DURAN® GL 45 laboratory glass bottle, pressure plus, pressure-resistant, brown, without screw cap and pouring ring, 100 ml

DURAN® pressure plus+ GL 45 laboratory bottle, brown, without screw cap and pouring ring, 100 ml The DURAN® pressure plus+ GL 45 laboratory bottles offer a safer option for laboratory applications with vacuum or pressure. Standard laboratory glass bottles are not designed to safely withstand pressure differentials. With a modified geometry, pressure plus+ bottles have guaranteed pressure resistance, providing 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 molded from high-purity, clear USP/EP Type I borosilicate glass 3.3, known for its excellent thermal behavior and high resistance to chemical attack. The bottles feature an easy-to-read graduated volume scale and a durable blue enamel labeling panel. The permanently printed batch identification ("Retrace Code") on each bottle guarantees full traceability of production. Special features and benefits: Made of amber borosilicate glass 3.3 Guaranteed vacuum and pressure resistant from -1 bar to + 1.5 bar due to modified geometry (based on ISO 4796-1) USP , USP (Spectral Transmission) and EP (3.2.1) compliant. Less than 10% spectral transmission between 290 and 450 nm. External application of color only ensures that internal surfaces exhibit standard DURAN® glass properties Highly durable, long-lasting coating Special geometry remains compliant with ISO 4796-1:2016 to ensure instrument compatibility Optimum safety when working under pressure or vacuum Suitable for use under high vacuum Pressure resistance in accordance with DIN EN 1595 Burnt-in and therefore permanently durable blue printed image for visual differentiation from the standard laboratory bottle Application: Storage of light-sensitive materials, vacuum filtration, sampling under pressure, storage of volatile solvents, storage of gas-forming materials
