Sample Integrity Depends on the Freezer Behind It

Years of research, a biobank’s entire sample collection, or a pharmaceutical company’s reference standards can be lost in hours if an ultra-low temperature freezer fails to hold its set point. Eppendorf built its CryoCube line specifically around that risk, engineering ultra-low temperature freezers designed for the temperature stability and recovery performance that irreplaceable samples demand. MediDepot carries the full CryoCube F-Series lineup, giving labs and biobanks a range of capacities within a single trusted ultra-low temperature platform.

What distinguishes this collection is the depth of options within a single, focused product category. Rather than a single freezer size, MediDepot stocks eight CryoCube configurations spanning four capacity tiers, so a lab can match freezer size precisely to its current sample volume and future growth rather than over- or under-buying storage space.

Who Depends on Ultra-Low Temperature Storage

Eppendorf CryoCube ultra-low temperature freezers are built for any organization storing biological samples, reagents, or materials that require deep-freeze stability. This collection is a fit for:

• Research laboratories and academic research departments
• Biobanks and biorepositories managing long-term sample collections
• Pharmaceutical companies storing reference standards and formulation samples
• Biotechnology companies handling cell lines, reagents, and other temperature-sensitive materials
• Hospitals with clinical or translational research laboratories
• Universities running life sciences and biomedical research programs

Inside the CryoCube F-Series Lineup

MediDepot’s Eppendorf collection is built entirely around the CryoCube F-Series ultra-low temperature freezer, offered in four capacity tiers.

Compact Capacity: CryoCube F101h A 36.9" unit with 101 L (3.6 cu.ft.) of capacity, sized for labs with smaller sample volumes or limited floor space that still need dedicated ultra-low temperature storage.

Mid Capacity: CryoCube F440h and F440n Two 37.6" configurations offering 440 L (15.5 cu.ft.) of capacity, suited to labs that have outgrown compact storage but don’t yet need full-size capacity.

Larger Mid Capacity: CryoCube F570h and F570n Two 43.4" configurations offering 570 L (20.1 cu.ft.) of capacity, positioned between the mid and full-size tiers for labs with growing sample collections.

Full Capacity: CryoCube F740h, F740hi, and F740hiw Three 43.7" configurations offering 740 L (26.1 cu.ft.) of capacity, the largest tier in this collection, suited to biobanks and high-volume research labs consolidating large sample collections into fewer units.

All eight models in this collection share a consistent core specification: a single solid door and a documented temperature range of -50°C to -86°C, with door hinge configurations available in both right (7 models) and left (3 models) options across the lineup.

Matching Freezer Capacity to Your Sample Volume

Selecting the right CryoCube model comes down to capacity, floor space, and how your lab’s sample volume is likely to change.

• Current sample volume. Start with your actual current storage need rather than your maximum possible future need, since ultra-low freezers represent a significant capital investment.
• Growth planning. Labs expecting sample volume to grow substantially may want to size up a tier rather than filling a smaller unit to capacity within a year or two.
• Floor space and footprint. Compare unit width (36.9" to 43.7" across this lineup) against your available lab space, particularly in shared cold storage rooms.
• Door hinge orientation. Confirm right- or left-hinge configuration against your room layout and adjacent equipment before ordering, since this affects door swing clearance.
• Consolidation versus redundancy. Some labs prefer several mid-capacity units for redundancy against a single failure, while others prefer consolidating into fewer full-capacity units for easier monitoring.
• Model variant differences. Within a given capacity tier, confirm what distinguishes each variant (such as the F740h, F740hi, and F740hiw) directly on the product page, since specific features can differ between otherwise similarly sized units.

What to Verify Before You Order

Eppendorf CryoCube freezers in this collection are built for the temperature stability that ultra-low sample storage requires. Documented specifications available on the collection page include:

Buyers should confirm current compressor configuration, alarm and monitoring features, and any applicable certifications directly on each product page before ordering, since specific features can vary between model variants within the same capacity tier. MediDepot does not represent that any unit satisfies a specific facility’s regulatory or accreditation requirements; labs should verify equipment against their own sample storage and compliance protocols before purchase.

Comparing the Four Capacity Tiers

Budgeting for Long-Term Sample Storage

An ultra-low temperature freezer is one of the longer-term capital investments a lab makes, so it’s worth planning the purchase with that horizon in mind.

• Size for the next several years, not just today. Sample collections tend to grow, and moving an existing collection to a larger freezer later carries its own risk and labor cost.
• Budget for backup and redundancy. Consider whether your lab needs a secondary unit or backup power plan to protect against a single point of failure, especially for irreplaceable sample collections.
• Plan facility infrastructure alongside the purchase. Confirm your room’s electrical capacity, ventilation, and floor loading can support the unit’s weight and power draw before it arrives.
• Standardize on one platform where possible. Running multiple CryoCube units within the same F-Series simplifies staff training, alarm monitoring, and maintenance procedures.
• Coordinate orders across multiple labs or sites for research institutions or health systems with more than one location, to keep ultra-low storage equipment and protocols consistent.

Frequently Asked Questions

What is the difference between the CryoCube F740h, F740hi, and F740hiw models? 

All three share the same 740 L (26.1 cu.ft.) capacity, 43.7" width, and -50°C to -86°C temperature range, but they are listed as distinct model variants at different price points. Confirm the specific feature differences, such as compressor configuration or monitoring capability, directly on each product page before choosing between them.

What temperature range do Eppendorf CryoCube freezers maintain? 

All eight models in this collection are rated for -50°C to -86°C, the standard ultra-low temperature range used for long-term storage of biological samples, reagents, and other temperature-sensitive materials.

How do I choose between a 440 L and a 570 L model? 

Compare your current and anticipated sample volume against each tier’s capacity, and factor in your available floor space, since the 570 L models are a larger footprint (43.4" wide) than the 440 L models (37.6" wide). If your lab is growing quickly, sizing up may reduce the need for a second purchase later.

Can I choose a left-hinge or right-hinge door configuration? 

Yes, this collection includes both right-hinge (7 models) and left-hinge (3 models) configurations. Confirm which orientation is available for your specific model and capacity tier, and match it to your room layout before ordering.

Are these freezers suitable for a biobank managing a large sample collection? 

The CryoCube F740 series, with 740 L (26.1 cu.ft.) of capacity, is the largest tier in this collection and is well suited to biobanks and high-volume research labs consolidating large sample collections. Confirm specific throughput and monitoring needs against your biobank’s protocols before ordering.

What should I check regarding facility requirements before installing an ultra-low freezer? 

Confirm your room’s electrical capacity, ventilation clearance, and floor loading can support the unit’s power draw and weight. Ultra-low temperature freezers generate significant heat during operation and require adequate airflow around the unit to perform reliably.
