Biocompatible analytical FPLC Autosampler


analytical HPLC autosampler with biocompatible flow path

The Autosampler AS 6.1L can inject from up to 768 positions when equipped with microtiter plates (either high or low formats) or from up to 108 standard 1.5 ml sample vials. Sample carryover is significantly minimized thanks to a highly-effective interior and exterior needle wash procedure. This autosampler is also fast and flexible: one complete sample injection cycle takes less than one minute, including needle wash. Three different injection modes are supported; “full loop filling” (highest precision and reproducibility), “partial loop filling” (variable volumes, e.g. for dilution series) and “µl pickup” (loss-free injection of extremely small sample volumes), allowing the user to optimize sample usage. The headspace pressure function prevents bubbles from forming in the vial during sample uptake. Precolumn derivatization is supported.
With biocompatible sample path.
