DURAN 1129815 Connection System Screw Cap GL 45

DURAN 1129815 Connection System Screw Cap GL 45

The DURAN 1129815 Connection System Screw Cap GL 45 offers a safe, versatile solution for liquid or gas transfer between DURAN® bottles and laboratory equipment.
It integrates two GL 18 ports, allowing independent inlet and outlet connections for filling, sampling, venting, or recirculating fluids.
The built-in membrane filter vent equalizes pressure while maintaining sterility during autoclaving or dispensing operations.

Manufactured from chemically resistant, autoclavable materials, the system delivers long-term durability even with aggressive media or frequent sterilization cycles.
The precision GL 45 thread ensures a tight, leak-proof connection to DURAN bottles, reducing contamination risks and improving workflow safety.

Because the DURAN 1129815 Connection System is autoclavable up to 121 °C, it supports sterile processes and can be reused without losing mechanical strength or seal integrity.
Compact and reliable, it is suitable for liquid handling, gas exchange, and media distribution in modern laboratories.
