Duran® Super Duty Beaker features a increased mechanical sturdiness due to increased uniform wall thickness and reinforced, sturdy rim. Made of Type 1/ neutral glass, autoclavable. Available sizes: 150 mL, 250 mL, 400 mL, 600 mL, 1,000 mL, 2,000 mL, and 5,000 mL.
To avoid thermal stressing of the glass, uniform and slow heating of super duty bottles is recommended.
