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.
- Selection of Filter Diameter
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|
- Selection of Pore Size and Membrane Type
The guideline below supports the initial choices to be made.
- Solvent Compatibility Table
The table below illustrated the compability of the filter membranes with different solvents.
(Y = compatible, L = limited compatible, X = not compatible)
