Polytetrafluorethylene (PTFE) membranes are naturally and permanently hydrophobic. They are ideal for filtering gases, including humidified air. The extreme chemical resistance of PTFE membranes makes them very useful for filtering solvents or other aggressive chemicals for which other membranes are unsuitable. Because of their hydrophobicity, PTFE membranes must be prewetted with a solvent, such as ethanol, before aqueous solutions can be filtered.
EZFlow® Hydrophobic PTFE Syringe Filters utilized in the clarification and particulate removal from samples. These are offered in 0.2µm or 0.45µm pore sizes and is reinforced with polypropylene (PP) housing. The filter is best made with its Hydrophobic PTFE membrane and ideally used before analytical such as HPLC, IC, and GC. They are available in 13mm, 25mm, and 33mm sample prep syringe filters that are designed for aqueous and organic solution samples. The sample prep syringe filters are used for clarification and particle removal from samples before instrumental analysis such as HPLC, IC, and GC. The filter membranes are reinforced with polypropylene housing with a female Luer-lok inlet and a male Luer slip outlet.
