Features of 1260 Infinity Standard Autosampler
- Reliable injections from 0.1 µL to 100 µL.
- Easy adaption for injection volumes up to 1500 µL for applications ranging from microbore to semipreparative chromatography.
- Low internal volume of 300 µL for the minimum contribution to a system's total internal volume can be even further reduced using "by-pass" mode.
- Overlapped injections for increased productivity.
- Peltier temperature control from 4 to 40 °C for up to 100 2-mL vials containing thermally labile samples (upgrade from non-thermostatted to thermostatted version possible.
