The Liebherr SFFsg 4001/740 laboratory freezer offers 316 litres of gross capacity with six drawers. It freezes from -9 °C to -30 °C on the natural refrigerant R290. This lets you store larger stocks of sensitive substances in the pharmaceutical industry and the food industry.
SmartFrost limits ice build-up, so you defrost less often. LED ceiling lighting always provides a clear view of the stored substances. Minimum and maximum temperatures remain readable for up to 42 days, also via an app. As a result, you keep the storage conditions clearly in view.
