DuPont Liveo Pharma Bottle Closures

DuPont Liveo Pharma Bottle Closures are one-piece silicone stoppers and tubings made from biomedical-grade silicone elastomers. They are designed specifically to seal threaded glass and plastic bottles and containers used for critical fluid transfer, media and buffer pooling and storage, and sample collection in biopharmaceutical and biotechnology processes.

The bottle closures include a one-piece silicone seal part made from biomedical-grade platinum-cured silicone elastomer, moulded with high-purity platinum-cured silicone tubing. This makes the product particularly suitable for preventing leak and contamination risk. Both the silicone extruded tubing and moulded parts are constructed with biomedical-grade silicone elastomers formulated and compounded by DuPont to enable high purity by design.

The one-piece silicone seal part is designed to the user’s specific needs and is manufactured and packaged in a strictly controlled clean manufacturing environment. The bottle closures are designed to meet the highest standards in terms of biocompatibility and regulatory requirements and can be sterilised by autoclave and gamma irradiation for use in aseptic environments.

The cured silicone seal parts currently are available for GL45 and 38-430 neck bottles and containers. Silicone tubing is available in Shore A durometers of 50, 65 and 80. A range of tubing lengths and diameters can be accommodated according to the user’s specific needs. The number and dimensions of tubing pieces moulded to the seal part are determined by the closure size. An external polypropylene cap is supplied with the silicone closure assembly.
