safety alarms for temperature, sensor, and door status, corrosion-resistant construction, and energy-efficient operation, providing reliable performance for continuous clinical and laboratory use.
