An effective filtration area can be defined as the total area of the filter media that is exposed to the flow of liquid or air, that is usable for filtration. This is often designated in square centimetres (cm2), square inches (in2 ) or square feet (ft2 ).
GH Polypro (GHP) Membrane Disc Filters All purpose, universal membrane with maximum chemical compatibility for both aqueous solutions and aggressive solvents Specifications Filter Media Hydrophilic polypropylene Pore Size 0.2 and 0.45 µm Typical Thickness 0.2 µm: 101 µm (4.0 mils) 0.45 µm: 114 µm (4.5 mils) Typical Water Flow Rate mL/min
Aug 07, 2018 · Cellulose Acetate (CA) Membrane. Hydrophilic filtration membrane with limited chemical resistance but made from pure cellulose acetate, which is very low protein binding and so excellent for protein recovery. Withstands temperatures up to 180°C, making it well suited for hot gases.
2019/9/11 · These four folding filter cartridges have excellent chemical compatibility, suitable for filtering strong acid, strong alkali and organic solvent, large membrane filtration area, low pressure difference, strong dirt holding capacity and more effective application life.
Pall GHP Polypropylene membrane will be discontinued effective October 31st, 2019. This discontinuation affects devices including Filter Plates, Syringe Filters, Centrifugal Devices and Membrane Filter Discs. Essential for biomolecule purifications and separations filter plates are offered in different filtration media membrane to accommodate any array applications. With individual membranes
Mobile phase filtration is performed prior to placing the solvent into the solvent reservoir. Buffered mobile phase solvents require daily filtration with a 0.2 μm filter to eliminate microbial growth that could increase the baseline. The primary concern when choosing a solvent filter is solvent compatibility with the filter material.
Pall Laboratory. of filter media: hydrophilic nylon membrane for excellent chemical compatibility with esters, bases, and alcohols, without pre-wetting; GHP (hydrophilic polypropylene) membrane for low protein binding; and hydrophilic PVDF (polyvinylidine fluoride) membrane for use in aqueous and non-aggressive,.

The definition of solvent compatibility for Millipore products differs from that used in determining the ratings given in published compatibility tables. Such tables are generally concerned with chemical attack and significant losses in strength and/or dimensional changes. A top designation, for example, might be designated for solvent-polymer
It is important to choose a filtration membrane that has high chemical compatibility with the mobile phase solvents used in the lab. Polytetrafluoroethylene (PTFE), polyvinylidene difluoride (PVDF), and regenerated cellulose (RC) membranes are popular choices, because they are highly compatible with common mobile phase solvents such as purified water, acetonitrile, and methanol.
Syringe Filters Solvent Compatibility Chart 1 Protect any analytical system. 2 Extend LC column lifetime. 3 Achieve more reproducible analyses. 4 Variety of membranes, porosities, and diameters available. 5 Luer lock inlet provides strong, leak-tight syringe connection to withstand filtration pressure.
Membrane integrity for syringe filters was tested by bubble point. This chart is intended only as a guide. Accuracy cannot be guaranteed. Users should verify chemical compatibility with a specific filter under actual use conditions. Because chemical compatibility is affected by many variables (including temperature,
