Heathrow Scientific Transformer Cube Tube Rack 15 & 50mL - -80°C Rated - Pack of 5

Storing 15 mL and 50 mL conical tubes takes disproportionate bench space compared to their volume — a single 50-position 50 mL conical rack occupies as much bench area as most other tube rack types combined. The Heathrow Scientific HS23271A Transformer Cube Tube Rack eliminates this problem: the cube body opens, reconfigures, and closes to hold either 50 mL or 15 mL tubes in a vertical stacking orientation that minimizes bench footprint.

With a -80°C temperature rating, the Transformer Cube is also suitable for cryogenic freezer organization — one of the few conical tube racks rated for long-term ultra-low temperature storage. Purple polypropylene. Pack of 5. 9 wells for 15 mL, 16 wells for 50 mL tubes.

Features and Benefits

• Transforms Between 15 mL and 50 mL Configuration: The cube body opens and reconfigures to switch between the 16-well 50 mL format and the 9-well 15 mL format — one rack serves both common conical tube sizes.

• -80°C Rated: Maintains structural integrity and well geometry in ultra-low temperature freezers — suitable for long-term cryogenic sample storage in both 15 mL and 50 mL tube formats.

• Compact Cube Footprint: 5.3 × 5.3 × 5.1 in cube geometry stacks vertically — more storage capacity per bench area than flat-format conical racks.

• Autoclavable Polypropylene: Sterilizable for clean room and sterile processing environments.

• Pack of 5, Purple: Five racks per pack — color coding for workflow organization in labs with multiple rack types.

Laboratory Applications

• Ultra-low temperature (-80°C) sample storage for 15 mL or 50 mL conical tubes where a cryogenic-rated rack is required

• Compact storage of 50 mL conical tubes in vertical format when bench or freezer shelf space is at a premium

• Large-scale cell banking and biorepository workflows where 15 mL conical tubes are stored in freezers alongside 50 mL tubes in matching rack formats

• Sample processing workflows that transition between 15 mL and 50 mL tubes within the same protocol step, using the transformer configuration to accommodate both sizes

Frequently Asked Questions

Is HS23271A the only conical tube rack rated for -80°C freezer use?
It is one of a small number of polypropylene racks specifically rated to -80°C. Many standard tube racks are not rated below -20°C or -40°C. If your application requires ultra-low temperature storage for conical tubes, verify your rack is rated for the storage temperature before use.

How does the transformation between 15 mL and 50 mL work?
The cube body sections open on hinged panels that reconfigure the internal geometry from 50 mL well positions to 15 mL positions. Instructions are included with the rack. The transformation takes seconds and requires no tools.

Can I use this in a standard benchtop centrifuge?
The Transformer Cube is a storage and staging rack, not a centrifuge carrier. Remove tubes from the rack before centrifugation. The -80°C rating applies to static storage, not centrifuge conditions.

Quality Assurance

Heathrow Scientific HS23271A Transformer Cube Racks are manufactured from polypropylene tested for structural integrity at -80°C and autoclave temperatures. The transformation mechanism is designed for repeated opening and reconfiguration without hinge fatigue under normal lab use.
