100PCS PTFE Syringe Filters 13mm 25mm 0.22μm 0.45μm Hydrophilic or Hydrophobic Membrane Filters for Laboratory Sample Preparation (Hydrophilic 13mm 0.22μm)

These PTFE Syringe Filters are designed for routine laboratory sample preparation, liquid clarification, particle removal and small-volume filtration. Available configurations include 13mm and 25mm filter diameters with either 0.22μm or 0.45μm pore sizes. Hydrophilic and hydrophobic membrane options are provided for different liquid-handling requirements. The compact disc-shaped housing connects conveniently to compatible laboratory syringes. Welded housing construction helps keep the membrane securely positioned during routine manual filtration. The transparent housing allows convenient observation of liquid flow. Select the required diameter, pore size and membrane type according to the sample volume, material properties and laboratory procedure. Each package contains 100 filters in the selected configuration. Confirm material compatibility and operating conditions before use.

• Eight Configuration Options: Choose between 13mm or 25mm diameters, 0.22μm or 0.45μm pore sizes, and hydrophilic or hydrophobic membrane types.
• PTFE Filter Membrane: Designed for routine laboratory filtration, sample clarification and removal of suspended particles from compatible liquids.
• Hydrophilic or Hydrophobic: Hydrophilic options support compatible water-based and mixed solutions, while hydrophobic options are intended for compatible organic liquids, gases and venting applications.
• Convenient Syringe Connection: Compact housing attaches to compatible laboratory syringes for controlled, small-volume manual filtration and sample preparation.
