DURAN® Standard Cone, diamond-ground
- Manufactured from borosilicate glass 3.3
- Diamond cut (coarser cut quality, more roughness depth)
- Cost-effective alternative to DURAN® cores (not according to DIN)
- Tight closure due to standard ground joint
- Glass articles for further processing
Product Overview
The conical ground joint of sleeve and core is a rigid, self-supporting joint. DURAN® DG cores are not ground according to DIN 12249 and represent the cost-effective alternative to DURAN® cores. 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.
