Labs pressed for space confront limits of traditional canisters as new designs reshape efficiency and safety
Narrow Neck Dewars Limit Efficiency
IVF cryo storage has long relied on small, narrow neck portable dewars (such as the MVE XC 47/11s or the Taylor-Wharton HC35/38s) that hold only about 180 canes and require manual refilling. To keep pace with rising cycle volumes, labs often multiply these units across crowded rooms or configure them beyond recommended specifications. Both approaches introduce handling risks and slow routine operations.
IVF LABS ARE LOSING SPACE, TIME & CONTROL
Reclaim 80% More Cryo Capacity Without Adding a Single Square Foot
Here’s what you're up against:
Cryo tanks filled to unsafe levels
Manual sample handling prone to human error
No digital trail for chain of custody
Floor space stretched beyond capacity
Cryohexagon’s hexagonal grid racking system can bolster storage capacity several times over, within your existing footprint while enhancing safety, ergonomics, and access. See how other IVF Clinics are saving space while improving control and safety.
The Hexagonal Geometry Advantage
Cryohexagon’s racking system replaces conventional square or unsupported SUC-1 canisters with a hexagonal design. Each canister sits in its own independent cell, reinforced by surrounding walls to prevent shifting when samples are inserted or removed.
This honeycomb-style structure creates a flat working surface at the top of the freezer, allowing embryologists to handle specimens at a safe, ergonomic height while keeping them fully submerged in LN2. By improving canister stability and reducing wasted volume, the hexagonal grid provides a more efficient and secure way to organize cryo storage.
Lab directors report that routine preventive maintenance on larger cryogenic freezers is often a challenge using square canisters such as the SUC-1. Because these square canisters are crammed into a cylindrical vessel and often without defined slots, each one props up the next. The moment one is removed, others can shift — creating unnecessary risk of destabilization and potential loss of critical biological samples.
High-Volume Workload, No Room to Expand
Dr. Roee Sela, former lab director at a leading Israeli IVF Center, managed more than 10,000 treatment cycles each year in a facility that had no space left for additional cryo storage. Conventional methods were at capacity, leaving canisters unstable and sample handling increasingly difficult.
To solve the issue, Dr. Sela developed a hexagonal racking system—now part of Cryohexagon’s platform—that secures each canister independently, seals its contents, and allows for safer, more ergonomic access. The design was created to reduce the operational risks that high-volume labs face when physical expansion is not an option.
Fourfold Capacity in Large Cryogenic Freezers
When installed in large cryogenic freezers, Cryohexagon’s racking system increases capacity up to four times compared to traditional layouts. A freezer that might otherwise store around 600 canes can hold around as many as 2,500 with the hexagonal configuration—consolidating the equivalent of more than a dozen narrow neck dewars into the same footprint.
The platform also offers optional digital tracking through barcodes, RFID, or QR codes. Each insertion and extraction can be logged down to the cell, canister, and goblet level, creating a complete electronic chain of custody. By combining higher-density storage with integrated traceability, Cryohexagon addresses both capacity constraints and procedural vulnerabilities in cryo sample management.
