CHROMAFIL® syringe filters
Features
Syringe filters are used for filtration of suspended matter from liquid samples or gases. With CHROMAFIL®, rapid purification and removal of particles is very simple: just place the filter on the syringe, and you are ready for filtration. Special manipulations are not required. Contamination of sensitive instrumentation by solid impurities can be avoided, thus increasing lifetime of chromatographic columns and equipment.

Pressure stability of housing > 12 bar (for 13, 15, 25 mm filters)
 
Recommended filter size depending on sample volume

  Sample volume   recommended filter diameter
  ≤ 1 mL   3 mm
  1–5 mL   13 / 15 mm
  5–100 mL   25 mm
