GE Whatman* PTFE 25 mm GD/X Syringe Filters

The GD/X range is specifically designed for filtration of high particulate loaded samples. Constructed of a pigment-free polypropylene housing with a prefiltration stack of Whatman GMF 150 (graded density) and GF/F glass microfiber media. These filters greatly reduce the need to carry out separate prefiltration step with difficult to filter samples and allow you to filter difficult samples with less hand pressure. GD/X Syringe Filters can process three to seven times more sample volume than standard syringe filters. GD/X filter construction facilitates exceptional loading capacity with fast flow rates. This prevents the build up of backpressure typically caused by the blocking of an unprotected membrane.
