DURAN®, borosilicate glass 3.3, clear, with spout.

• Higher mechanical stability compared with standard glass beakers due to reinforced sturdy rim
• Even distribution of wall thickness
• Very good chemical resistance, good thermal resistance

With easily legible graduation and labelling area. It is recommended to heat the Super Duty glass beakers slowly and evenly to prevent thermal stresses in the glass. For work at very high temperatures or with fast changes in temperature, the standard DURAN® beakers should be used, as these offer excellent resistance to temperature changes. However, mechanical stability is limited with these products in comparison with the Super Duty beakers.

With printed retrace code (batch identification).
