Laboratory Freezers
Natural or forced air circulation
Laboratory freezers can freeze and store frozen samples.
Taking care of the quality of our products, in our offer you will not find a two-function device called “laboratory fridge-freezer”. Our refrigerators do not have an integrated freezer inside like home appliances. Our fridge-freezers are two-chamber devices – one chamber is a refrigerator, the other is a freezer. Bearing in mind the concern for device parameters and their functionality, we have created few product categories: laboratory refrigerators, laboratory freezers and ultra-low freezers. Laboratory refrigerators are equipped with a cooling system – they keep the temperature lower than the ambient temperature, however their temperature range doesn’t reach negative values. Usually it is 0-10 or 0-15°C. In the case of our laboratory freezers, the temperature inside the chamber may reach -25/-40°C. The temperature goes even lower in ultra-low freezers – up to even -86°C.
WITH NATURAL AIR CONVECTION
The ZLN 85 freezer and the three ZLN-T freezer models with available capacities 130, 210 i 310 litres are natural-air appliances. The freezers are available with Smart and Smart PRO controllers, and their compartments can be made in C (comfort), CS (comfort/S), P (premium) and PS (transform/S) versions.
WITH FORCED AIR CONVECTION
The ZLW-T freezers are devices with forced air circulation. Models are available with capacities of 210 and 310 litres. By using a fan, the stability and uniformity of the temperature in the chamber is greatly improved, and the cartridge is cooled faster. The effect of faster cooling of the load is particularly beneficial in situations where the chamber must be opened frequently.
