The DURAN® pressure plus+ GL 45 protect+ coated 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, clear, USP/EP Type I borosilicate glass 3.3, renowned for its excellent thermal performance, and high resistance to chemical attack. The glass is coated with a clear polyamide PA12 plastic coating that offers protection for the user and contents in the event of breakage due to impact. 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.
