Ready-to-Use (RTU) | Aluminum Crimp Seals | Pharmaceutical Vial Closures

Cyralux™ 20 mm Sterile FLIP TOP Vial Seals are ready-to-use aluminum and polypropylene closures designed for pharmaceutical vial sealing and aseptic fill-finish operations.

Each seal features a one-piece lacquered aluminum shell with a preassembled white polypropylene FLIP TOP button. The button removes to expose the rubber stopper for needle access, while the aluminum skirt remains crimped around the vial neck.

Supplied cleaned, sterilized, and packaged in a double sterile-barrier system, these RTU seals eliminate the need for routine in-house seal washing and sterilization before capping, when handled according to the applicable aseptic process.

Designed for Pharmaceutical Fill-Finish Operations

Cyralux™ sterile FLIP TOP seals are intended for use with appropriately dimensioned 20 mm crimp-neck glass vials and compatible serum or lyophilization rubber stoppers.

The aluminum skirt is manufactured with controlled dimensions to support consistent crimp formation and reliable closure assembly.

The white polypropylene button provides a recognizable closure color for pharmaceutical product identification and packaging operations.

Technical Specifications

Vial and Stopper Compatibility

These 20 mm FLIP TOP seals are dimensioned for standard 20 mm crimp-neck pharmaceutical vials and appropriately sized serum or lyophilization stoppers.

Typical vial formats include 6R, 10R, 20R, and 30R when manufactured with a compatible 20 mm finish.

The complete vial, stopper, and seal combination should be evaluated for dimensional compatibility, crimp performance, and container closure integrity. A nominal 20 mm designation alone does not establish a validated closure system.

Sterile Processing and Packaging

Cyralux™ RTU seals are manufactured in a controlled environment, inspected for defects, and cleaned to specified particulate limits before sterilization.

The seals are supplied in double sterile-barrier packaging for staged introduction into aseptic manufacturing environments.

The supplied technical documentation identifies gamma irradiation or steam sterilization, depending on the product configuration and lot. Customers should confirm the applicable sterilization method using the accompanying lot documentation.

Applications

• Pharmaceutical liquid fill-finish operations

• Lyophilized pharmaceutical products

• Biologics and vaccine packaging

• Clinical trial and small-batch manufacturing

• Isolator and RABS capping operations

• Pharmaceutical manufacturing facilities requiring sterile vial closures
