Selecting Right Membrane Syringe Filter, you have to remember below steps:

• Choose the size of filter based on the volume of sample that must be filtered.

•  Choose the porosity of the filter based on the size of potential particulates that may be present in your sample. Remember, the finer the porosity the more pressure it will take to pass sample through the filter. If you have a great deal of particulate matter, you may want to use a glass fiber filter, place a glass fiber pre-filter in front of your membrane filter to prevent rapid plugging or use a 2-in-1 filter that has a built-in pre-filter in a single housing.

•  Choose the membrane type based on the solvent that you want to filter.
