Violamo multi-layer syringe filter (hydrophobic PTFE) 0.22μm φ25mm 1 box (100 pieces) PTFE2G-025S022O 1 box (100 pieces)

Two types of pre-filters are built in for more efficient filtration. It has a built-in first layer with an inclined pore size of 10 to 1.0 μm and a second layer made of GF prefilter with a pore size of 0.7 μm, making it less likely to clog. Suitable for hard-to-filter samples such as suspensions and highly viscous liquids. It has a larger processing capacity than types without pre-filter or two-layer structure types. The hydrophobic PTFE membrane has excellent chemical resistance and is compatible with various organic solvents, acids, and alkaline solutions (water-based solutions cannot pass through due to its water-repellent properties). Pore size (μm): 0.22 Filter diameter (mm): φ25 Material: Membrane filter/hydrophobic PTFE, prefilter/glass fiber, housing/PP Maximum operating temperature: 45℃ Effective filtration area: 3.9cm2 Maximum operating pressure: 0.52MPa Residual volume: 150μL or less Liquid to be filtered: Organic solvent-based solution Connection: Inlet/female Luer lock, outlet/male Luer lock *Chemical resistance varies depending on filtration conditions, so we recommend testing before use. *This product is for research and development purposes only.
