Research Laboratory Applications\u003c\/h2\u003e \u003cp\u003eCaplugs® 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.\u003c\/p\u003e \u003ch2\u003eU.S. Manufacturing, Quality \u0026amp; Institutional Procurement\u003c\/h2\u003e \u003cp\u003eCaplugs® Evergreen products are manufactured in the United States under ISO 9001 quality management from FDA-compliant, food-contact-grade resins.
