Laboratory bottle/DURAN, 500 ml (thread GL 45), 10 pc/PAK

DURAN® pressure plus GL 45 Laboratory Bottle, clear, without screw cap and pouring ring, 500 mL The DURAN® pressure plus GL 45 Laboratory 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 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. Features and Benefits: Guaranteed vacuum and pressure resistant from –1 bar to 1.5 bar due to modified geometry (based on ISO 4796-1) The special geometry still conforms to ISO 4796-1:2016 to maintain instrument compatibility Optimum safety for working under pressure or vacuum Suitable for use under a perfect vacuum (100%) 0 torr, 0 psia or 0 Pa absolute Pressure resistance conforms to DIN EN 1595 Fired-on, highly durable blue ceramic print for visual differentiation from the standard laboratory bottle Easy-to-read scale with graduation marks to estimate the content Standardised GL-thread and matching cap system for particularly tight sealing and simple, clean pouring out Application: Vacuum filtration, Collection of samples under pressure, Storage of volatile solvents, Storage of gas generating materials
