DURAN 1129816 Connection System Screw Cap GL 45

DURAN 1129816 Connection System Screw Cap GL 45

The DURAN 1129816 Connection System Screw Cap GL 45 is designed for multi-line fluid and gas handling in laboratories that require sterile, closed transfer systems.
Equipped with three GL 18 threaded ports, it enables simultaneous inlet, outlet, and vent connections, supporting complex operations such as sampling, media exchange, and recirculation.

An integrated membrane filter vent provides pressure equalization and sterile air exchange during autoclaving or dispensing.
Made from chemically resistant, autoclavable materials, this connection system ensures long service life even under demanding conditions.

The GL 45 thread fits securely to DURAN bottles, creating a tight, reliable seal that prevents leaks and contamination.
Because the DURAN 1129816 Connection System is autoclavable up to 121 °C, it can be sterilized and reused repeatedly without degrading performance.

This multi-port design enhances workflow efficiency in biotechnology, cell-culture, pharmaceutical, and analytical laboratories that rely on precise, sterile liquid handling.
