Syringe filters are single-use, membrane-based devices used to remove particulate contamination from small volumes of liquid before analysis (such as HPLC, GC, or IC). Choosing the correct membrane material is critical to ensure chemical compatibility and prevent sample loss.
Nylon is a very popular, naturally hydrophilic membrane. It is widely used for general laboratory filtration and sample preparation for analytical chemistry.
Polypropylene is a versatile, hydrophobic membrane (though often available in hydrophilic-treated versions). It is known for its extreme chemical resistance and low background levels.
