1290 Infinity Autosampler 

The 1290 Infinity Autosampler features 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 1290 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 carry over.
