Corning 11500 Transfer Cap with Diptube w 0.2 ul Vent Cap for 5L Flask Case of 4 Caps

Corning 11500 Aseptic Transfer Cap – For 5L Erlenmeyer Flasks, MPC Connector, Sterile

The Corning 11500 is a high-performance aseptic transfer cap designed to convert standard 5L Corning Erlenmeyer flasks into a fully closed system for liquid handling. This disposable, 100 mm cap assembly is engineered to reduce the risk of adventitious contamination during the transfer of cell culture media, buffers, or cell suspensions. The system features a rigid internal polypropylene dip tube that reaches the bottom of the flask for maximum liquid recovery. Externally, the cap is equipped with two ports: a venting port with a 50 mm diameter, 0.2 µm hydrophobic PTFE membrane filter for sterile gas exchange, and a liquid transfer port featuring 1/4" ID heat-sealable, chemically resistant flexible tubing ending in a male plastic coupler (MPC). Individually double-bagged and gamma-irradiated, the 11500 is an essential accessory for GMP-compliant bioprocessing and scale-up applications.

Technical Performance and Design

• Closed System Integrity: Enables the aseptic transfer of fluids via positive or negative pressure, ensuring that the flask contents are never exposed to the external environment during filling or emptying.

• Rigid Polypropylene Dip Tube: The internal dip tube is precision-sized to reach the lowest point of the 5L flask, ensuring nearly complete sample recovery and minimizing dead volume.

• High-Efficiency Venting: The 50 mm vent filter with a 0.2 µm PTFE membrane allows for high-flow gas exchange while maintaining a robust microbial barrier against contaminants.

• Heat-Sealable Tubing: The liquid transfer line is made of flexible, weldable tubing (1/4" ID, 3/8" OD), allowing for seamless integration into existing single-use manifolds and tubing sets.

Key Benefits & Applications

• Aseptic Inoculation & Harvest: Ideal for the sterile addition of seed cultures or the removal of clarified lysates in pilot-scale fermentation and cell culture workflows.

• GMP Manufacturing: The double-bagged packaging is specifically designed for easy entry into cleanroom environments, supporting stringent regulatory requirements for drug development.

• Reduced Contamination Risk: By eliminating the need to "crack" the cap in a laminar flow hood, the 11500 significantly lowers the probability of batch failure due to human error or environmental factors.

• Universal Connectivity: The MPC male disconnect provides a standardized interface for connecting to media bags, bioreactors, or sampling manifolds.
