DURAN pressure plus+ laboratory bottle 1000 ml GL45, without screw cap, pack of 10

DURAN® pressure plus+ GL 45 laboratory bottle, clear, without screw cap and pouring ring, 1000 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 continues to comply with ISO 4796-1:2016 to ensure equipment compatibility. The pressure plus+ bottles are certified according to DIN EN 1595. The bottles are made of high-purity, clear USP/EP Type I borosilicate glass 3.3, known for its excellent thermal performance and high resistance to chemical influences. The bottles feature an easily readable graduated volume scale and a permanently blue enamel marking 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 1600 Fired-in and therefore permanently durable blue print for visual distinction from the standard laboratory bottle Easily readable scale with graduations for measuring the contents Standardized GL thread and matched 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
