20 mL Freestanding Vials, Green Cap, Polypropylene Copolymer — Caplugs® Evergreen (240-3519-G80)
These 20 mL polypropylene copolymer freestanding vials feature a flat-bottom base that stands upright without a rack, making them ideal for high-throughput bench-top workflows in clinical, research, and industrial laboratories. Supplied non-sterile and unassembled in 1000/Bag format, part number 240-3519-G80 includes green caps that support color-coded specimen management across multi-department or multi-assay environments. The large 20 mL capacity accommodates generous specimen volumes for applications where smaller formats risk specimen insufficiency.

Applications
- Urine culture and urinalysis — the 20 mL capacity handles standard large-volume collection protocols without risk of specimen insufficiency
- Molecular and nucleic acid specimen collection — polypropylene copolymer is compatible with DNA/RNA preservation buffers and molecular reagents
- Reagent aliquoting and preparation — the freestanding base keeps vials stable during dispensing without requiring a rack
- Large-volume sample archiving and long-term storage in clinical, biobank, and research freezer environments
- Environmental and industrial sample collection where generous vial volume and chemical durability are required
- Color-coded multi-department workflows — green caps visually distinguish specimen type, assay batch, or priority level at a glance
- LIMS and barcode integration — the natural vial body surface accepts labels and is compatible with direct barcode scanning

Frequently Asked Questions
Are these vials sterile?
No — they are supplied non-sterile and unassembled in 1000/Bag packaging. For workflows that do not require sterility, such as routine urinalysis, reagent aliquoting, or sample archiving, the non-sterile format is appropriate and more cost-effective.
Do the vials need a rack to stand upright?
No — the flat-bottom freestanding base allows each vial to stand independently on any level bench surface, simplifying multi-vial processing and reducing the need for additional rack hardware.
Why are the caps green? Can I use these vials with a different cap color?
Green caps are included to support color-coded specimen identification systems, where each cap color designates a specific specimen type, department, or assay batch. The vials are supplied pre-paired with green caps; if your workflow requires a different cap color, Caplugs® Evergreen offers this vial format in multiple cap color options — contact LabSupplies.com for availability.
Are these vials compatible with LIMS barcode scanning?
Yes — the natural polypropylene copolymer vial body accepts standard adhesive labels and is compatible with direct barcode scanning, supporting integration with most laboratory information management systems.
