Automated Liquid Handlers (ALH)

Automated Liquid Handlers

Few laboratory workflows can function without pipetting. Whether preparing a PCR reaction, dosing reagents for an ELISA test, or filling microplates for screening experiments – precise and reproducible liquid handling is essential for reliable analyses.

However, this routine task is time-consuming, monotonous, and prone to error. Even the slightest deviations in volume or contamination can distort results and compromise experiments. As sample volumes increase and demands for standardization grow, manual pipetting processes quickly reach their limits.

Automated Liquid Handlers (ALH) play a key role here. They automate pipetting steps, relieve personnel from repetitive tasks, and ensure both precision and reproducibility. As a result, they form the backbone of many modern laboratory processes – from molecular biology and pharmaceutical research to clinical diagnostics.

Functions, Technologies, and System Types

Automated Liquid Handlers are much more than simple pipetting robots. They combine various technologies and configurations to handle liquids reliably, quickly, and reproducibly across a wide range of volumes.

Integration into Laboratory Workflows

Modern liquid handling robots are not stand-alone instruments but integral parts of complete workflows. They can be combined with additional modules for extraction, sample preparation, or temperature control and are managed by software that handles protocol execution and result documentation. The result is a continuous, standardized process from sample preparation to analysis.

Fields of Application

Automated Liquid Handlers are used in virtually every area of modern laboratory work. They are indispensable wherever large numbers of samples must be processed quickly, reliably, and with precision.

Molecular Biology and Genetics

In molecular biology laboratories, automated liquid handling has long been standard. Typical applications include:

• PCR and qPCR setups
• ELISA assays
• Next Generation Sequencing (NGS)
• Nucleic acid isolation

Reproducibility is particularly crucial for DNA and RNA analyses. Systems such as the CyBio FeliX Extraction Set combine precise liquid handling with automated nucleic acid extraction, enabling efficient processing of large sample batches.

Pharmaceutical Research and Screening

In drug research, thousands of substances must be tested quickly and reliably. High-throughput screening (HTS) forms the basis for identifying new active ingredients. Automated liquid handlers perform pipetting processes in 96-, 384-, or even 1536-well formats.

In addition to classic screening assays, they are also used in cell-based applications, such as the preparation and treatment of cell-based assays that simulate complex biological reactions. An example of this area are systems such as the CyBio Well vario, which are designed for simultaneous pipetting on a very large scale, thereby significantly accelerating screening processes.

Diagnostics and Clinical Laboratories

Automation also plays a key role in clinical diagnostics. Standardized pipetting processes ensure that samples such as blood, serum, or plasma are prepared reproducibly – a critical factor for reliable diagnoses. Compact systems like the CyBio SELMA series are particularly advantageous, as they integrate easily into existing workflows and enable fast, error-free processing of entire microplates.

Chemical and Industrial Applications

Beyond life sciences and diagnostics, chemical and industrial laboratories also benefit from automated liquid handling. Here, the focus is often on precise sample preparation for analytical procedures or materials research. Flexible platforms such as the CyBio FeliX series offer modular configurations that can accommodate a wide range of applications – from sample preparation to screening assays.

Academic Research and Education

Automated pipetting systems are not limited to high-end industrial or pharmaceutical environments. They are increasingly being adopted in university laboratories, where they simplify routine tasks, ensure reproducible results, and provide researchers with more freedom for creative work. Compact designs and modular concepts make ALH systems accessible even for smaller institutions.

Advantages of Automated Liquid Handling

The introduction of Automated Liquid Handlers is transforming laboratory workflows. They relieve personnel, improve data quality, and free up capacity for more demanding tasks.

Key advantages include:

• Efficiency and time savings: Multiple samples or entire plates can be processed in parallel. Routine operations run automatically, dramatically reducing project turnaround time.
• Precision and reproducibility: Pipetting steps are executed with standardized accuracy – a critical factor for analyses at nano- to microliter scales.
• Safety and reliability: Automation reduces contamination risk and minimizes variability caused by manual handling.
• Flexibility: From compact devices for smaller sample numbers to high-throughput systems, solutions can be tailored to specific requirements. Modular platforms such as the CyBio FeliX series grow with laboratory needs and protect long-term investments.
• Sustainability: Optimized workflows use consumables and reagents more efficiently, lowering costs and conserving resources.

Automated Liquid Handling is therefore not just a convenience but a decisive competitive factor. Laboratories that embrace automation are better equipped to manage rising sample volumes while maintaining the highest standards of quality and safety.

Challenges and Trends

While Automated Liquid Handling offers numerous benefits, it also presents new challenges. Laboratories implementing such systems must consider not only the technology itself but also organizational and economic factors.

Key challenges include:

• Investment costs: Initial acquisition can be substantial but often pays off quickly through higher efficiency, reduced labor, and fewer repeat tests.
• Training and acceptance: Personnel must be properly trained to operate and maintain the systems effectively.
• Integration into existing workflows: Full potential is realized only when systems are seamlessly connected to analytical instruments and laboratory databases.

Emerging developments and trends are also shaping the Automated Liquid Handling market:

• Miniaturization and modularity: Systems are becoming smaller, more flexible, and better suited to varying requirements – from semi-automated assistants like CyBio SELMA to highly modular platforms like CyBio FeliX.
• Artificial intelligence (AI): AI-driven systems can optimize workflows, detect potential errors early, and intelligently manage resource usage.
• Lab 4.0 and digital integration: Automated Liquid Handlers are increasingly part of connected laboratory ecosystems, enabling full process traceability and regulatory compliance.
• Sustainability: Reduced consumption of tips, reagents, and energy is becoming a key focus – both economically and environmentally.

This shows that Automated Liquid Handling is not only a response to today’s requirements but also a driver of innovation that will shape the future of laboratory work.

Summary – ALH as a Key Technology

Automated Liquid Handlers have become an indispensable part of modern laboratory work. They perform not only repetitive pipetting tasks but also provide the foundation for precise, reproducible, and efficient analyses across disciplines – from molecular biology and pharmaceutical research to clinical diagnostics and industrial analytics.

Practical examples illustrate the breadth of applications:

• CyBio FeliX extraction set – for high-throughput nucleic acid extraction in molecular biology applications.
• CyBio FeliX series – a modular platform adaptable to diverse workflows and laboratory environments.
• CyBio SELMA series – compact, semi-automated assistants for fast routine operations using 96- or 384-well plates.
• CyBio Well vario series – designed for large-scale high-throughput screenings with up to 1536 pipetting channels.

This diversity shows that Automated Liquid Handling is not merely a technological option but a key to future laboratory performance. Those who adopt automation gain efficiency, reliability, and the ability to meet rising demands for quality, standardization, and sustainability.
