DURAN®, borosilicate glass 3.3, clear.

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

With easy to read graduations and a white labelling area. Higher mechanical stability compared to standard Erlenmeyer flasks due to increased wall thickness, plus reinforced sturdy rim and base. Even distribution of wall thickness. It is recommended to heat Super Duty Erlenmeyer flasks slowly and evenly, to prevent thermal stresses in the glass.

With printed Retrace Code (batch identification).
