Medical and laboratory freezers
Select medical and laboratory freezers by the documented storage conditions, sample count and working routine. The catalogue includes several temperature classes, upright cabinets and chest freezers. A lower minimum temperature alone does not make an instrument better suited to your task.
Comparing temperature classes
Choose the relevant section below and compare the exact model operating range with the protocol. Permitted conditions and storage duration are defined separately for reagents, medicines and biological materials. An equipment temperature class does not establish a universal sample shelf life.
Organising storage
Match usable volume to the actual container count. Racks, cryoboxes, shelves, baskets and inner doors affect loading and access. For frequent retrieval, consider labelling, opening time and the model’s documented temperature recovery performance.
Monitoring and installation readiness
Agree alarms, data recording, an external sensor and a power-failure response plan before ordering. Check dimensions, the delivery route, ventilation clearances and electrical requirements. Compare energy consumption under equivalent measurement conditions.
Choose the appropriate section
| Equipment | Selection focus |
|---|---|
| −20…−35 °C | Medical and laboratory freezers | Medical and laboratory freezers by Vestfrost, Snaige and Evermed, with model-specific limits of −20, −22, −25, −30 or −35 °C. Select by operating range and intended use. |
| −40 °C | Laboratory and plasma freezers | Evermed PDF, Antech MDF-40U and Vestfrost VT −40 °C freezers. Select by net volume, controls, monitoring and documentation requirements. |
| −60 °C | Low-temperature freezers | Vestfrost VT and Evermed LCSDF low-temperature freezers for laboratory and industrial applications. Compare each model’s operating range, net capacity and equipment. |
| −86 °C | Ultra-low temperature freezers | −86°C ultra-low temperature freezers for laboratories, biobanks and long-term biological sample storage. Vestfrost, Evermed and Antech models. |
| −150 °C | Cryogenic freezers | Antech cryogenic equipment: mechanical MDF −150 °C storage freezers and LN₂-powered CryoVita controlled-rate freezers for sample preparation. |
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.
