The TSX Series enzyme freezers offer stable -20 °C storage for sensitive enzymes. Manual defrost prevents temperature spikes. V-Drive technology ensures reliable performance. Suitable for professional laboratory use.
The Thermo Scientific TSX Series -20 °C enzyme freezers are developed for stable storage of enzymes and other temperature-sensitive reagents. These models combine manual defrost with a cold-wall cooling system. This effectively prevents temperature fluctuations that can occur with automatic defrost cycles.
The freezers use V-Drive variable compressor technology that continuously adapts to the load. Combined with cold-wall convection cooling, this results in a uniform temperature distribution and fast recovery after door opening. This supports consistent storage conditions at a setpoint of -20 °C.
Both models are supplied as standard with enzyme baskets for organised storage. The lockable door, visual and acoustic alarms and battery back-up enhance sample safety. Thanks to the low noise level, the freezers are suitable for placement directly in the laboratory.
