Overview

The Fisherbrand Isotemp GTFBG72RPGA is designed to provide centralized refrigerated storage for laboratories with high sample volumes. Three independently opening glass doors improve organization while reducing cold air loss by allowing users to access only the section of the cabinet they need. The large interior accommodates substantial inventories of laboratory materials while maintaining excellent airflow throughout the cabinet.

Positive forced-air circulation distributes conditioned air evenly across all storage shelves, helping maintain temperature uniformity during continuous operation. Adaptive defrost technology minimizes frost accumulation while reducing unnecessary temperature fluctuations, and the digital microprocessor controller continuously monitors cabinet performance to protect valuable research materials. Whisper-quiet operation makes the refrigerator well suited for laboratory environments where noise reduction is important.
