Duran 1000 ml Clear Glass Media Storage Bottle (GL45 Threads, No Cap)

The Duran 218015455 (DWK Life Sciences) is a premium 1000 ml laboratory media bottle engineered for the highest levels of safety and durability. Manufactured from genuine Schott borosilicate 3.3 glass, this bottle provides exceptional resistance to thermal shock and chemical corrosion, making it suitable for autoclaving, sterilization, and the long-term storage of aggressive reagents. The bottle features the industry-standard GL45 screw thread, ensuring compatibility with a wide array of caps, pouring rings, and automated liquid handling connection systems. With its permanent, high-visibility white enamel graduations and large marking spot, this bottle is a fundamental component in pharmaceutical, clinical, and academic research laboratories worldwide.

Technical Performance and Design

• Borosilicate 3.3 Glass: Complies with international standards (ISO 4796-1) for USP Type I glass, offering nearly inert chemical resistance and a very low coefficient of thermal expansion.

• Thermal Stability: Capable of withstanding temperatures up to 500°C (for short-term exposure) and repeated autoclaving cycles at 121°C without compromising structural integrity or clarity.

• Standardized GL45 Neck: The wide-mouth design facilitates easy filling and cleaning while maintaining compatibility with standard laboratory caps and bottle-top dispensers.

• Trace Code Validation: Features a permanent "Retrace Code" printed on each bottle, allowing for full batch traceability and the download of a Certificate of Conformity via the manufacturer’s database.
