the membrane, not leak around it. Denville Syringe Filters are easy to use. They may be used with any luer-lock syringe and are color-coded for easy recognition. The 30mm syringe filters can filter up to 100mL of sample with a retention volume of less than 100µL. up to 100mL of sample with a retention volume of less than 100µL.
Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see table below for a full selection of mebranes). For aqueous samples, it is preferable to use a hydrophilic membrane (wwPTFE, PVDF, or Nylon) versus a hydrophobic membrane (PTFE).
