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 Thermostat.
