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

Ready To Use

Mycap® is preassembled, ready to use and single-use. Integral tubing with useful connection options makes aseptic fluid handling in bottles simple. Save time and improve your process by skipping cleaning and assembly.

Quality Components

All Mycap® have our robust, plasticizer-free, platinum-cured silicone seal. Silicone is well recognized as a high-performance closure resin which prevents contaminants from getting in and maintains a microbial barrier across a wide temperature range (including autoclave).

Universal Closure

Mycap® is the first universal closure system – Mycap® Bottle Closures 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.
