Closures and Stoppers

These closures and stoppers ensure aseptic fluid transfer, sealing, filling and sampling for containers used in pharmaceutical and biopharmaceutical processing. Manufactured from a platinum-cured silicone that is free of animal-derived ingredients, the closures meet USP (United States Pharmacopeial) Class VI and FDA standards — i.e., they are biologically safe and suitable for use in pharmaceutical, biomedical and laboratory environments. The closures are designed for carboys, flexible container systems, solution and media bottles, and other vessels, and work well with stainless steel, glass and plastic. Both closures and stoppers are injection-molded in a clean-room environment and have a smooth finish with gap-free surfaces that produce a true seal. This also reduces cross-contamination and offers a secured environment to minimize product loss. Closures can withstand temperatures from –100°F to 400°F.
