Autosampler AS 6.1L

Product No:

AAA31AA

preparative HPLC autosampler with biocompatible flow path and cooling option


biocompatible, preparative version with sample cooling/heating

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 2 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. “partial loop filling” (variable volumes, e.g. for dilution series) is supported. The headspace pressure function prevents bubbles from forming in the vial during sample uptake. Precolumn derivatization is supported. Preparative version for sample volumes up to 10 ml with biocompatible flow path.
