About this item
Provides an aseptic seal for transferring high-purity fluids
Eight configurations permit precise matching of Top Works components to bottles and carboys. Polypropylene closures have center holes. They are modified to clamp a silicone stopper onto the bottle or carboy, creating a primary elastomeric seal. High-purity, platinum-cured silicone tubing ensures the fluid contact areas are crevice-free, which helps eliminate cross-contamination.
Materials are food-grade and noncytotoxic. Complies with U.S.P. Class VI requirements. Autoclavable.
For use with 125 mL to 50 L plastic bottles and carboys.
