7.0 mL Transport Vial Caps — Polypropylene Copolymer, Natural, Unassembled (240-3007-080)
These 7.0 mL polypropylene copolymer (PPC) transport vial caps are supplied non-sterile and unassembled in 1000/Bag packaging, making them an economical bulk solution for high-volume specimen transport and collection workflows. The natural (clear) cap color supports visual confirmation of a secure seal before transport and enables color-coded specimen differentiation across collection protocols. PPC construction delivers exceptional toughness and chemical resistance, keeping specimens safely contained through the mechanical stresses of routine courier and in-house transport.

Frequently Asked Questions
Are these caps sterile?
No — the caps are supplied non-sterile. For workflows requiring sterility, verify whether your collection protocol necessitates a sterile-packaged alternative before ordering.
What does "unassembled" mean for this product?
Unassembled means the caps are packaged separately from the vial bodies, allowing labs to purchase caps and tubes independently and assemble them as needed — reducing per-unit cost when only one component requires replenishment.
Why choose a 7.0 mL vial over a standard 5.0 mL format?
The larger 7.0 mL volume is particularly useful for urine, cytology, stool, and liquid biopsy collections where a single vial must yield enough specimen for multiple downstream laboratory tests without a second collection event.
Is PPC compatible with common specimen preservatives?
Polypropylene copolymer offers excellent resistance to aqueous solutions, dilute acids, dilute bases, and methanol, making it well suited for most standard preservatives and fixatives. For concentrated organic solvents such as ethyl acetate or aromatic compounds, PPC is not recommended — consult your reagent compatibility data before use.
