Intelligent Liquid Handling

For Better Results

MOVING LIQUID IS EASY; PRECISION LIQUID

HANDLING IS HARDInstrument manufacturers frequently underestimate the scope of their

liquid handling needs which results in cost overruns, product redesign, and delayed product launch. In an industry where state-of-the-art changes

rapidly, speed to market means the difference between market leadership and a failed product launch. Let us show you how our ZEUS® modules

can get your project done on time and on budget.

Typical pipetting components and their manufacturers place the burden of precision and accuracy on the integrator. Fortunately, the ZEUS is not like any other

pipetting channel on the market and Hamilton is not like any other partner. Hamilton takes ownership of the pipetting process and has developed

an air displacement pipetting module based on the industry leading pipetting technology in our STAR™ liquid handler.

Obtaining Accuracy through Air Displacement PipettingWHAT IS AIR DISPLACEMENT PIPETTING?Air displacement pipetting uses a piston to aspirate liquid into a disposable plastic tip. As the piston moves up, the air pressure in the tip is lowered and sample is pushed into the tip by the atmospheric pressure. With this method of pipetting, the sample only contacts the pipette tip which can be discarded between samples to eliminate cross contamination. ZEUS uses a solid state piston that improves performance and minimizes maintenance when compared to liquid filled air displacement systems.

Plunging the tip to a set height can overflow the vessel.

VESSEL OVERFLOW1

Inconsistent insertion of the tip results in excess liquid on the outside and impacts accuracy.

LIQUID FROM OUTSIDE OF THE TIP

3

Submerging the tip results in force, pushing liquid into the tip even when the plunger does not move.

OVER ASPIRATION2

Air is compressible. This creates challenges and makes achieving acceptable pipetting accuracy and precision difficult if all the variables are not considered and properly compensated for. Characteristics like density, surface tension, volatility, viscosity, and more all have an impact on pipetting accuracy. As seen below, aspirating from the surface of the liquid can also be an important consideration. Thankfully, ZEUS is designed to do all the thinking. Just enter the parameters and ZEUS handles the rest. If the proper parameters are unknown, Hamilton can even help with generating and validating liquid classes.

Not all samples are received with the same volume of liquid in the vessel. Pipetting from

a fixed height can result in significant inaccuracies. While Liquid Level

Detection (LLD) is common across pipetting components, ZEUS is

the only device that can actually find the surface of the liquid

by combining LLD with movement of the Z-Axis. Simple pipetting modules leave this up to the integrator which delays development timelines.

COMMON LLD ISSUES

WHY IS FINDING THE SURFACE OF THE LIQUID CRITICAL?

Liquid Level Detection

LLD requires a precise coordination between the pipette module and the Z-drive. Some pipette components claim LLD capabilities

when in reality all they provide is the raw capacitance or pressure output and the integrator is left with the real work. With simple high

level commands, ZEUS finds the surface of the liquid and positions the pipette accordingly, using capacitance (cLLD) for ionic solutions and a

pressure-based (pLLD) method for non-ionic solutions.5

■ Simplified component integration and decreased time to market

■ Reduced instrument maintenance and service with no valves, syringes or tubing required

What is ZEUS?ZEUS is a family of pipetting modules designed for integration into instrumentation requiring on-board pipetting. They perform single sample transfers and multiple dispenses (e.g., aliquoting) from 1 μL to 1 mL with the highest precision and accuracy. The ZEUS Pipetting Modules utilize Hamilton’s revolutionary air displacement pipetting technology and CO-RE™ (compressed O-ring expansion) tips.

ZEUS WITH INTEGRATED Z-AXISADDITIONAL BENEFITS & FEATURES

■ High level aspirate and dispense commands use liquid classes to synchronize pipette and Z-Axis movements to find the surface of the liquid and follow the liquid during pipetting according to the defined container geometry

■ The Z-Axis is strong enough to pierce foil or septa seals but delicate enough to detect a foil surface without leaving a mark

■ High resolution Z-Axis (0.1 mm) makes it possible to automatically teach critical deck locations with no operator interaction

■ Validated pipetting algorithms mean less time spent on pipetting and quicker product launches

Pipetting PerformanceGuaranteed

ZEUS has a small pressure sensor integrated into the pipetting channel. This monitors the pressure in the air space between the piston and the liquid. By correlating the pressure curve with the movement of the piston a standard curve for successful aspiration or dispensing can be established and deviations from this standard that affect the accuracy and precision can be detected. This process is known as Qualitative Pipette Monitoring.

WHAT DOES SUCCESSFUL PIPETTING LOOK LIKE?

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.

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.

PIPETTING VOLATILE LIQUIDS

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.

WHAT TYPES OF PIPETTING ERRORS ARE DETECTED BY QPM?Below are some examples of how the pressure curves for various common pipetting errors will look relative to a successful aspiration.

The measurements were done in 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 ≤ 20 μL were dispensed in surface mode. Results may vary using other liquid or environmental conditions.

Intelligent liquid handling for best results ZEUS (Z-Excursion Universal Sampler™) has been designed to take ownership of the entire pipetting process. It is based on Hamilton’s revolutionary air displace-ment pipetting technology and uses dis-posable CO-RE® tips to avoid carry-over.

With its integrated z-motion, ZEUS auto-matically picks up the tip, detects and follows the liquid level during aspiration and dispense. ZEUS adjusts its move-ments to the liquid type to ensure accu-rate and precise pipetting. The on-board Qualitative Pipetting Monitoring™ (QPM) actively prevents malfunctions. These high level capabilities allow customers to significantly shorten development time-lines and get product to market faster.

ZEUS LT is the lite version of Hamilton’s industry leading OEM pipetting module ZEUS.

The module enables OEM customers to incorporate a wide range of intelligent pipetting features into their instruments. The strongly reduced size allows an easy integration even for small instruments where space is a crucial criterion. Qualitative Pipetting Monitoring™ (QPM) or on-board liquid level detection are essential requirements for manufacturers of analytical instruments and clinical diagnostic systems. ZEUS LT captures these demands while allowing the freedom to operate with an individual z-axis.

This makes ZEUS LT the ideal candidate for instrument developers who do not require ZEUS’ integrated z-axis.
