Sterile, individually packed syringe filter for laboratory sample preparation. This SKU combines a 25mm housing and 0.22um pore size with PES (polyethersulfone, hydrophilic) membrane, supplied as a pack of 50 filters.

The filter is intended for polishing and clarifying liquids before analysis, protecting chromatography columns, analytical instruments and microbiological tests from particles and particulates.

The sterile housing and individual packaging help reduce contamination risk for sensitive biological samples and routine aseptic filtration workflows.

Membrane material and performance:

- Membrane type: PES (polyethersulfone, hydrophilic).

- Characteristics: High-porosity hydrophilic membrane with very low protein and drug adsorption, fast flow, and good suitability for biological samples, culture media, serum, buffers and aqueous formulations.

- Recommended maximum filtration temperature: 100°C.

Size and pore rating:

- Housing diameter: 25mm.

- Pore size: 0.22um.

- Pack size: 50 pieces.

Typical use: Sample clarification, particle removal, pre-filtration before HPLC/UPLC/GC sample injection, microbiology media preparation, and filtration of small-volume laboratory samples.

Storage: Store clean and dry at room temperature. Keep sealed until use.
