The 1260 Infinity Autosampler is part of the 1260 Infinity LC system that is compatible with operating pressures up to 1200 bar. It features the next-generation flow-through design for high precision injection of both large and small volumes without the need to change sample loops. Only the injected volume is required from the sample and no valuable sample is wasted for flushing. Inert materials in the metering device seal and needle seat as well as reduced hydraulic volumes achieve extremely low carryover. A new module, the 1260 Infinity Flexible Cube, combines seamlessly with the autosampler for infinite injection flexibility. The Flexible Cube facilitates fixed-loop injection mode for ultra-fast cycle times as well as automatic backflushing of the autosampler’s needle seat for lowest carryover yet.
Features:
- Next generation flow-through design with ultra low system volume for operation up to 1200 bar
- Highest injection precision for both large and small volumes without changing loops
- No waste of valuable sample for flushing
- Short injection cycles for higher productivity through overlapped injections
- Best carryover performance through inert seal and needle seat material as well as backflush of needle seat (requires 1290 Infinity Flexible Cube)
- New cartridge loop for ultimate ease-of-use
- Flexible and convenient sample handling with different types of sample containers such as well-plates and vials – process up to 768 samples unattended with 384-well plates
- Peltier temperature control from 4 to 40 °C for thermally labile samples (requires 1290 Infinity Thermostat)
