Clogged Tip Detection |
Insufficient Liquid Detection |
|
|
If the tip clogs during aspiration the pressure will spike down.As the plunger moves, sample is not being aspirated to help equalizethe pressure. |
If there is insufficient liquid in the tube, the pressure curvewill start down as normal but then will return to a pressure muchhigher than the expected level represented by Δp in the graph.The higher pressure is a result of having less liquid in the tipdue to an incomplete aspiration. |
Aspiration of Foam |
Droplet Prevention |
|
|
If ZEUS pipettes foam instead of liquid, the pressure sensordetects spikes during the aspiration. Based on the severity of thespikes, a threshold can be set for a failed aspiration. |
Volatile liquids like acetone and methanol can be extremely difficultto pipette using air displacement. These liquids tend to vaporizein the tip which raises the air pressure resulting in liquid drippingfrom the tip. ZEUS is equipped with Anti-Droplet Control (ADC).When enabled, the pressure is monitored in the tip. As the pressurerises, the piston is retracted to equalize the pressure and preventdripping. The illustrations show the pressure curve when ADC ison and off. |

The ZEUS pipetting channel includes an integrated Z-Axis withbuilt-in aspirate and dispense algorithms that coordinate movements,liquid classes, container geometries, and error handling. The ZEUSfamily of pipetting modules is designed for integration into instrumentationrequiring on-board pipetting. They perform single sample transfersand multiple dispenses (e.g., aliquoting) from 1 μL to 1 mL withthe highest precision and accuracy. The ZEUS Pipetting Modules utilizeHamilton’s revolutionary air displacement pipetting technologyand CO-RE™ (compressed O-ring expansion) tips. |

*Pipetting specifications were determined gravimetrically using a high precision balance and strictly controlled environmental conditions: test temperature: 20 ± 2°C, relative humidity: 50% ± 5%, test liquid temperature range: ≤± 0.5°C of room temperature; balance used: Mettler Toledo MX5.
The measurements were done with Hamilton Verification Solution (deionized water with 0.1% NaCl and 0.01% Tween detergent) using standard CO-RE conductive tips. A new tip was used for each pipetting cycle (aspiration and dispense). At least 10 points were taken for each volume and pipetting module. Volumes >20 μL were dispensed in jet mode. Volumes ≤20μL were dispensed in surface mode. Results may vary using other liquid or environmental conditions.
