GPC Autosampler
GPC Autosampler
GPC AutosamplerThe Viscotek GPC Autosampler is specifically designed for GPC using a fixed volume sample loop for excellent reproducibility. The easy programming and variable wash programs combined with a large vial capacity give the autosampler maximum flexibility. Options are available for variable volume injection programming, temperature control and large vials for semi-preparative work.







Key Features include:
  • Excellent reproducibility - the autosample overfills a fixed volume loop
  • Easy programming through the interactive screen
  • Chemically resistant to a wide range of GPC eluents
  • Flexible wash programming to minimize carry-over
  • Optional variable volume injection loop programming
  • Two removable vial tracks, each with 60 positions
  • Heating/Cooling option available
