A helping hand for nature

Photobioreactors require glass apparatus with specific properties to facilitate the cultivation of algae in the fields of nutrition and cosmetics. DURAN® tubes, manifolds, u-bends and j-bends prove highly useful thanks to their strong, stable light transmission and thermal resistance.

DURAN® borosilicate glass tubing used in industrial heat exchangers and condensers

Heat exchangers and condensers

The transfer of heat between two or more gases is key to a range of industrial processes, and DURAN® glass is highly suitable due to its outstanding thermal shock and corrosion resistance. A key fixture in power stations and petrochemical plants, heat exchangers and condensers can also be found in air-conditioning and refrigeration units, as well as sewage treatment plants.

DURAN® borosilicate glass tubing used in industrial explosion-proof lighting

Explosion-proof lighting

The exceptional heat resistance of DURAN® makes it the ideal choice for lighting where there’s a danger of explosion or similar dangerous reaction due to high temperatures. Its strong transparency and electrical insulation properties add to its suitability.

The right chemistry

The geometrical precision and high chemical resistance of DURAN® glass tubing make it a popular choice for the equipment used in industrial chemical plants. Its high resistance to corrosion caused by water, acids, saline solutions, alkaline solutions and organic substances give it the stability required for these harsh chemical environments.

DURAN® borosilicate glass tubing with high heat resistance used in sight glasses

Sight glasses for extreme conditions

The operation of tanks or boilers can depend on sight glasses that enable observation of the liquid levels within. However, strong pressures and high temperatures require a glass with exceptional heat resistance and mechanical resilience, as well as stable properties to ensure reliable operation. DURAN® provides the solution to all these challenges.

DURAN® borosilicate glass tubing used in exterior and interior architecture design

Attractive and functional architecture

The mechanically rugged nature of DURAN® means it can be used in architecture as an attractive and stylish feature in both exterior and interior designs. When combined with creative lighting, it can result in a truly stunning effect that doesn’t compromise on safety or functionality.

DURAN® borosilicate glass tubing used in sprinkler fuses that trigger sprinkler action

Sprinkler systems for safety

DURAN® is a highly suitable choice in the design of sprinkler fuses. Since its round geometry is tightly controlled, it allows the fuse to consistently and reliably react to changing temperature conditions upon the outbreak of fire, triggering sprinkler action.
