Product Description
Connecting silicone tubing to a bottle should not mean disconnecting it every time the bottle is opened. This two-port cap has a freely rotating center, so the bottle can be unscrewed while tubing stays attached and untangled.
This listing is for DURAN catalog number 1129825: Connector (5.8 mm) and Syringe Disk Filter (0.2 µm), for GL 45 screw cap, with 2-hose connector, Pack of 2. The polypropylene cap fits the standard GL 45 thread and uses an EPDM gasket for a gas-tight seal, holding positive pressure up to about 5 bar in hydraulic testing. Two hose barbs accept silicone tubing for liquid transfer. A matching connector with a 0.2 micron syringe disk filter is available for venting. The cap is autoclavable at 121 C and lab-washer safe. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
