​Cap assembly includes a seamless liner with premolded C-Flex® fill and vent tubes to create an unobstructed fluid path. The 18" fill tube is plugged at the terminal end to maintain sterility until use. Vent tube includes a 0.2-micron PTFE vent filter to prevent infiltration by contaminants. Vent filter is hydrophobic to guard against loss of costly product or media during filling or emptying. The one-piece liner eliminates the risk of bacterial entrapment and contamination and forms an elastomeric seal between cap and bottle rim.

• Secure, single-piece cap/tubing assembly eliminates contamination and product loss due to lose connections

• Assemblies are pre-sterilized by gamma irradiation—eliminates labor and validation costs associated with assembly and cleaning
