## How to Choose an Automated Liquid Handler

Selecting the right liquid handling workstation depends on your workflow requirements, throughput targets, and laboratory infrastructure. Key factors to evaluate:

**Throughput and run volume.** Estimate your daily plate output and whether you need unattended overnight operation. High-throughput screening labs typically require 96- or 384-channel heads and integrated plate hotels, while lower-throughput genomics workflows may be well served by an 8-channel or span-8 system.

**Deck capacity.** Count the number of deck positions required for tips, reagent reservoirs, labware carriers, and integrated instruments. Larger decks support more complex workflows but require more bench space.

**Pipetting volume range.** Confirm the minimum and maximum aspiration volumes for your assay. NGS library prep and low-volume compound handling require accurate sub-microliter dispensing; ELISA and normalization workflows typically operate in the 10–200 µL range.

**Channel count and head configuration.** Single-channel, 8-channel, 96-channel, and span-8 heads each offer different throughput and flexibility trade-offs. Some platforms support interchangeable heads.

**Disposable tips vs. fixed tips.** Disposable tip systems reduce cross-contamination risk and are standard for most life science workflows. Fixed-tip systems (common in acoustic and some positive-displacement platforms) require wash steps between transfers.

**Labware compatibility.** Verify that the system supports your plate formats, tube types, and reservoir configurations. Confirm tip compatibility with your preferred tip vendor.

**Grippers and plate movement.** Integrated gripper arms allow automated plate transport between deck positions and integrated instruments. Confirm gripper reach and compatibility with your labware stack heights.

**Onboard accessories.** Barcode readers, tip counters, liquid-level sensing, and integrated shakers or heating/cooling modules vary by platform and configuration.

**Scheduling software and integration.** Evaluate the method development environment, scripting complexity, and compatibility with your LIMS, scheduling software, and any integrated instruments such as plate readers, centrifuges, or sealers.

**Footprint and serviceability.** Confirm bench dimensions and weight capacity. Consider local service availability and spare parts access for the platform you select.

## Automated Liquid Handler Types

### Air-Displacement Pipetting Workstations

Air-displacement systems are the most common platform in life science laboratories. They use a sealed air column to aspirate and dispense liquid, with disposable tips to prevent cross-contamination. Platforms such as the Beckman Coulter Biomek series, Hamilton Microlab STAR, Tecan Freedom EVO, and Eppendorf epMotion use air-displacement pipetting. These systems are well suited for genomics, proteomics, ELISA, normalization, and general sample preparation.

### Positive-Displacement / Specialized Pipetting

Positive-displacement systems use a piston in direct contact with the liquid, making them suitable for viscous, volatile, or high-density samples where air-displacement accuracy is compromised. Some platforms offer positive-displacement heads as optional accessories.

### Acoustic Liquid Handling

Acoustic liquid handlers use focused sound energy to transfer nanoliter-to-microliter volumes without tips, eliminating tip costs and cross-contamination risk. The Beckman Coulter Echo 525 and Echo 650 are acoustic platforms commonly used for compound management, assay miniaturization, and DMSO-based transfers. Acoustic systems are not suitable for all liquid types and require compatible source plate formats.

### Integrated Robotic Workstations

Some liquid handling platforms are designed as the central component of a larger robotic workcell, with robotic arms, plate hotels, incubators, readers, and sealers integrated around a central scheduler. The Hamilton STAR and Tecan Freedom EVO are frequently configured as workcell hubs. These systems offer the highest throughput and automation depth but require more complex method development and infrastructure.

## Automated Liquid Handlers vs Manual Pipetting

Automated liquid handlers and manual pipetting each have a role in laboratory workflows. The right choice depends on throughput, reproducibility requirements, budget, and assay complexity.

**Throughput.** Manual pipetting is practical for low-volume, low-frequency tasks. Automated systems become cost-effective when processing dozens to hundreds of plates per week, or when run frequency justifies the capital investment.

**Reproducibility.** Automated systems eliminate operator-to-operator variability in pipetting volume, timing, and technique. This is particularly important for quantitative assays, NGS library preparation, and regulated workflows where inter-operator variability must be controlled.

**Operator variability and ergonomics.** Repetitive manual pipetting carries ergonomic risk. Automation reduces operator fatigue and the associated variability in high-volume workflows.

**Method setup.** Automated systems require upfront method development and validation. Simple workflows can be programmed quickly on most platforms; complex multi-step protocols require more development time.

**Flexibility.** Manual pipetting is more flexible for ad hoc, low-volume, or highly variable tasks. Automated systems are optimized for defined, repeatable workflows.

**Capital cost.** Automated liquid handlers represent a significant capital investment. Used and refurbished systems can substantially reduce acquisition cost while delivering the same workflow capability.

**Validation burden.** Regulated laboratories (GMP, GLP, CAP, CLIA) must validate automated liquid handling systems before use. Validation requirements vary by regulatory framework and intended use.

## Buying Used and Refurbished Liquid Handlers

Used and refurbished automated liquid handlers can deliver significant cost savings compared to new systems. When evaluating a pre-owned system, consider the following:

**Pipetting head condition.** Inspect or request documentation on pipetting accuracy and precision. Tip eject function, seal integrity, and piston condition affect pipetting performance.

**Deck alignment.** Confirm that deck positions are correctly calibrated and that labware carriers seat properly. Misalignment can cause tip pickup failures and liquid transfer errors.

**Liquid-level sensing.** Many platforms include capacitive or pressure-based liquid-level sensing. Confirm that sensing hardware is present and functional if required for your workflow.

**Tip compatibility.** Verify that the system is compatible with your preferred tip vendor and that tip adapters or racks are included or available.

**Gripper function.** If the system includes a gripper arm, confirm range of motion, grip force, and compatibility with your labware.

**Accessories and modules.** Confirm which accessories are included: barcode readers, tip counters, heating/cooling modules, shakers, and integrated instruments vary by configuration.

**Software and licensing.** Control software, method files, and licenses vary by platform and may require transfer or repurchase. Confirm software version compatibility with your operating system and any integrated instruments.

**Computer and controller.** Some systems include a dedicated controller PC. Confirm OS version, hardware compatibility, and whether the controller is included.

**Service history.** Where available, request service records, PM documentation, and any calibration or qualification records. Not all used systems will have complete documentation.

**Calibration and qualification.** Regulated laboratories should plan for IQ/OQ/PQ upon installation. mLab Supply does not guarantee that every system has been calibrated or qualified to a specific standard prior to sale.

**Included labware carriers.** Confirm which plate carriers, tube carriers, tip racks, and reservoirs are included with the system.

## Software, Methods, and Integration

Software and licensing are critical considerations when purchasing a used automated liquid handler.

**Control software.** Each platform uses proprietary control software (e.g., Biomek Software, Hamilton Run Control, EVOware, epBlue, VWorks). Confirm the software version included with the system and whether it is compatible with your operating system.

**Method files.** Existing method files may be transferable with the system, but compatibility with your specific configuration and software version should be verified.

**Licensing.** Software licenses vary by platform. Some licenses are tied to the instrument serial number; others require separate purchase or transfer. Confirm licensing terms before purchase.

**Computer compatibility.** Some systems require a specific controller PC or OS version. Confirm hardware and OS requirements for the software version included.

**LIMS integration.** Many platforms support LIMS connectivity via barcode scanning, file-based data exchange, or direct API integration. Integration requirements vary by LIMS and platform.

**Scheduling software.** Workcell configurations may require scheduling software (e.g., Momentum, SAMI, Overlord) in addition to the liquid handler control software. Confirm whether scheduling software is included and licensed.

**Buyer IT requirements.** Confirm network connectivity requirements, firewall rules, and IT security policies before installation, particularly for systems that connect to LIMS or scheduling platforms.

Software and license availability vary by system and configuration. Contact mLab Supply to confirm what is included with a specific listing.
