Pall Life Sciences Nylaflo Nylon Membrane Filters are made of Nylaflo Nylon Membranes. These hydrophilic materials require no pre-wetting. They are certified for low levels of extractables and have a low protein affinity.
They have excellent chemical compatibility with esters, bases and alcohols. No pre-wetting is required for aqueous solutions.
The FP Vericel(TM) Polyvinylidene Membranes are HPLC certified for low levels of UV-absorbing extractables. They are hydrophilic membranes for both aqueous and non-aggressive solvent-based mobile phase.
The GH Polypro Polypropylene Membranes have a versatile filter that can handle aqueous and aggressive organic solvent-based solutions. The universal membrane is suitable for proteinaceous samples.
The HT Tuffryn® Polysulfone Membranes have a very low protein binding for recovery of media components. They are made of a durable and easy to handle material.
The Metricel® Mixed Cellulose Ester Membranes are the most accepted filter media for microbiological analysis. They are available in plain or in a grid pattern for quantification. They have a 0.45µ pore size for maximum retention of organisms
