PPC construction is specifically chosen over standard PP homopolymer because it retains flexibility and crack resistance at cryogenic temperatures where homopolymer PP becomes brittle. Each 1,000-vial bag ships with lot number and manufacturing date to satisfy CAP, CLIA, and ISO 15189 traceability requirements. LabSupplies.com is an authorized Caplugs® Evergreen dealer and ships from USA inventory, ensuring consistent domestic supply without offshore lead-time risk.
