Cowie Technology™ PTFE Joint Adapters are grease-free and create high vacuum seals for standard taper ground glass joints.

Creates high vacuum with sealing rings, negating the need for grease. Cowie Technology™ PTFE Joint Adapter are autoclavable and reusable.

The rubber sleeve is required to achieve gas tightness during vacuum filtration.

Filled with a desiccant, the drying tube protects a reaction mixture in a flask from moisture.

Designed for a rigid, self-supporting connection with lower requirements.

Intended for use with female spherical cup joints FS:

For a rigid, self-supporting connection.

For safe connection of hoses.

For ground joints in the high vacuum range.

For use with male ball joints MS:

For attaching to a wide variety of apparatus.

Smallest gap dimensions in use with agitator shafts allow completely smooth running and working under vacuum.

For a rigid, self-supporting connection.

For ground joints in the high-vacuum range with extension.

For attaching to a wide variety of apparatus.

The threaded tube with thread and standard ground joint allows the bonding of various glass components.

For a rigid, self-supporting connection.

Manufactured with minimum shank length of 100mm

The transition adapter connects two glass components with different standard ground joints.

For grease-free flexible connections.

Core cut with extension.

For use on a wide variety of apparatus with higher mechanical strength requirements.

The KPG stirring shaft is a stirrer that fits exactly on the KPG bearing sleeve and is suitable for stirring viscous media.

For ground joints in the high vacuum range.

Reduction from sleeve to core.

Component of the system for the safe loosening of stuck ground joints.

Use as an alternative to magnetic stirrers with high viscosity or high stirring speeds.
