Syringe filters are available with the following membranes: Nylon, MCE, Polyethersulfone, Polypropylene, PTFE, PVDF and Regenerated Cellulose. Porosities range from 0.1 µm – 10 µm, available filter diameters range from 4 mm (up to 2 ml sample volume) up to 30 mm (up to approx. 200 ml sample volume). Adapted with luer-lock in order to prevent filter blow-off. The membrane & porosity is imprinted on filter housing for certain identification.
Depending on your sample volume, the table below shows the recommendations.
| Sample Volume | Sample Loss | Filter Diameter |
|---|---|---|
| up to 2 ml | < 7.5 uL | 4 mm |
| up to 10 ml | < 25 uL | 13 mm |
| up to 100 ml | < 50 uL | 25 mm |
| up to 200 ml | < 137 uL | 33 mm |
The guideline below supports the initial choices to be made regarding pore size and membrane type.
