DURAN 1129818 Connection System Screw Cap GL 45

DURAN 1129818 Connection System Screw Cap GL 45

The DURAN 1129818 Connection System Screw Cap GL 45 provides a five-port configuration for laboratories that demand maximum connection flexibility in closed transfer operations.
Each GL 18 threaded port enables independent inlet, outlet, vent, sampling, or feed functions, allowing complex fluid or gas networks to operate through a single bottle interface.

An integrated membrane filter vent ensures safe pressure equalization and sterile air exchange during autoclaving or dispensing.
Manufactured from high-quality, chemically resistant materials, the system maintains its strength and integrity even with aggressive reagents or frequent sterilization cycles.

The GL 45 screw thread connects securely to DURAN bottles, preventing leaks and cross-contamination in pressurized or sterile operations.
Because the DURAN 1129818 Connection System is autoclavable up to 121 °C, it can be reused without losing mechanical stability or sealing efficiency.

This five-port cap design is well suited for bioreactors, media feed systems, and multi-line filtration assemblies that require precise and sterile liquid management.
