Medical and laboratory freezers −20…−35 °C

This category includes medical and laboratory freezers with model-specific lower temperature limits of −20, −22, −25, −30 or −35 °C. The −20…−35 °C label describes the group of models, not a shared operating range for every unit. Evermed LFG models reach −20 °C, selected LF models reach −22 °C, other LF/BLCF models reach −25 °C, and LDF models reach −30 °C. Check the actual operating range and intended use in each product specification before selecting a model.

Installation	Dimensions, ventilation clearances, room temperature and power

Questions before selection and procurement

Is the temperature in the category name enough for selection?

No. Compare the specific model range with the documented storage requirements of each material. Storage duration is defined by the material documentation, not by the refrigerator or freezer name.

How should required capacity be assessed?

Count the actual containers and reserve stock, then check shelf or basket arrangements. Total volume, usable volume and package capacity are different measures.

What should be agreed for temperature monitoring?

Alarm functions, independent measurement, record format and the deviation response procedure. Include temperature mapping and qualification separately where required.

What is needed to compare quotations?

A technical specification and an equivalent equipment list for each option. Specify quantity, installation or use location, compatible accessories and documentation requirements. This supports comparison of the complete cost of the required solution.

Configuration and documentation

Record the exact model, version, standard equipment and optional items in the quotation. Request the manual and specification with the conditions under which performance figures are determined. Agree procurement documentation, availability, delivery, warranty and service work for the specific supply.
