Whatman™ GD/XP™ Syringe Filters
The Whatman™ GD/XP® disposables syringe filter is ideal for use with samples that require inorganic ion analysis as levels of ion extractables are minimized. It is also an alternative choice for users requiring a filter that exhibits extremely low protein binding characteristics. GD/XP® syringe filters contain a two layer prefilter stack comprised of 20µm and 5µm polypropylene filters. The last stage of filtration is a choice of membrane which is positioned below the prefilter stack. Applications include HPLC sample preparation and Trace Metal Analysis.
