BAG PORTS, PORT PLATES,
& PORT DISCS

Bag ports, also known as port plates or port discs, are designed to be ultrasonic or thermal welded to medical and bio-reactor bags of like material. These single-use bags transfer drug compounds, cell culture, fermentation, and other fluids in the biopharmaceutical industry. In a laboratory environment, Port Discs control fluid management. These fittings have also found their way into agricultural applications. Barb sizes range from 1/8″ to 1″.

Available Materials

E8402
A POE copolymer that offers excellent performance as it is durable and flexible. Parts molded in this material provide high clarity. The material’s low density can reduce the weight of end products. E8402 is the perfect material for bag ports as the port will curve with the bag film rather than being a rigid material working against the bag film. The barb will also flex, giving our parts an advantage over other brittle materials that could crack with sideload.

Polypropylene (PP)
Polypropylene is a very versatile material and formulated for biomedical and bioprocess applications. It is radiation stable and is resistant to solvents, chemicals, water and other inorganic environments.
