Description & Specifications

Specifications

Type Syringe Filter
Diameter (Metric) 4mm
Housing Material Pigment-free Polypropylene
Volume (Metric) Up to 2mL

  • Diameter: 4mm
  • Sample volume up to 2mL
  • Low hold-up volume <10μl ensures maximum sample recovery
  • Tube-tip format (optional)
  • Wide sample compatibility
  • Choice of membrane or glass microfiber filter media
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)
