The optimized conical design allows the safest and most efficient delivery of mobile phase to HPLC analyzers.– The optimized conical design allows the safest and most efficient delivery of mobile phase to HPLC analyzers – Manufactured from the material of choice for solvent bottles: borosilicate 3.3 glass. This material has an exceptional chemical durability offering a very low inorganic ion extractables profile, and the total absence of any organic extractables. – DURAN® is a borosilicate glass type 3.3 as specified by the international standard ISO 3585, and is classified as a “Type I, Class A low-expansion borosilicate glass” as defined by ASTM-E438-1992 – DURAN® glass is classified by the USP / EP / JP pharmacopoeias as a “Type I neutral glass” – Retrace Code, and certificate for manufacturing lot traceability – On the two larger sizes, the central cavity can accommodate magnetic stir bars for improved mixing – Side vent / drain hole in the base for ultrasonic bath degassing, or water drainage after cleaning – GL 45 thread fits standard HPLC connection caps – Durable white enamel volume graduations The optimized conical design allows the safest and most efficient delivery of mobile phase to HPLC analyzers.– The optimized conical design allows the safest and most efficient delivery of mobile phase to HPLC analyzers – Manufactured from the material of choice for solvent bottles: borosilicate 3.3 glass.
