Thermo Scientific UGL3020A Upright Laboratory Freezer -20°C, 29.2 cu ft, Manual Defrost

The Thermo Scientific UGL3020A is a high-performance upright laboratory freezer designed to provide stable and efficient storage for critical biological and chemical samples. It features a 29.2 cubic foot interior capacity ideal for bioprocessing and molecular diagnostics workflows requiring reliable low-temperature sample preservation down to -20°C.

Key technical attributes include a manual defrost cycle that minimizes temperature fluctuation during defrosting, ensuring consistent sample integrity. The freezer uses a cold wall convection cooling system, eliminating blowers or fans and reducing energy consumption, which enhances operational efficiency in biotechnology and clinical diagnostic environments. Its industrial-grade, hermetically sealed compressor lowers noise emission, supporting noise-sensitive research facilities.

Thermo Scientific incorporated CFC-free urethane foam insulation for optimal thermal stability against ambient temperature changes, crucial for long-term sample storage in synthetic biology and biomanufacturing labs. Security and safety are enhanced through a key-operated triple-position master switch controlling power supply, alongside audible and visual alarms for overtemperature, undertemperature, and power failure—critical features for monitoring sensitive biological samples.

Physical specifications include dimensions of 38in L x 34in W x 79in H, and a weight of 445 lbs (actual). It is widely adopted in biomedical engineering and live-cell imaging laboratories where reliable low-temperature storage solutions are essential. The UGL3020A's robust design and advanced features make it suitable for diverse research domains requiring stable and secure sample preservation under precise controlled conditions.
