Liquid Handlers

Liquid handling systems are automated laboratory instruments designed to accurately dispense, transfer, and manage liquids across a wide range of applications. Also known as automated liquid handlers or pipetting robots, these systems improve reproducibility, reduce manual error, and enable high-throughput workflows in research, clinical, and pharmaceutical laboratories.

At LabRepCo, we offer advanced liquid handling systems that support precision-driven workflows such as PCR setup, next-generation sequencing (NGS), drug discovery, and microplate-based assays. Whether you require a compact benchtop unit or a fully automated robotic platform, our solutions help streamline laboratory operations while maintaining consistent, reliable results..

What Is Automated Liquid Handling?

Automated liquid handling refers to the use of robotic systems to perform precise liquid transfers in laboratory workflows. These systems replace manual pipetting with programmable, repeatable processes that ensure consistent results across experiments.

Liquid handlers are commonly used to:

  • Dispense reagents and samples with high accuracy

  • Perform serial dilutions and plate replication

  • Prepare samples for molecular biology workflows

  • Automate repetitive lab tasks to improve efficiency

By minimizing human variability, automated liquid handling systems enhance data quality and reproducibility.

Types of Liquid Handling Systems

Understanding the different types of liquid handlers is essential when selecting the right system for your laboratory:

Benchtop Liquid Handlers

Compact systems designed for smaller labs or lower throughput workflows. Ideal for routine applications such as PCR setup and sample preparation.

High-Throughput Liquid Handling Systems

Designed for large-scale workflows, these systems support rapid processing of microplates and high sample volumes, commonly used in drug discovery and screening labs.

Modular Liquid Handling Platforms

Flexible systems that can be configured with additional modules such as robotic arms, incubators, and plate readers to create fully automated workflows.

Acoustic Liquid Handlers

Advanced systems that transfer liquids using sound waves instead of pipette tips, enabling ultra-low volume dispensing with minimal waste.

Applications of Automated Liquid Handlers

Liquid handling systems are widely used across multiple scientific disciplines:

  • PCR and qPCR Setup: Accurate reagent dispensing for molecular workflows

  • Next-Generation Sequencing (NGS): Library preparation and sample normalization

  • Drug Discovery: High-throughput screening and assay preparation

  • Cell-Based Assays: Reproducible liquid transfer for biological studies

  • Clinical Diagnostics: Standardized sample processing for testing workflows

These systems are essential for laboratories requiring speed, precision, and scalability.

How to Choose a Liquid Handling System

Selecting the right liquid handler depends on your workflow requirements and laboratory scale:

  • Number of Channels: Single-channel vs multichannel pipetting capability

  • Volume Range: Minimum and maximum dispensing volumes

  • Throughput: Number of samples processed per run

  • Deck Capacity: Ability to handle multiple plates, reservoirs, and labware

  • Automation Level: Standalone systems vs fully integrated robotic platforms

  • Software and Integration: Compatibility with LIMS and workflow automation tools

Choosing the correct configuration ensures optimal performance and long-term efficiency.
