The MYCAP® Bottle Closure Family

MYCAP® closures are a one-piece, ready-to-use and single-use aseptic fluid transfer system for bottles.

Select from a diverse range of standard configurations purposefully designed for common applications. Or, capitalize on the generous design freedom and ever-expanding range of bottles to configure MYCAP® to your application specification.

Remarkably, the robust platinum-cured silicone seal never changes from design to design, despite the range of capabilities. MYCAP® is the first truly universal closure system.

MYCAP® expands capabilities, removes uncertainty and eases validation.
