250 ml DURAN® pressure plus+ clear laboratory bottle, GL45, without screw cap, pack of 10

DURAN® pressure plus+ GL 45 laboratory bottle, clear, without screw cap and pouring ring, 250 ml The DURAN® pressure plus+ GL 45 laboratory bottles offer a safer option for laboratory applications involving vacuum or pressure. Standard laboratory glass bottles are not designed to safely withstand pressure differences. Due to a modified geometry, the pressure plus+ bottles have guaranteed pressure resistance and thus provide optimum safety for both the user and the contents. The special geometry still complies with ISO 4796-1:2016 to ensure equipment compatibility. The pressure plus+ bottles are certified according to DIN EN 1595. The bottles are formed from high-purity, clear USP/EP Type I borosilicate glass 3.3, known for its excellent thermal behaviour and high resistance to chemical influences. The bottles feature an easy-to-read graduated volume scale and a permanently blue enamel labelling field. The permanently printed batch identification (“Retrace Code”) on each bottle guarantees complete traceability of production. Special features and benefits: Guaranteed vacuum or pressure resistance from –1 bar to + 1,5 bar due to modified geometry (based on ISO 4796-1) The special geometry still complies with ISO 4796-1:2016 to preserve equipment compatibility Highest safety for the user when working under pressure and vacuum Suitable for full vacuum ps = -100 kPa Tested pressure resistance according to DIN EN 1598 Fused and therefore permanently durable blue print for visual distinction from the standard laboratory bottle Easy-to-read scale with graduation marks for measuring the contents Standardised GL thread and coordinated closure systems for a particularly tight seal and easy, clean pouring Application: vacuum filtration, sampling under pressure, storage of volatile solvents, storage of gas-forming materials
