However, one part of the laboratory has often remained surprisingly manual.

At the laboratory bench, scientists still follow paper-based Standard Operating Procedures (SOPs), manually transfer data between instruments and software, and spend valuable time recording results instead of focusing on science. This disconnect creates inefficiencies, increases the risk of human error and makes it more difficult to maintain complete data traceability.

The question for many laboratories is no longer whether to digitise. It is how to connect every part of the laboratory into one efficient and reliable digital environment.

That is where a Lab Execution System (LES) plays a critical role.

Data is not the challenge

Most laboratories already have the systems they need to manage samples and record scientific work. A LIMS provides end-to-end management of samples, analytical data, and quality records. An ELN enables scientists to document experiments, record observations and collaborate with colleagues.

Alongside these systems sits another essential part of the laboratory: the instruments that generate scientific data.

From balances and chromatography systems to spectrometers and PCR instruments, laboratories rely on equipment from multiple manufacturers. Each instrument often uses its own communicationprotocol and data format, making it difficult to exchange information automatically.

According to the Fraunhofer Institute, laboratories typically operate instruments from multiple manufacturers, making seamless communication between equipment and software one of the biggest challenges in laboratory digitalisation. The result is a disconnect between laboratory instruments and digital systems, leaving scientists to bridge the gap through manual data entry.

The issue is not a lack of technology. It is a lack of connectivity.

How the modern laboratory comes together

A laboratory is made up of several connected layers, each with a different purpose.

The information layer manages samples, experiments, documentation and reporting through systems such as LIMS and ELNs. These applications manage samples, experiments, documentation and reporting. The instrument layer includes the laboratory equipment that generates analytical and experimental data.

Between these sits the operational layer, where scientists carry out laboratory procedures, prepare samples, operate instruments and generate results.

This operational layer is where a Lab Execution System fits.

Rather than replacing existing laboratory software, an LES connects scientists, laboratory instruments and digital systems into one continuous workflow. It enables data to move automatically between the laboratory bench and the wider digital infrastructure while guiding scientists through every stage of the process.

More than SOPs

Many people think a Lab Execution System is simply a way to replace paper SOPs. While digitising procedures is an important capability, an LES delivers much more.

A modern LES guides scientists through laboratory workflows step by step, ensuring that procedures are followed consistently across teams, laboratories and locations.

At the same time, it automatically captures data directly from connected laboratory instruments as work is performed. This removes the need to manually record results before entering them into anothersystem.

The outcome is a more consistent laboratory process, improved data quality and complete traceability from start to finish.

Instead of asking scientists to adapt to disconnected systems, an LES brings systems together around the scientist.

Why connectivity matters more than ever

Digital transformation is delivering measurable benefits across laboratories, but only when systems are connected.

As laboratories continue to digitise, the ability of instruments and software to communicate has become just as important as the technologies themselves.

Yet connecting laboratory instruments and software remains a persistent challenge. Equipment is often supplied by different vendors, each using proprietary interfaces and data formats. Without commonstandards, integrating new devices can be slow, costly and difficult to scale.

This is why standards such as LADS (Laboratory and Analytical Device Standard), based on OPC UA, and SiLA 2, developed by the SiLA Consortium are becoming increasingly important. Although they take different approaches, both provide standardised methods for laboratory instruments and software to exchange information, reducing the need for bespoke integrations and making it easier to create connected laboratory environments.

These advances are about more than introducing new software. They depend on creating connected workflows in which data moves seamlessly between instruments, scientists and digital systems. As laboratories embrace automation and AI, these foundations will become increasingly important for improving efficiency, strengthening data integrity and enabling more flexible, scalable laboratory operations.

Without connectivity, laboratories continue to rely on manual processes that slow productivity and increase operational risk.

LES, LIMS and ELN each have a different purpose

One of the most common misconceptions is that a Lab Execution System replaces a LIMS or an ELN.

In reality, these systems work together.

A LIMS focuses on managing samples, tracking their progress through the laboratory and storing analytical results.

An ELN focuses on documenting experiments, recording scientific observations and supporting collaboration.

A Lab Execution System focuses on the execution of laboratory work itself. It guides scientists through workflows, connects laboratory instruments and captures data automatically as work is carried out.

Each system solves a different challenge, but together, these systems create a connected laboratory where information flows seamlessly between people, instruments and software.

Building a connected laboratory without replacing existing systems

The first step is understanding how existing systems communicate and identifying any gaps in connectivity.

A modern Lab Execution System can integrate existing laboratory instruments with LIMS, ELNs and other digital platforms, allowing laboratories to modernise while protecting previous technologyinvestments.

This approach reduces disruption, supports future growth and creates a scalable foundation for automation, artificial intelligence and advanced data analytics.

Modernisation is not about replacing what already works.

It is about connecting it.

Turning strategy into execution

The laboratories that will benefit most from digital transformation are not necessarily those with the newest technology, but those whose systems work together.

A Lab Execution System provides the missing operational layer at the bench, connecting scientists, laboratory processes, and instruments to enable more efficient and data driven workflows. As laboratories continue to invest in automation, artificial intelligence and digital transformation, this connected approach will become essential for improving efficiency, ensuring data integrity and supporting regulatory compliance.
