The laboratory freezer ET 04 for ultra low temperatures (-50 °C to -85 °C) offers excellent performance and is suitable for cooling the liquid for Gehman and TR testers, and other low temperature tests, as well as a wide range of other applications.

This is a highly cost-effective series of laboratory freezers that offers excellent performance, stable cooling, and good operational economy, suitable for a wide range of applications.

The ET 04 freezers can maintain stable temperatures as low as -85 °C – a requirement for the long-term storage of sensitive biological samples, research materials, and vaccines

The freezers offer exceptional operational reliability, thanks to a simple, robust design with few moving parts in the dependable compressor system – ensuring a long service life and minimal maintenance requirements.

The design is highly durable, featuring hard-wearing materials, sturdy handles, heavy-duty hinges, and built-in locks to prevent unauthorized access. A digital controller that features an acoustic temperature alarm is also included as standard equipment.

These laboratory freezers are equipped with exceptionally thick insulation, ensuring that the temperature rises very slowly in the event of a power failure. The ET 04 series for ultra-low temperatures is also equipped with additional inner lids; these keep the freezing-cold air at the bottom of the unit even when the main outer lid is opened, thereby minimizing temperature fluctuations.

Environmentally friendly and energy-efficient refrigerants based on hydrocarbon gases significantly reduce energy consumption and environmental impact.
