Hexagon stoppers for NS connections.

Manufactured from borosilicate glass 3.3 which is resistant to heat and almost all chemicals. They meet the highest quality standards according to DIN 12252. Lower closed end of stopper features a "drip-tip" to ensure adhered liquid is returned to the flask. Hexagonal flat head prevents the stopper from rolling and allows stopper to be stood on end preventing contamination of the ground surface.

The caps are available as a closed-top cap with a high temperature PTFE coated cap liner, or as an open-top cap for use with septum or stopper. Metal closures offer a wide range of temperature tolerances and have a high mechanical strength.
