High-particulate, challenging sample filtration: Whatman GD/X filters
Filter even the most difficult samples and use less hand pressure with GD/X syringe filters.
- Exceptional loading capacity and fast flow rates – prevents back pressure and clogging of membrane
- Graduated microfiber prefilter from 1 μm to 0.7 μm
- Higher flow rates (3×) compared to unprotected membranes
- Uses glass microfiber-based prefilters
For metals testing and other applications where glass-based compounds could interfere with analysis, we offer a related syringe filter (GD/XP), which uses polypropylene prefilters.
