DWK Life Sciences DURAN™ Laboratory Bottle, pressure plus+, Clear, with DIN 168-1 Thread, GL 45, USP /EP (3.2.1) Light Transmission

The DURAN™ pressure plus+ GL 45 bottles offer a safer option for laboratory applications involving a vacuum or pressure. Standard glass laboratory bottles are not designed to safely withstand pressure differentials. As a result of a modified geometry, the pressure plus+ bottles have a guaranteed pressure-resistance, and consequently offer optimal safety for both the user and contents. The special geometry still conforms to ISO 4796-1:2016 to maintain instrument compatibility. The pressure plus+ bottles are certified in accordance with DIN EN 1595. The bottles are moulded from high-purity, ambered, USP/EP Type I borosilicate glass 3.3, renowned for its excellent thermal performance, and high resistance to chemical attack. The ambered glass meets ultraviolet light protection limits as specified in the current revisions of the USP and EP 3.2.1. The bottles feature an easy-to-read graduated volume scale printed in a distinctive blue enamel. Permanent Retrace Code on each bottle for manufacturing lot traceability..

• Guaranteed vacuum and pressure resistant from –1 bar to + 1.5 bar due to modified geometry (based on ISO 4796-1)
• UV protection up to approx. 500 nm due to external colouration
• The only external application of the colour ensures that internal surfaces have standard DURAN™ glass properties
• Highly resistance, long service-life coating
• The special geometry still conforms to ISO 4796-1:2016 to maintain instrument compatibility
• Optimum safety for working under pressure or vacuum
• Suitable for full vacuum ps = -100 kPa
• Pressure resistance conforms to DIN EN 1595
• Fired-on, highly durable blue ceramic for visual differentiation from the standard laboratory bottle
