Product Description
Building a custom fluid path for a wide-mouth bottle no longer means drilling caps or improvising seals. This modular GLS 80 cap provides four GL 18 ports that can be fitted for tubing, filters or blanks, so a single closure adapts to many different transfer and venting tasks.
This listing is for DURAN catalog number 293109103: GLS 80 Screw Cap, with 4 GL 18 ports and O-ring seal, PP/EPDM, blue/grey/white, Case of 2. The polypropylene cap seals with an EPDM O-ring and threads onto any GLS 80 bottle. Changing inserts in the GL 18 ports accommodates tubing of 3.2, 6.0, 8.0, 10.0 or 12.0 mm, and a syringe filter can provide sterile pressure equalization. Unused ports close with blank GL 18 caps. The assembly is autoclavable and ships two per case. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
