The Whatman™ GD/X non-sterile, Polyvinylidene Difluoride (PVDF) membrane syringe filters are designed to enable the filtration of viscous, hard-to-filter samples greater than 10 mL. Each unit contains a prefiltration stack of Whatman multigrade glass microfiber (GMF) and Glass fiber (GF/F) filters.
Reduces need for multiple syringe filters by processing three to seven times more sample volume than syringe filters without prefilters
Female luer lock for leak-free connections
High-efficiency Whatman GMF 150 and GF/F pre-filter media
Eliminates or greatly reduces the need to carry out separate prefiltration step for difficult-to-filter samples
High viscosity filter enables filtration of “difficult-to-filter” samples
The prefilter contains a high-efficiency borosilicate glass filtration stack that will retain fine particles down to 0.7 μm, allowing difficult sample filtration with less hand force. It reduces the need for multiple syringe filters by processing three to seven times more sample volume than syringe filters without prefilters. The filters can be autoclaved.
Polyvinylidene Difluoride (PVDF) membranes
Polyvinylidene Difluoride membrane is a suitable choice for most HPLC sample preparation applications. The membrane is hydrophilic with low water breakthrough values. It offers good chemical resistance to all common HPLC solvents, has low protein binding and negligible extractables.
