Bottle Cap and Stopper Accessories

This category includes stopper accessories for use with perforated stoppers and bottle cap accessories for use with compatible caps. Stopper accessories modify closures, often enabling sterile fluid transfer without extractables, as required by pharmaceutical and biotech applications. These stopper accessories are typically constructed from silicone, making them generally stable, non-reactive, and resistant to a wide range of extreme temperatures and environments; they are generally non-sterile and autoclavable. Bottle cap accessories, such as torque fittings, may be used to support proper sealing and handling.
