20 mL Freestanding Vials with White Caps — Polypropylene Copolymer, Non-Sterile, 1000/Bag (240-3519-W80)
These 20 mL polypropylene copolymer freestanding vials from Caplugs® Evergreen feature a stable flat-bottom base that stands upright on the bench without a rack, white caps for color-coded specimen identification, and are supplied non-sterile and unassembled in a 1000/Bag format. Part number 240-3519-W80 is well suited for high-volume clinical, environmental, and research workflows — including urine culture, swab transport, molecular specimen banking, and multi-analyte archival storage — wherever a large-capacity, self-supporting vial is needed. The label-compatible exterior surface supports direct-to-vial labeling and LIMS barcode scanning for full lot traceability.

Frequently Asked Questions
Are these vials sterile?
No — they are supplied non-sterile. For applications that require sterile vials, a separately sourced sterile format should be selected. For general specimen collection, aliquoting, and storage workflows where sterility is not a requirement, these non-sterile vials are fully appropriate.
Do the vials need a rack or tube holder to stand upright?
No. The flat-bottom freestanding base allows the vials to stand independently on any bench surface, eliminating the need for external racks during collection, processing, capping, labeling, and storage steps.
How does the white cap support specimen management workflows?
White is a distinct, high-visibility cap color that integrates into multi-cap-color vial coding systems. Labs commonly assign cap colors to specimen type, assay batch, processing priority, or storage condition, and white provides a clean neutral option with excellent label contrast for printed or handwritten identification.
Are these vials compatible with LIMS barcode scanning?
Yes — the natural vial body provides a smooth, label-compatible exterior surface that accepts printed barcode labels for direct LIMS integration, enabling full lot and specimen traceability in clinical and research laboratory information systems.
