250 ml DURAN® pressure plus+ brown lab bottle, without screw cap, GL45, Ø70mm, H138mm, pack of 10

DURAN® pressure plus+ GL 45 laboratory bottle, brown, 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: Made of amber-coloured borosilicate glass 3.3 Guaranteed vacuum and pressure resistance from -1 bar to + 1.5 bar due to modified geometry (based on ISO 4796-1) Compliant with USP, USP (Spectral Transmission) and EP (3.2.1). Less than 10% spectral transmission between 290 and 450 nm. The external application of the colour only ensures that the inner surfaces retain the standard DURAN® glass properties Highly resistant, durable coating The special geometry still complies 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 according to DIN EN 1595 Permanently durable blue printed image, fired in and therefore permanent, for optical differentiation from the standard laboratory bottle Application: Storage of light-sensitive materials, vacuum filtration, pressurised sampling, storage of volatile solvents, storage of gas-forming materials
