7.0 mL Lavender-Cap Screw-Top Transport Vials — Polypropylene, Unassembled, 1,000/Bag (240-3007-L60)
These 7.0 mL polypropylene transport vials are paired with lavender screw caps that follow the CLSI H3 color-coding convention for EDTA anticoagulant applications, making them the standard choice for hematology specimen collection, including CBC, differential count, and ESR workflows. Supplied unassembled — 1,000 vials and 1,000 caps per bag — the format supports pre-labeling and barcode application before capping, which is the preferred workflow for centralized specimen management programs. These non-sterile vials are manufactured from virgin polypropylene and ship ready for immediate integration into high-volume collection and transport programs.

Applications
- Hematology specimen collection: The 7.0 mL volume provides sufficient sample for CBC, differential count, and ESR analysis plus archive aliquots, with minimal dead volume.
- Blood bank transport: Suitable for EDTA and ACD whole blood and serum aliquots; lavender cap color follows the CLSI H3 convention for immediate staff recognition.
- Clinical chemistry: Serum, plasma, and urine analyte transport where PP's broad chemical compatibility with standard clinical preservatives is required.
- Molecular diagnostics: DNA/RNA transport in EDTA-stabilized samples; the 7.0 mL capacity accommodates pre-PCR aliquoting and archival protocols.
- Toxicology and drug screening: Urine chain-of-custody and serum drug-level transport, where a secure threaded screw cap is essential for leak-free handling.

Frequently Asked Questions
Are these vials sterile?
No — the 240-3007-L60 is supplied non-sterile. For most specimen transport and storage workflows, non-sterile vials are standard practice, but if your protocol requires a sterile container, please confirm with your laboratory director before use.
Why does the lavender cap color matter?
Lavender is the universally recognized color convention for EDTA anticoagulant tubes under CLSI H3 and ISO 6710. Using a lavender-capped vial allows phlebotomists, lab technicians, and receiving staff to identify tube type at a glance, reducing the risk of pre-analytical error without additional retraining.
Why are these vials supplied unassembled?
The unassembled format allows labs and specimen-processing centers to apply labels, barcodes, or pre-printed identifiers to the vial body before capping — the preferred workflow for centralized and automated specimen management systems. Vials and caps are packed together in the same 1,000-count bag.
Is polypropylene compatible with EDTA and standard hematology preservatives?
Yes. Polypropylene has excellent resistance to EDTA, ACD, citrate, and standard aqueous clinical preservatives. It is also autoclavable and maintains dimensional stability across a broad temperature range, making it suitable for both specimen transport and frozen storage workflows.
