GUKO DURAN Rubber Gasket Conical 292021709

The DURAN GUKO 292021709 Rubber Gasket Conical is designed to seal filter funnels and flasks in laboratory filtration systems.
Its conical shape ensures a snug fit between glass joints, preventing leaks during vacuum or gravity filtration.

Manufactured from high-grade EPDM rubber, this gasket maintains flexibility even under temperature changes or repeated autoclaving.
The material resists common laboratory solvents, acids, and bases, guaranteeing consistent performance.

The gasket’s dimensions — top Ø 29 mm, bottom Ø 16 mm, and height 23 mm — provide an excellent fit for standard DURAN and GUKO filtering systems.
Durable and reusable, it withstands autoclaving up to 150 °C without deformation, ensuring long service life and reliability.
