7.0 mL Transport Vial Caps, Polypropylene Copolymer — Natural, Pre-Assembled, 1000/Bag (240-3007-08K)
These 7.0 mL transport vials from Caplugs® Evergreen are constructed from Polypropylene Copolymer (PPC) and supplied pre-assembled with a natural cap, non-sterile, in convenient 1000/Bag bulk packaging. The clear PPC tube body allows direct visual inspection of specimen volume and quality before processing, while the natural cap supports color-coded specimen differentiation in multi-vial collection workflows. Designed for the mechanical demands of routine specimen transport — including courier handling, pneumatic tube systems, and centrifuge loading — these vials deliver reliable containment without cracking or leaking.

Frequently Asked Questions
Are these transport vials sterile?
No — they are supplied non-sterile, pre-assembled with the natural cap, in 1000/Bag bulk packaging. Sterile transport vials are required for select microbiology applications; confirm your protocol requirements before ordering.
What is the advantage of the 7.0 mL size over a standard 5.0 mL transport vial?
The 7.0 mL volume format accommodates higher-volume specimen collections — such as urine, cytology, stool, and liquid biopsy — where additional volume is needed to support multiple downstream test aliquots from a single collection vial without requiring a second draw or collection event.
Why is Polypropylene Copolymer (PPC) specified instead of standard polypropylene?
PPC offers enhanced impact toughness and resistance to stress-cracking compared with homopolymer PP, making it better suited to the mechanical stresses of courier transport, pneumatic tube systems, and centrifuge loading where vial integrity is critical.
Can the clear tube body be used to visually inspect specimens before processing?
Yes — the natural (clear) PPC tube allows direct visual assessment of specimen type, volume, and appearance, supporting pre-analytical quality checks before the vial reaches the analyzer or processing bench.
