Applications
- Large-volume urine culture collection and transport where smaller vial formats risk specimen insufficiency
- Swab transport medium elution and environmental specimen collection requiring generous headspace
- Molecular specimen banking — DNA, RNA, and genomic material storage in PPC-compatible format
- Reagent aliquoting and multi-analyte archival storage with stable bench-top placement
- Color-coded specimen management using lavender caps to differentiate specimen type, assay batch, department, or processing priority
- LIMS integration and barcode scanning workflows — the flat label-compatible surface supports direct-to-vial labeling
- CAP, CLIA, and ISO 15189 environments where lot-numbered consumables support traceability requirements

Frequently Asked Questions
Are these vials sterile?
No — they are supplied non-sterile and unassembled. For workflows requiring sterile containers, a separate sterile-grade vial should be selected.
Do the vials need a rack to stand upright?
No. The flat-bottom freestanding base allows these vials to stand independently on any bench surface, eliminating the need for tube racks during collection, processing, capping, and labeling steps.
What does the lavender cap color signify?
Lavender is commonly associated with EDTA specimen types in standard laboratory color-coding conventions and can also be used to designate a specific specimen type, assay batch, department, or processing priority within a multi-cap-color vial system — the specific meaning is defined by each laboratory's internal protocol.
Are these vials compatible with LIMS barcode scanning and direct labeling?
Yes. The smooth natural-colored vial body provides a label-compatible surface suitable for printed barcode labels, thermal-transfer labels, and direct-to-vial labeling systems used in LIMS-integrated workflows.
