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 analysers. 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 the reservoir and risk a solvent spill, or introduction of air bubbles. 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. Reservoirs are ideal for large-scale production using flow chemistry.

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
Optimised conical design allows the safest and most efficient delivery of mobile phase to HPLC analysers
Ideal for large scale production using flow chemistry, conical bases significantly reduce the amount of unused solution, reagents and solvents.
Analyser compatibility GL 45 thread fits standard HPLC connection caps
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 (5000 and 10000mL), the central cavity can accommodate magnetic stir bars for improved mixing
