Erlenmeyer flasks with thread, DURAN®

DURAN®, borosilicate glass 3.3, clear, without or with red PBT screw cap.

• Very good chemical resistance
• High temperature resistance
• Minimal thermal expansion, giving relatively high resistance to temperature changes

Volume graduations and labelling area. A PTFE-coated seal incorporated in the cap guarantees that the flasks are absolutely leakproof.
