How to choose the right configuration

select the usable volume and holding time for the expected LN₂ consumption;
match the neck diameter to filling, sample access and evaporation requirements;
confirm whether canisters, racks, roller bases, pumps or monitoring are required.

For biological sample storage, the internal organisation system and sample format should be checked separately from the vessel volume.

Questions before selection and procurement

Can compatibility be determined from dimensions alone?

Dimensions are only part of the check. Provide the vessel, rack or holder reference, container format and manufacturer-confirmed compatibility list.

Why can nominal and working capacity differ?

Sample count depends on containers, internal accessories and the loading arrangement. Compare quotations using the same loading format.

Which documents should be requested before ordering?

The exact model manual, configuration list and performance figures with test conditions. Agree preparation, monitoring and maintenance separately.

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.
