Sartorius' Mycap® Bottle Closures make aseptic fluid transfer into and out of bottles simple and reliable.

Dip Tube Tip

Tubing ports on Mycap® feature our dip tube tip. The polypropylene component prevents the tube from becoming stuck or suctioned to the wall or bottom of the bottle during fluid removal. The subtle saddle shape ensure liquid is transferred out, down to the very last drop.

Universal Closure

All Mycap® have our robust, plasticizer-free platinum-cured silicone seal. Silicone is well recognized as the high-performance closure resin preventing contaminants from getting in and maintaining a microbial barrier across a wide temperature range including autoclave. Mycap® feature the same seal regardless of bottle type, tubing size, tubing type or port configuration making it simple to validate one and use Mycap® anywhere in your drug production process—Mycap® is the first universal closure system.
