Heathrow Scientific Cube Tube Rack Multi-Size Interlocking - Autoclavable - Pack of 5

When samples span multiple tube sizes, a standard tube rack forces a choice: pick the rack for the largest tube and leave the small ones rattling, or use multiple racks and try to keep them aligned. The Heathrow Scientific HS29050A Cube Tube Rack solves this differently — its cube geometry allows multiple tube sizes to sit at the same working height on the same bench plane, with racks interlocking side-by-side to expand the working area.

Each cube accommodates tubes from 0.5 mL microcentrifuge up through 50 mL conicals in its various well positions — multi-size work stays organized on a single plane without separate rack heights creating pipetting access problems. Autoclavable polypropylene. Pack of 5 assorted colors (Blue, Green, Yellow, Orange, Pink) for color-coding by experiment or user.

Features and Benefits

• Same-Plane Multi-Size Format: The cube geometry puts different tube sizes at the same working height — pipette access is consistent across all tube sizes without adjusting technique for rack depth.

• Interlocking Design: Cubes interlock side-by-side to build a larger working array — combine multiple cubes to create a contiguous working surface for large sample sets.

• Wide Tube Compatibility: Multiple well positions accommodate tubes from 0.5 mL microcentrifuge through 50 mL conical in a single rack unit.

• Autoclavable PP: Standard autoclave-compatible polypropylene — sterilize for clean room and sterile processing applications.

• 4.3 × 4.3 × 4.5 in Compact Cube: Designed for lab bench and biosafety cabinet use — does not dominate bench space per cube, and interlocking allows scaling to the work surface size.

• Pack of 5 Assorted Colors: Blue, Green, Yellow, Orange, Pink — identify experiments, users, or sample status by rack color.

Laboratory Applications

• Multi-size tube workflow management where samples span from microcentrifuge to conical tubes within a single protocol step

• Genomics and NGS library preparation where 0.2 mL, 1.5 mL, and 15 mL tubes are all used in the same protocol on the same bench

• Shared lab environments where interlocking cubes allow each user to own their own cube while working on a combined bench surface

• Teaching labs running multi-size protocols where all tube formats need to be visible and accessible simultaneously

Frequently Asked Questions

What well positions does the Cube Rack have?
The Cube Rack has multiple well types for different tube sizes — typically 2 wells for 50 mL, 8 for 15 mL, 6 for 1.5/2.0 mL, and 10 for 0.5 mL per cube. Exact well counts may vary — check the product data sheet for the current well configuration.

How do the cubes interlock?
The side faces of each cube have interlocking geometry that snaps adjacent cubes together when placed side-by-side. Interlocked cubes move as a unit on the bench, preventing drift between individual racks during active pipetting use.

Is this different from the Rota-Rack?
Yes — the Cube Rack (HS29050A) has fixed wells in multiple sizes in a cube format. The Rota-Rack (HS29040B) uses twist-adjustable rotating modules that change the well size for each module independently. The Cube Rack is better when you need multiple tube sizes fixed in place simultaneously; the Rota-Rack is better when you need to change the tube size configuration of a module during a workflow.

Quality Assurance

Heathrow Scientific HS29050A Cube Racks are manufactured from autoclave-compatible polypropylene with verified interlocking geometry for stable multi-cube configuration. Colors are applied during molding for permanent color identification throughout the rack service life.
