The TSX Series -20 °C freezers offer stable storage without automatic defrost. This prevents unwanted temperature spikes. V-Drive technology ensures reliable performance. Suitable for professional laboratory use.
The Thermo Scientific TSX Series -20 °C laboratory freezers with manual defrost are designed for applications requiring maximum temperature stability. By eliminating automatic defrost cycles, brief temperature rises are avoided. This makes the freezers suitable for enzymes, reagents and other sensitive materials.
These TSX freezers use V-Drive variable compressor technology combined with cold-wall convection cooling. Cooling capacity continuously adapts to the load. As a result, the temperature remains uniform and the cabinet recovers quickly after door opening. The stable operation supports consistent storage conditions at a setpoint of -20 °C.
With a noise level of approximately 52 dB(A), the freezers are suitable for placement directly in the laboratory. The energy-efficient design is ENERGY STAR certified and supports sustainable laboratory setup. Safety features such as alarms, setpoint locking and battery back-up contribute to sample safety.
