Life can be tough for laboratory glassware such as beakers, flasks and cylinders. Rough handling and laboratory processes like automated washing can cause damage and breakages. The DURAN® SUPER DUTY products were specially developed to better cope with laboratory life. The DURAN® SUPER DUTY products are characterized by a higher mechanical strength achieved by reinforcing the rim. As a result of this modification, the impact strength is improved, and the risk of accidental breakage is significantly reduced. The DURAN® SUPER DUTY products increase the safety in the laboratory and help to minimize the risk of injury. The longer life expectancy of the SUPER DUTY products means that they are more economical to use over the long term. The DURAN® SUPER DUTY products are characterized by a higher mechanical strength achieved by reinforcing the rim. As a result of this modification, the impact strength is improved, and the risk of accidental breakage is significantly reduced.

• Higher impact strength, mechanical strength and stability achieved by reinforced rim
• Due to reduced risk of accidental breakage the risk of injuries is minimized and the safety of the user is increased
• Economical due to longer life span and outstanding corrosion protection
• White easy-to-read scale with graduation marks to estimate the content
• Fired-on, highly durable white ceramic
