DURAN® SCREW CAP GL 45 WITH 2 HOSE CONNECTORS FOR LABORATORY GLASS BOTTLES The cap connection system has been specially developed for the easy connection of flexible tubing to the DURAN® GL 45 bottles. Possible biotech applications include the transfer of sterile media from one container to another using a peristaltic pump. The two polyproplylene through connectors have angled top and straight underside connectors. The cap is ideal for use with soft elastic tubing that has an inner diameter of 6 – 9 mm (Viton®, Tygon®, silicone). An optional venting connector is available with, or without a syringe filter. Benefits: • Highly versatile as the screw cap is based on the standard GL 45 thread • Grey polypropylene cap center rotates freely, allowing the bottle to be unscrewed without the need to disconnect the tubing • The angled top connectors prevent kinks in the tubing • Temperature resistant up to +140 °C • Fully autoclavable / dishwasher-proof
