The DURAN® 4-port connector cap is manufactured using an innovative additive manufacturing method called three-dimensional metal printing. This method allows the complex form to be optimised using computer-aided design software, as well as significantly reducing the amount of metal required for construction. The transfer connection cap can be used with all sizes of DURAN® GL 45 bottles, and facilitates the movement of liquids within a closed and aseptic system. The four male hose connectors are suitable for flexible tubing with a 6.4 mm (1/4") inner diameter. This corresponds to the SDD initiative Size A tubing type, allowing easy connection to buffer bags, mixing systems, etc. Freely rotating stainless steel centre allows the bottle to be unscrewed without the need to disconnect the tubing. Connectors and body are manufactured from Type 316L (1.4404 / S31603) stainless steel. A silicone gasket and the GL 45 screw cap provide a liquid tight seal. Wide temperature usage range (up to 180 °C). Autoclavable (121 °C for 15 minutes). Retrace coded for full traceability. Ideal for chemistry, life science and biopharma laboratories.
