Labotemp -86°C Ultra Low Freezer ULF-28 is a high-capacity Laboratory Freezer designed for secure long-term sample preservation at ultra-low temperatures from -40°C to -86°C. Engineered for critical applications such as medical freezer storage, vaccine preservation, and DNA preservation, it ensures stable and uniform cooling through a dual refrigeration system. In the event of system failure, the backup cooling system automatically maintains temperatures up to -70°C, safeguarding valuable biological samples, reagents, and research materials.
Built for reliability and efficiency, this advanced ULT Freezer features a microprocessor-controlled system with a 7-inch touch display for precise temperature monitoring (±0.1°C). The robust cabinet with VIP insulation and stainless steel interior enhances thermal stability while reducing energy consumption. Comprehensive safety features including multiple alarms, 72-hour backup battery, door lock, and power failure protection ensure uninterrupted sample preservation. With high storage capacity (588L) and optimized airflow, it delivers consistent performance for demanding laboratory and clinical environments.
