Ultra-low temperature freezers −86 °C
Explore Vestfrost, Evermed and Antech ultra-low temperature freezers for laboratories and biobanks: portable units, upright cabinets and chest freezers with capacities from 1 to 838 litres. Choose a freezer operating down to −86°C by usable capacity, sample format, monitoring and installation requirements. The exact temperature range and configuration are listed on each product page.
For biobanks and research laboratories
Freezers in this class are used when a protocol requires ultra-low temperature storage: in biobanks, molecular biology and research laboratories, for DNA/RNA, cell cultures, reagents and other temperature-sensitive samples. The permitted temperature and storage period depend on the material and the method. Equipment should therefore be matched to a documented requirement, not selected only by its lowest temperature.
Portable models can support small sample batches and specialised workflows. Upright cabinets provide organised access for frequently handled inventory, while chest freezers can be practical for archive-style loading.
How to select a −86°C freezer
- Operating range. Compare the target set point and room conditions with the specification of the exact model.
- Capacity. Consider the format of cryoboxes, racks, shelves or inner compartments as well as the litre rating.
- Sample access. Choose a layout that reduces search time and unnecessary door openings.
- Monitoring and alarms. Define temperature logging, local and remote alerts and external monitoring requirements.
- Backup plan. Establish the response to a power failure or planned service before placing critical samples in storage.
- Installation. Check dimensions, doorways, ventilation, floor loading and the electrical supply.
How −60°C storage differs
If the approved method permits an operating range from −40 to −60°C, a dedicated −60°C freezer may be the closer fit. See the −60°C versus −86°C comparison, or return to all medical and laboratory freezers.
Preparing for operation
For accurate selection, provide the target temperature, sample type and quantity, storage format and monitoring specification. Refrigeration equipment qualification can also be planned when required.
What to compare before ordering
| Criterion | What to verify |
|---|---|
| Storage conditions | Material requirements, permitted deviations and measurement conditions |
| Actual load | Usable volume, containers, shelves or baskets and reserve capacity |
| Monitoring | Alarms, logger, data export and independent sensor |
| 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.
