PTFE is a stable material suitable for filtering water, organic solutions, strong acids, and alkaline solutions. Not suitable for trichloroethylene, gasoline, hexane, etc. Ideal for sample clarification filtration, liquid chromatography filtration, and similar applications. This filter is for single-use only, with a typical filtration volume of approximately 10 ml per unit (actual volume may vary depending on the level of impurities in the liquid). The filter membrane is not reusable or disassemblable. A pore size of 0.22μm effectively removes common particulates and contaminants visible to the eye. Designed for use with standard syringes. Diameter: 25mm Pore size: 0.22μm Interface: Standard syringe port, compatible with conventional luer-lock syringes Upper interface outer diameter: approx. 6.5mm; inner diameter: approx. 4.4mm Lower interface (needle end) outer diameter: approx. 4mm; inner diameter: approx. 2.2mm Filtration area: 0.85cm² Dead volume: Less than 30μL Maximum filtration pressure: Less than 100 psi Maximum operating temperature: Less than 60°C Color: As shown in image Material: PTFE Package Contents: 100 x Filter units Note: The package includes only the items listed above. Other accessories are not included. Slight color variations may occur due to lighting conditions and display differences. Measurement tolerances may vary by ±1–3 cm.
