10–15 mL Centrifuge Tube Storage Boxes, PPC, Green, Eppendorf/Thermo Fisher Compatible — 240-6615-G3D | 2/Bag | Caplugs® Evergreen

15 mL Centrifuge Tube Storage Boxes, 36-Position — Polypropylene (PP), Green, 2/Bag

Technical Narrative

The Caplugs® Evergreen 240-6615-G3D is a 36-position 15 mL centrifuge tube storage box precision-molded from virgin Polypropylene (PP) for organized benchtop staging, freezer storage, and transport of standard 15 mL conical centrifuge tubes. The 36-well grid holds each tube upright in a defined position — eliminating the tube-tipping, label-obscuring, and cross-contamination risks of loose tube storage in drawers or trays. The green PP construction enables color-coded tube batch management: green signals safety or completed-status tube management in color-coded laboratory workflow systems. Autoclave and UV-compatible for clean-bench and BSL-2 environment workflows.

The box geometry is engineered for the 15 mL conical OD (17 mm) to provide positive tube retention without excessive force — tubes seat cleanly by gravity and release without tool assistance during high-throughput pipetting workflows. PP construction withstands ‑20°C frozen storage for biorepository and biobank tube archiving, and autoclave decontamination at 121°C before reuse or disposal. The flat base allows stacking of loaded boxes to maximize freezer shelf density in biorepository environments.

At $20.81 per 2/Bag — $10.4025 per box — the delivers organized 15 mL tube storage at a per-box cost that supports single-use-per-batch allocation for experiment tracking without reuse overhead. Also available: 240-6630-E3D (30 mL / 16-position / Orange, $21.41/Bag) — enabling matched procurement across both 15 mL and 30 mL conical formats from a single vendor.

Technical Specifications — Caplugs® Evergreen

Compatible Tube Formats —

The is precision-dimensioned for 15 mL conical centrifuge tubes. Verified compatible formats:

Tube OD must match the box well diameter. Always validate with a sample box before bulk purchase if using non-standard tube formats.

Chemical Resistance — Polypropylene (PP)

The is molded from virgin Polypropylene (PP). PP provides excellent chemical resistance for lab disinfectants, autoclave compatibility, and UV decontamination stability.

Clinical & Research Laboratory Applications

The 15 mL centrifuge tube storage box serves molecular biology and genomics labs organizing extraction batches and NGS library prep tube sets; biobank and biorepository programs requiring organized ‑20°C and ‑80°C tube archiving; clinical reference labs managing specimen aliquot sets for reflex testing panels; pharmaceutical downstream processing requiring organized tube staging; cell culture labs managing harvest and pelleting tube batches; and any laboratory workflow requiring upright, labeled 15 mL tube storage with defined well positions for sample tracking.

Frequently Asked Questions — Caplugs® Evergreen

What centrifuge tube formats fit the storage box?

The is dimensioned for standard 15 mL conical centrifuge tubes with 17 mm OD — the universal format across Thermo Fisher (Falcon®), Corning, Eppendorf®, and generic brands. The Caplugs® Evergreen 240-2448 (PS) and 240-2469 (PPC) tube families are verified fits. Request a free sample to validate fit before bulk purchase.

Can the box be stored in a freezer?

Yes. The is molded from PP which maintains structural integrity at ‑20°C for standard biorepository frozen storage. For ‑80°C ultra-low temperature storage, confirm PP cold-temperature performance with your specific protocol before bulk commitment. The flat-base stacking geometry maximizes freezer shelf density when multiple boxes are stored in the same drawer.

Are the storage boxes BPA-free?

Yes. Molded from virgin Polypropylene (PP) containing no BPA and no phthalate plasticizers — suitable for clinical, research, and regulated laboratory sample storage environments.
