Plastic housing: The outer casing is typically made of polypropylene (PP), which is resistant to most chemicals and can withstand high pressures.
Filter membrane: The core of the filter, the membrane, comes in various materials depending on the sample’s chemical properties.
Connectors: Syringe filters typically feature Luer lock or Luer slip fittings for a secure connection to a syringe.
Diameter and sample volume: Filters are available in multiple diameters, such as 4 mm, 13 mm, 25 mm, and 33 mm, to accommodate different sample volumes.
Pore size: The pore size, commonly 0.22 µm for sterilization or 0.45 µm for general particle removal, determines the size of the particles that can be filtered out.
Sterility: Syringe filters come in both sterile, individually wrapped versions for medical and biological applications and non-sterile versions for general lab use
