PTFE Syringe filters for convenient filtration of small sample sizes through membranes. Cellulose acetate membranes are hydrophilic membranes that offer excellent flow rates. They are low protein-binding and provide superior chemical resistance to alcohols and oils. They are best used at a pH of 4-8 and an operating temperature below 180 degrees Celsius.
