The Whatman GD/X® range of syringe filters has been specifically designed for high particulate loaded samples. A pre filtration stack eliminates sample contamination enables high loading capacity, fast flow rates and eliminates back pressure allowing difficult samples to be filtered with less hand pressure. GD/X® syringe filters can process three to seven times more sample volume than unprotected membranes.

Especially useful for particulate-laden samples found in: Dissolution testing; Content uniformity; Concentration analysis, food and environmental samples and composite assay. Key features and benefits include:

• 13mm filters for samples up to 10mL
• 25mm filters for samples greater than
• Sterile options
• Pigment-free polypropylene housing
• Novel prefiltration stack of GMF 150 (graded density) and GF/F glass microfibre media
