Pall Gelman’s universal solvent filter is the GHP Acrodisc, which includes an all-purpose membrane, GH Polypro (GHP), that is effective for harsh aqueous samples and for aggressive organic solvent-based solutions. The GHP Acrodisc is the most versatile filter available in terms of broad chemical compatibility with bases, acids and organic

Hydrophobic membranes repel water and are inert to aggressive organic solvents, making them ideal for gases and organic solvents. Choose Pall filters with PTFE membrane. Aqueous and Organic-Solvent Solutions. Different polymeric membranes have different chemical compatibilities. Based on the application and chemical compatibility, there may be one or several membranes and Acrodisc syringe filter possibilities.

How to Choose MS Syringe Filter - Membrane Solutions. 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.

The GHP membrane used in Pall Laboratory Acrodisc® syringe filters, centrifugal devices and Acroprep™ filter plates will be discontinued due to the rationalization of a key material from our supplier. However we are excited to announce the launch of the NEW wwPTFE universal membrane as a direct replacement for GHP filtration products.
