Mega Racks® Tube Rack for 10-13mm Tubes

Mega Racks® Polypropylene Tube Rack for 10–13mm Tubes

Heathrow Scientific Mega Racks® are the high-capacity tube rack solution for clinical, diagnostic, and research laboratories processing large sample volumes daily. Designed for 10–13mm outer diameter tubes — including standard 5mL and 7mL collection tubes, small culture tubes, and ESR tubes — Mega Racks deliver organized, alphanumeric-indexed storage in a fully assembled, no-tools-required polypropylene construction. The single-well format holds 216 tubes in a compact footprint; the double format links two rack sections for 432-tube capacity on a single bench station.

Specifications

Features & Benefits

• 216-well or 432-well capacity: The single format (216 wells, 33.7 x 23.5 x 9.1 cm) handles a full processing run on a standard bench. The double format (432 wells, 67.3 x 23.5 x 9.0 cm) doubles capacity without requiring a second rack footprint, ideal for high-throughput clinical labs processing continuous batches.
• Alphanumeric position identification: Row and column coordinates are molded directly into the rack surface, enabling precise tube location recording in laboratory information systems and eliminating position transcription errors in high-volume processing.
• Polypropylene construction: Chemical resistance to the dilute acids, bases, and disinfectants used in routine laboratory cleaning. Fully autoclavable for sterilization between specimen types or study cohorts.
• Fully assembled and ready to use: No assembly required. Each rack ships in the configuration shown — no separate inserts, pins, or alignment steps needed before loading tubes.
• Sturdy, stable base: Flat polypropylene base resists sliding on bench surfaces during high-speed pipetting and provides a stable platform for transport between workstations.
• Color-coded options: Available in Blue and White to visually distinguish tube sets by project, specimen type, priority level, or processing stage in multi-user environments.
• Open-side design: Open lateral walls allow tube labels to be read without removing tubes from the rack, reducing handling and maintaining chain-of-custody during processing.

Applications

Mega Racks® 10-13mm racks are the workhorse storage solution in high-throughput clinical chemistry and hematology labs where large daily sample volumes make compact, organized tube staging essential. Blood bank and coagulation labs use them to stage 5mL and 7mL ESR tubes, serum separator tubes, and EDTA tubes through multiple analyzer access points without repositioning samples between instruments. In research settings, these racks organize primary culture tubes, cryovial prep tubes, and spin-column eluates during large-cohort experiments where the 216-well or 432-well capacity eliminates the rack-swapping interruptions that disrupt workflow in smaller-format racks. Environmental monitoring labs processing large numbers of small culture tubes for water quality analysis use the double format to stage a full day's run in a single rack structure, reducing bench reorganization time between batches. The open-side design is particularly valued in these settings because tube barcodes remain visible throughout the workflow without manual tube handling.

Frequently Asked Questions

What tube types fit in the Mega Racks® 10-13mm format?

The 10-13mm well diameter accommodates tubes with outer diameters between 10mm and 13mm. Common compatible tubes include standard 5mL Vacutainer-style blood collection tubes (12mm OD), small culture tubes (10-12mm OD), ESR sedimentation tubes, and microcentrifuge tubes in upright orientation when used with an insert. Always verify your specific tube outer diameter against the 13mm maximum before ordering, as some manufacturer variations can cause fitment issues with tubes at the upper end of the range.

What is the difference between the single and double Mega Rack® format?

The single-format rack holds 216 tubes in a 33.7 x 23.5 cm footprint — the standard choice for moderate-throughput labs or where bench space is limited. The double-format rack holds 432 tubes in a 67.3 x 23.5 cm footprint — effectively two single racks joined end-to-end in a single rigid structure. The double format is designed for high-throughput labs processing 300+ samples per run, where a single large rack is easier to manage than two separate racks that can shift independently during batch processing.

Can Mega Racks® be autoclaved between specimen types?

Yes. Polypropylene construction supports standard autoclave sterilization cycles. The fully assembled, single-piece design has no internal components that trap moisture or resist drying, making autoclave turnaround fast. After autoclaving, allow the rack to cool completely before loading temperature-sensitive specimens. For labs processing infectious materials, the smooth polypropylene surface also supports surface decontamination with 10% bleach or 70% ethanol between runs without material degradation.
