PP Syringe Filters
Description
Cost-Effective Hydrophobic Filtration for General Laboratory Use
Hawach PP syringe filters are designed for broad laboratory filtration applications, offering excellent chemical resistance, low protein binding, and high dirt-holding capacity.
Constructed from pure polypropylene (PP), these filters are:
- Slightly hydrophobic
- Highly chemically resistant
- Suitable for both aqueous and organic samples
- Ideal for pre-filtration and general clarification
Widely used in HPLC, ion chromatography, and routine lab workflows
Recommended Configuration
PP Syringe Filters (0.22 µm / 0.45 µm)
- Cost-effective for routine filtration
- Low protein adsorption → suitable for biomolecules
- High porosity → strong dirt holding capacity
- Compatible with acids, bases, and many solvents
- Available in sterile and non-sterile formats
Best for pre-filtration, sample cleanup, and general lab use
