Sep 03, 2013 · GHP hydrophilic polypropylene (GH Polypro) is ideal for chemical compatibility, fast flow rates, low protein binding, and low levels of UV-absorbing extractables. Glass fiber prefilters allow for quick and easy filtration for difficult-to-filter aqueous solutions.

Membrane Type (PTFE, GHP, PVDF, Nylon) — Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see chart opposite). For aqueous samples, it is preferable to use a hydrophilic membrane (GHP, PVDF or Nylon) versus a hydrophobic membrane (PTFE).

The GH Polypro hydrophilic polypropylene membrane is ideal for aqueous solutions and offers maximum chemical compatibility for aggressive solvents. 96.5% protein recovery. GH Polypro membrane is a low protein binding membrane. It removes unwanted particulate from samples with high recovery of critical proteins.

Differences between hydrophilic membranes and hydrophobic membranes. A hydrophobic membrane, such as polytetrafluoroethylene (PTFE) will resist any aqueous sample, creating back pressure. Although it is sometimes possible to overcome this back pressure with additional force, there is a risk of membrane rupture and incomplete filtration.

Hydrophilic membrane filters are typically used with water and aqueous solutions. They can also be used with compatible non-aqueous fluids. Hydrophilic membrane filters are typically not used for air, gas or vent filtration since the filters would block flow if inadvertently wetted, by condensation for example.
