7.0 mL Screw-Cap Transport Vials — PPC, Yellow Cap, Unassembled, 1,000/Bag (240-3007-Y80)
These 7.0 mL transport vials are precision-molded from virgin Polypropylene Copolymer (PPC) and paired with a yellow screw cap following the CLSI H3 color-coding convention for ACD (Acid Citrate Dextrose) and SST indicator applications. The semi-translucent PPC tube body allows visual sample monitoring throughout the collection-to-storage chain, while the 7.0 mL volume provides sufficient capacity for initial analysis plus archive aliquots without excessive dead volume. Supplied 1,000 vials and 1,000 caps unassembled per bag, part number 240-3007-Y80 is a practical, high-volume solution for blood bank, molecular diagnostics, and specimen transport programs.

Applications
- Blood bank specimen transport: The yellow cap follows the CLSI H3 convention for ACD-B whole-blood collection tubes, making these vials a natural fit for blood bank workflows where color-coded identification is critical.
- DNA studies, HLA typing, and paternity testing: The 7.0 mL volume provides sufficient sample for molecular analysis plus reserve aliquots, and PPC construction is chemically compatible with standard nucleic-acid preservatives.
- Serum and plasma transport: Yellow is also used as an SST (serum separator tube) indicator in many lab SOPs, supporting clinical chemistry and immunoassay specimen handling.
- Frozen specimen storage: PPC's enhanced low-temperature impact strength makes these vials well-suited for samples destined for −20 °C or −80 °C archival storage following initial analysis.
- Pre-labeled or barcoded specimen management: The unassembled format allows centralized specimen management systems to print, label, or apply barcodes to vials before capping — a preferred workflow for high-throughput collection programs.

Frequently Asked Questions
Are these vials sterile?
No — these vials are supplied non-sterile, which is appropriate for most specimen transport and storage applications where sterility is not a regulatory requirement. If your workflow requires sterile vials, please contact our team for alternative options.
Why does the yellow cap matter for blood bank and clinical labs?
Yellow is the CLSI H3 color-coding convention for ACD (Acid Citrate Dextrose) tubes and is also used as an SST indicator in many institutional SOPs. Using color-coded vials that match your analyzer or phlebotomy workflow helps reduce identification errors and supports compliance with your lab's standard operating procedures.
Why are the vials and caps shipped unassembled?
The unassembled format gives high-volume labs the flexibility to pre-print labels, apply barcodes, or sort vials before capping — a preferred workflow for centralized specimen management and automated accessioning systems. Each bag contains exactly 1,000 vials and 1,000 caps.
What advantage does PPC offer over standard polypropylene for frozen storage?
Polypropylene Copolymer (PPC) retains greater impact strength at low temperatures compared to standard PP homopolymer, reducing the risk of cracking or breakage when vials are handled at −20 °C or −80 °C. This makes these vials the preferred choice when samples will be archived in ultra-low-temperature freezers after initial analysis.
