GH Polypro (GHP) Membrane Disc Filters Hydrophilic polypropylene membrane with maximum chemical compatibility when filtering both aqueous solutions and aggressive solvents. High recovery of critical proteinaceous samples due to low protein binding. HPLC certified. 47mm diameter. Pore size: 0.2um.
Hydrophilic membranes, which have an affinity for water, are preferable when filtering aqueous samples. Use MS filters with GHP, PES, Nylon, or PVDF membranes. Hydrophobic membranes repel water and are inert to aggressive organic solvents, making them ideal for gases and organic solvents. Choose MS filters with PTFE membrane.

Aug 07, 2018 · DO USE: for filtering solvents and other aggressive chemicals, such as acetone and DMSO. MAYBE USE: when you need to filter aqueous solutions and sodium hydroxide. You’ll need to pre-wet with a water-miscible solvent, such as methanol, to overcome the hydrophobicity of the membrane. Polyvinylidene Fluoride (PVDF) Membrane

The membrane is laminated onto a nonwoven polypropylene support web for improved strength and handling and can be used at temperatures up to 120ºC. Chemically stable and inert PTFE is the membrane of choice for use with aggressive solvents, liquids, and gases that can attack other membranes. It is resistant to most acids, alkalis, and solvents.
The GHP membrane is compatible with acids and bases, as well as aggressive organic solvents and halogenated solvents. These unique characteristics of the GHP membrane allow the Acrodisc syringe filter to serve as a universal membrane for use across a wide range of sample prep applications.
