HPLC reservoir bottle GL 45 with conical base DURAN® DWK

The DURAN® reservoir bottles have been specially designed for the storage and delivery of high-performance liquid chromatography (HPLC) mobile phases and solvents. Reservoirs have a one central cavity for the inlet filter to allow the most efficient delivery of mobile phase to HPLC analyzers. A safer and more convenient alternative to flat bottomed glass media bottles, the conical bottom reservoirs allow a greater recovery of solvent, without having to tilt reservoir and risk a solvent spill. The larger reservoirs allow longer, uninterrupted analyses. These are especially useful during a weekend or lengthy chromatographic analysis when there might be a risk of running out of solvents during unattended operation. 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.
