For High Sample Throughput The Agilent 1200 Series dual loop autosampler is designed for flexible sample handling for both analytical (10 mL/min flow rate) to preparative scale purification (100 mL/min flow rate). It can be upgraded from non-thermostatted to thermostatted version by adding the Agilent 1200 Series thermostat.
Features:
- Flexible injection volumes with 'fixed-dual loop' concept
- Injection of volumes > 5 mL possible. Multi-draw function that allows larger sample volumes.
- Lowest carry over by external and internal needle wash mechanism
- Injection from variety of sample containers (vials and wellplates)
- Optional Peltier temperature control from 4 to 40 °C for protection of thermally-labile samples
