DURAN

DURAN is a German brand of laboratory glassware and bottles, manufactured by DWK Life Sciences, with a history dating back to the late 19th century. The brand is known for its borosilicate glass 3.3, which offers high thermal resistance and chemical durability, making it suitable for a wide range of laboratory and industrial applications. DURAN products include round and rectangular glass bottles, media bottles, and safety-coated variants, available in sizes from 50 mL to 5 L and larger. Key specifications include screw closure sizes ranging from 32 mm to 80 mm, with closures made from HDPE or polypropylene, and options for unlined caps or liners. Bottles are offered in colorless or amber glass, with amber providing UV protection for light-sensitive contents. Many DURAN bottles are graduated for volume measurement and are pre-cleaned to varying standards, including volatile organic compound (VOC) removal. Safety-coated bottles feature a plastic outer layer that contains glass fragments in case of breakage, reducing spill risk. 3G Electric supplies DURAN laboratory bottles and glassware to industrial buyers globally, including plant engineers, maintenance managers, and procurement specialists in sectors such as chemical processing, pharmaceuticals, food and beverage, and environmental testing. The product range supports applications requiring precise liquid handling, storage, and transport under controlled conditions. DURAN bottles are designed to meet ISO 4796 and other international standards for laboratory glassware, ensuring consistent quality and performance. 3G Electric provides logistics support for sourcing these items, with availability in various pack quantities (e.g., 6 or 10 bottles per case) to suit bulk procurement needs.

Frequently asked questions

Common questions about DURAN from 3G Electric.

What types of glass are DURAN bottles made from?

DURAN bottles are manufactured from borosilicate glass 3.3, which is a low-expansion glass with high resistance to thermal shock and chemical attack. This material is suitable for autoclaving and repeated heating and cooling cycles, making it ideal for laboratory and industrial use.

What is the purpose of the safety coating on DURAN bottles?

The safety coating on DURAN bottles is a plastic outer layer that encapsulates the glass. In the event of breakage, the coating contains glass fragments and prevents liquid spillage, reducing the risk of injury or contamination. This is particularly useful in environments where hazardous chemicals are handled.

Are DURAN bottles available in amber glass?

Yes, DURAN offers bottles in amber glass, which provides protection against UV and visible light. This is essential for storing light-sensitive substances such as certain chemicals, pharmaceuticals, or biological samples that may degrade when exposed to light.

What closure options are available for DURAN bottles?

DURAN bottles come with screw closures made from HDPE or polypropylene, with options for unlined caps or caps with liners. The closure sizes range from 32 mm to 80 mm, depending on the bottle size. These closures provide a secure seal for liquid storage and are compatible with standard laboratory equipment.

Can DURAN bottles be used for autoclaving?

Yes, DURAN borosilicate glass bottles are autoclavable, provided the closures are removed or loosened to allow pressure equalization. The glass can withstand repeated sterilization cycles at temperatures up to 140°C, making them suitable for aseptic processing and media preparation.

What pre-cleaning standards are available for DURAN bottles?

DURAN bottles are available in various pre-cleaning levels, including 'None' for general use and 'Volatile Organic Compounds' (VOC) cleaned for applications requiring low organic residue. The VOC-cleaned option ensures that bottles are free from organic contaminants, which is critical for analytical or sensitive chemical work.
