Applications:
  • HPLC samples containing low solid content - filtration will improve column life
  • CE (Capillary Electrophoresis) samples - filtration will eliminate spurious peaks
  • Sterile filtration of low volume samples
  • UV/Vis samples - filter directly into cuvette using tube tip
  • Refractometry - filter samples to prevent damage to instrument optics and improve accuracy of results
  • Minimize nonspecific binding to membrane (due to small membrane size)
