Hamilton Z-Excursion Universal Sampler (ZEUS) is a fully automated, self-contained, and ready-to-go pipetting module for integration into Diagnostics and Life Science instruments. It is based on Hamilton’s revolutionary air displacement pipetting technology and uses disposable tips to avoid carry-over. The module is equipped with Qualitative Pipette Monitoring (QPM) which ensures precise and secure pipetting.

ZEUS

The ZEUS pipetting channel is a complete pipetting module with an integrated Z-Axis.

ZEUS LT

The ZEUS LT pipetting channel is designed for mounting to an existing Z-Axis.

Disposable Tips

Hamilton offers a wide range of pipette tips to address a variety of common automation challenges.

What is On-Board Intelligence?

ZEUS has built-in algorithms for standard and advanced pipetting tasks

Automation engineers looking to integrate pipetting components have traditionally had to invest significant effort into developing algorithms to coordinate a myriad of factors.

To address these project risks, Hamilton designed the ZEUS pipetting family with on-board intelligence for industry-leading precision and accuracy.

Qualitative Pipette Monitoring (QPM)

On the STAR Liquid Handling Platform Hamilton pioneered the art of translating pressure curves into intelligent actions. With ZEUS, the benefit of this knowledge is available for integration into any liquid handling application. Some pipetting modules are capable of reporting pressure data, but ZEUS is the only one capable of interpreting the data and providing actionable information back to the system.

Clogged Tip Detection

If the tip clogs during aspiration the pressure will spike down. As the plunger moves, sample is not being aspirated to help equalize the pressure.

Insufficient Liquid Detection

If there is insufficient liquid in the tube, the pressure curve will start down as normal but then will return to a pressure much higher than the expected level represented by Δp in the graph. The higher pressure is a result of having less liquid in the tip due to an incomplete aspiration.

Aspiration of Foam

If ZEUS pipettes foam instead of liquid, the pressure sensor detects spikes during the aspiration. Based on the severity of the spikes, a threshold can be set for a failed aspiration.

Anti-Droplet Control (ADC)

Volatile liquids like acetone and methanol can be extremely difficult to pipette using air displacement. These liquids tend to vaporize in the tip which raises the air pressure resulting in liquid dripping from the tip. ZEUS is equipped with Anti-Droplet Control (ADC). When enabled, the pressure is monitored in the tip. As the pressure rises, the piston is retracted to equalize the pressure and prevent dripping. The illustrations show the pressure curve when ADC is on and off.

ADC OFF

Pressure reaches a maximum; a droplet is lost and pressure drops.

ADC ON

Piston retracts when pressure threshold is reached so no droplet forms.
