A widely used standard grade filter paper for routine applications with medium retention and flow rate.

- Single thickness thimbles have a wall thickness of approximately 1 mm (10.0 μm nominal particle retention)

- Pore Size: 1.5μm
- High retention, Fast flow

Syringe Filter, PTFE

Slightly more retentive than Grade 1 with a corresponding increase in filtration time (i.e., slightly slower filtration speed).

Syringe Filter, PVDF

A standard grade filter used in qualitative analytical techniques to determine and identify materials. For use in büchner funnels.

- 1.0μm Pore size
- 3x thicker than GF/A

Syringe Filter, Nylon

Fast flow & retention of coarse precipitates
