The comprehensive modular concept allows selection of the optimal freezer box combinations for individual storage demands. The outer footprint dimensions (133mm) of these freezer boxes are compatible with common freezer rack systems and the different inner grid variants provide for an optimal fit to all typical tube formats: cryogenic tubes, microcentrifuge tubes, 15, 25 and 50mL conical tubes and other laboratory vessels. This space-saving approach together with the application benefits resulting from the listed product features help to optimise your long-term storage and archiving of samples.

• Take full advantage of freezer space thanks to the flexible and optimised combination options for the different box formats.
• Whether freezing to -86°C for sample storage or autoclaving for 20 minutes at 121°C for sterilisation, Eppendorf storage boxes retain their shape
• Eppendorf 15 and 50mL conical tube boxes are equipped with ventilation slots for an evenly distributed freezing process, this prevents tube damage or breakage, which is frequently observed when freezing long tube formats in boxes without ventilation slots
• Easy sample reference thanks to the individual alpha-numeric laser labeled code assigned to each sample location to minimise allocation errors, black labels on light-grey surface provide high-contrast for easy readability, labeling remains permanently for along lifetime in your lab, 5 additional inscription labels on the lid enable user-specific labeling
• Design follows the Eppendorf PhysioCare Concept
• Made of polypropylene (PP) for high stability in freezing applications and smooth opening and closing
• For freezing to -86°C
• Autoclavable (121°C, 20 min)
• Transparent lid for easy and fast sample inspection
