Technical Narrative
The Caplugs® Evergreen 222-3010-02N is a Sterile HDPE Natural Screw Cap compatible with Caplugs Evergreen transport vials (222-3003/3005/3007 series) and 15 mL conical centrifuge tubes, packaged 1000/Bag. Bulk screw cap supply addresses the practical need in high-volume labs for replacement caps and for labs that purchase vials and caps separately to optimize inventory management. The 1000/Bag format provides cap supply proportional to the high daily cap consumption in specimen transport and aliquoting workflows.
High-Density Polyethylene (HDPE): low extractables, excellent chemical resistance across aqueous and mild organic matrices, secure threading for reliable leak-resistant seal. BPA-free, phthalate-free, FDA-compliant,
Procurement economics: $76.39/Bag (1000 caps), $0.0764/cap. Compatible vials and tubes: 222-3005-070 (5.0 mL HDPE Transport Vials 25/Bag); 222-3005-08K (5.0 mL PPC Transport Vials 1000/Bag); 222-2449-G5K (15 mL PS Conical Centrifuge Tubes 25/Bag). LabSupplies.com ships from USA inventory, typically same business day.

HDPE Screw Cap Compatible Applications
The HDPE screw cap is compatible with the following Caplugs Evergreen vials and tubes requiring a replacement or bulk cap supply.
| Application | Setting / Configuration | Notes |
|---|---|---|
| Transport vial capping | Cap onto 222-3005/3007 series transport vials | HDPE: leak-resistant threaded seal for specimen transport |
| 15 mL conical capping | Cap onto sterile 15 mL centrifuge tubes | Same thread; HDPE cap for re-sealing after centrifugation |
| Bulk cap inventory | High-volume specimen processing lab | 1000/Bag: matches high daily cap consumption |
| Replacement caps | Replace damaged or missing caps on vials/tubes | Purchase separately for inventory buffer |
| Separate vial+cap procurement | Order 222-3005-08K vials + caps | Flexible inventory management for high-volume labs |
| Secondary closure | Seal previously opened specimen vials | HDPE sterile cap for re-sealing stored specimens |
| Dual-use stocking | One cap SKU for two tube types | Single SKU covers both transport vials and 15 mL conicals |
Chemical Resistance — High-Density Polyethylene (HDPE)
Compatibility reference for HDPE at typical laboratory conditions.

Clinical & Research Laboratory Applications
Caplugs® Evergreen sterile HDPE natural screw caps serve clinical diagnostics, reference laboratories, and specimen transport kit manufacturers requiring bulk sterile cap supply compatible with both transport vials and 15 mL centrifuge tubes. High-volume specimen processing labs that consume thousands of transport vials per day benefit from purchasing caps in 1000/Bag bulk format separately from vials — enabling independent inventory management for caps and vials based on actual consumption rates rather than fixed kit ratios. Labs running the 5.0 mL PPC vial in 1000/Bag format (222-3005-08K) use the cap as the complementary 1000/Bag cap supply. The dual compatibility with both transport vials and 15 mL sterile conical centrifuge tubes means a single cap SKU covers multiple tube types in the lab inventory, reducing SKU proliferation.

Frequently Asked Questions
Are the screw caps sterile?
Yes. Sterile — packed 1000/Bag.
Which transport vials and centrifuge tubes are these caps compatible with?
The HDPE cap is compatible with the Caplugs Evergreen 222-3003/3005/3007 transport vial series and 15 mL sterile conical centrifuge tubes (222-2448/2449/2469/2470 series). Verify thread compatibility with any non-Caplugs Evergreen tubes before standardizing.
Why purchase caps separately instead of buying assembled vials?
Separate cap procurement allows independent inventory management when vial and cap consumption rates differ — for example, when reusing vials is not applicable but cap replacement rate differs from vial consumption. It also enables high-volume labs using the 1000/Bag vial format (222-3005-08K) to match cap supply to vial supply at the same 1000-unit pack size.
