20 mL Freestanding Vials, Blue Cap, Polypropylene Copolymer — Caplugs® Evergreen (240-3519-B80)
These 20 mL freestanding vials from Caplugs® Evergreen are molded from polypropylene copolymer (PPC) and feature a flat-bottom base that stands upright on any benchtop without a rack. Supplied non-sterile and unassembled in a 1000/Bag format, they are sized for high-volume clinical and research workflows including urine culture, molecular specimen collection, and large-volume reagent aliquoting. The blue cap provides an immediately visible color-code for specimen type, batch, or priority within multi-color vial management systems.

Applications
- Urine culture and urinalysis — the 20 mL volume accommodates generous collection without specimen insufficiency
- Molecular specimen collection and storage for DNA, RNA, and PCR-based assays
- Reagent aliquoting and buffer preparation where a stable, self-supporting vial eliminates rack dependency
- Large-volume sample archiving and multi-analyte specimen banking
- Environmental and industrial sample collection requiring a chemically compatible, labeled container
- Color-coded sample management systems where blue caps designate a specific specimen type, assay batch, or department
- LIMS barcode scanning workflows — the smooth vial body surface accepts standard labels for direct vial identification and lot traceability

Frequently Asked Questions
Are these vials sterile?
No — the 20 mL freestanding vials are supplied non-sterile. They are intended for general clinical chemistry, urinalysis, molecular specimen handling, and reagent storage applications that do not require a sterility guarantee.
Do the vials come pre-assembled with caps attached?
No — the 1000/Bag pack is supplied unassembled, meaning vials and caps are packaged separately. This format reduces bulk during shipping and storage and is standard practice for high-volume lab consumable procurement.
What does the blue cap indicate in a color-coded system?
Cap color assignment varies by laboratory protocol. The blue cap is commonly used to designate a specific specimen type, assay batch, or departmental priority within a multi-cap-color vial management system. Facilities should map cap colors to their own SOPs and LIMS configurations.
Can these vials be autoclaved for reuse?
Polypropylene copolymer has general autoclave tolerance, but these vials are supplied non-sterile and are designed as single-use consumables. Reprocessing for clinical specimen use is not recommended and may compromise regulatory traceability requirements.
