DURAN® Standard Cone, finished

Complies with DIN 12249 Form B
Manufactured from borosilicate glass 3.3
Ground (finer grinding quality, less roughness depth)
The finer surface reduces the risk of jamming the cuts.
Minimized grease requirement
Tight closure due to standard ground joint
Glass articles for further processing

Product Overview

The conical ground joint is the most common joint in glass apparatus engineering. Ground DURAN® cores comply with DIN 12249 Form B in their design and meet higher requirements for surface roughness. This reduces the need for grinding grease and the risk of jamming. Ground joints with ground grease or PTFE sleeves should always be used. KECK™ Conical ground joint clamps are the perfect supplement for securing the conical ground joint.
