1260 Infinity Dual Loop Autosampler

Ideal for high throughput analysis, the 1260 Infinity Dual Loop Autosampler delivers flexible sample handling for both analytical (flow rates up to 10 ml/min) to preparative scale purifications (up to 100 ml/min). It features an external and internal needle wash system for lowest carryover contamination. The autosampler may be upgraded to a thermosatted version by adding the 1290 Infinity Thermostated

  • Flexible injection volumes with the 'fixed-dual loop' concept.
  • High throughput using the dual loop design.
  • Capacity for large injection volumes - a multi-draw function enables operators to inject sample with volumes over 5 ml.
  • Lowest carryover due to external and internal needle wash mechanisms.
  • Variable injection modes accommodating both vials and well plates.
  • Optional Peltier temperature control from 4 to 40 °C for protection of thermally labile samples
