Syringe Filter, GD/XP, PTFE, 25 mm, 0.45 µm, 150 pc/PAK

Housing: polypropylene (non-pigmented), filter area 4.6 qcm, maximum pressure 75 psi, inlet: internal Luer lock, outlet: external Luer, autoclavable at 121°C /15 psi (applies to non-sterile filters only), pre-filter polypropylene PP 20 µm: 5 µm

Whatman GD/XP ready-to-use syringe filters are ideal for samples being analysed for inorganic ions, as the amount of extractable ions is kept to a minimum. They are also an alternative for users who require a filter with extremely low protein binding properties. GD/XP Syringe Filters have a double pre-filter layer of 20 µm and 5 µm polypropylene filters. A choice of membranes can be positioned under the pre-filter layer for the final stages of filtration.

The GD/X syringe filters allow you to filter even the most difficult samples with less manual pressure.

• Exceptional loading capacity and fast flow rates prevent back pressure and membrane clogging
• Graded microfibre pre-filters from 1 μm to 0.7 μm
• Higher flow rates (3x) compared to unprotected membranes
• Uses glass microfibre based pre-filters
• For metal analysis and other applications where glass-based compounds may interfere with the analysis, we offer a suitable syringe filter (GD/XP) that uses polypropylene pre-filters.
