DURAN 1129817 Connection System Screw Cap GL 45

DURAN 1129817 Connection System Screw Cap GL 45

The DURAN 1129817 Connection System Screw Cap GL 45 enables complex multi-line liquid and gas connections to DURAN GL 45 bottles, supporting simultaneous inlet, outlet, vent, and sampling functions.
Each GL 18 port provides a secure interface for hoses or tubing, while the integrated membrane filter vent balances pressure and maintains sterility during autoclaving or dispensing.

Made from chemically resistant, autoclavable materials, the system offers exceptional durability and reusability in demanding laboratory environments.
The precision-engineered GL 45 thread fits tightly to DURAN bottles, preventing leakage and contamination throughout pressurized or sterile processes.

Because the DURAN 1129817 Connection System is autoclavable up to 121 °C, it supports sterile re-use without loss of integrity or sealing performance.
This four-port configuration is perfect for advanced applications such as media distribution, bioreactor feeding, or gas exchange in controlled environments.
