Mycap® Aseptic Bottle Closures
Advancing the Function, Handling and Performance of Plastic and Glass Containers
Do more with centrifuge tubes, bottles, flasks and carboys fitted with a Mycap® closure. Mycap® improves container functionality by integrating tubing with the cap, which provides practical and dependable aseptic fluid handling. The versatile platform makes it possible to adjust the number, size and material of tubes in the cap without compromising the Mycap® high-performance platinum-cured silicone seal, allowing you to configure a system that fits your process applications.
Plasticizer-free, platinum-cured silicone seal maintains closure integrity and retains its physical properties from -65°C to > 200° C.
From the inventive dip tube tip for maximum fluid removal to the QUICKSEAL® aseptic disconnection, Mycap® is an adaptable solution for any application.
Mycap® is built with the same, proven closure system regardless of the container or tubing materials. Validate Mycap® once, and use it freely across the entire production process.

Mycap® silicone closure is plasticizer-free, stabilizer-free and has no antioxidants. The low stress-to-seal design provides a highly compliant and reliable closure with outstanding compression set and low creep properties.Mycap® is an ideal closure for most biopharmaceutical applications.
Purpose-built dip tube tip prevents suction during fluid removal. The subtle saddle shape ensures fluid removal down to the very last drop.
The Z-Flex Articulator is an elegantly simple design that is remarkably effective at keeping fluid inlet lines where they are needed or dip tubes away from other accessories in the bottle.
Quickseal® delivers simple and fast aseptic disconnection. Cut the collar to disconnect a filled bottle and seal the tubing in one simple step. Mycap® closures combined with Quickseal® disconnection provide a reliable system for critical fluid-management processes.

The stainless-steel collar, which is bonded to the outside of the tubing and encased in the silicone seal, is also a non-fluid contact surface.
The polycarbonate threaded closure is a non-fluid contact surface.
The tubing integrated into the cap is also a fluid contact surface.
The platinum-cured silicone seal is one of the fluid contact surfaces of a Mycap® closure.
Mycap® assemblies are well-suited for most biopharma, vaccine or cell and gene therapy applications where closed, aseptic fluid handling is required. Explore below to learn more about the targeted applications for Mycap® single-use assemblies.
Small bottles and centrifuge tubes are ideal for sample collection, and the integral tubing and secure silicone seal of Mycap® prevent contaminations and false positives.

Bottles with Mycap® closures, either singles or manifolds, are the preferred containers for collecting and storing media or buffer. The dip tube tip gets the last drop of media out.
Tubing of a Mycap® closure with dip tube can be aseptically welded or connected to tubing from a bioreactor, providing an aseptically closed feed system to transfer acid, base and other supplements.
Add a Mycap® closure to bottles and flasks equipped with a magnetic stir bar to benefit from aseptic fluid-handling in your small-scale mixing system. Both standalone and fully assembled Mycap® solutions are available.
Add Mycap® to bottles and carboys used for freeze/thaw operations to dramatically improve filling and draining by making each an aseptically closed system and liberating the process from the confines of biosafety cabinet.
A comprehensive portfolio of standard and custom tube sets for transfer, distribution or filling of in-process fluids.
Installed on an array of tube materials, Quickseal® provides reliable and rapid aseptic tube disconnection.
Flexsafe® 2D and 3D single-use bags are designed to store and transport all bioprocessing fluids.
Opta® SFT aseptic tube connectors allow fast and reliable sterile connection and fluid transfer between two pre-sterilized process components.
