Smartline Autosampler KNAUER Optimas
analytical HPLC autosampler with sample tray cooling
Article number: A50071The Smartline Autosampler Knauer Optimas was developed for optimal automation of routine injections.
With a choice of carousel trays, it provides sample vial flexibility and with the proven PASA™ injection concept, reliable and accurate sample handling is guaranteed. The autosampler also features three distinct injection modes, “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 autosampler is equipped with a sample tray containing 84 positions for 1.5 ml vials and 3 positions for 10 ml vials by default. Precolumn derivatization is supported. For all injection modes, sample injection with pressure-assisted sample aspiration (PASA™) is selectable. This technique reduces the risk of bubbles and provides excellent accuracy. The needle does not move to an extra port for injection, and thus prevents contamination. Complete integration into KNAUER’s ChromGate® (based on the EZChrom Elite™ kernel) and ClarityChrom® chromatography data software make the autosampler easy to control. Alternatively, the autosampler can be used in standalone mode.
With sample tray cooling (4 - 22°C).
