Components

With conical ground joint. DIN 12257.

Flexible jawsExcellent chemical resistanceHigh mechanical strength

Manufactured from borosilicate glass 3.3 which is resistant to heat and almost all chemicals. With liebig condenser and socket NS14/23 for distillation thermometers.

For use with ground glass joints. Suitable for vacuums up to 0.1mbar. Reusable and long lasting. The sealing ribs grip on the inside wall of the glass socket, sealing without the need for grease and enabling the cone to be freed easily when required.

Melting point 175 °C. Excellent chemical resistance. Rigid. Heat resistant up to 150 °C, sizes colour coded.
