The Key to Laboratory Automation – A Focus on Hardware

The future of laboratory automation starts now.

Laboratory automation is no longer a futuristic vision – it is already transforming the way laboratories operate. While fully autonomous "dark laboratories," based on the concept of the dark factory, are still under development, numerous technological advancements are already making laboratories more efficient, cost-effective, and productive. Some of these solutions have long since moved beyond the prototype stage and are successfully deployed in modern laboratories.

But what exactly does laboratory automation mean? Essentially, it's about replacing repetitive and error-prone processes with smart technology – from pipetting robots to highly complex analytical systems that can independently process samples and evaluate measurement results. AI in the lab expands these possibilities even further: it enables not only automation but also intelligent, data-driven decision-making.

This article is the first part of a series on laboratory automation and focuses on the role of hardware. We show which devices are already optimizing processes today, how they contribute to increased efficiency and accuracy, and which technologies will prevail in the future.

But laboratory automation is more than just technology – it requires a well-thought-out strategy. In the following sections, we will not only examine existing automation options, but also two strategies for successful implementation: incremental automation and complete automation from the outset.

Laboratory automation today: Which technologies are already in use

Even today, automated laboratory equipment offers tremendous opportunities to make work processes more efficient and optimize routine tasks. Automated systems are already established in many areas, contributing to improved accuracy, reduced workload, and better utilization of laboratory resources. Therefore, laboratory automation and modern technologies should be considered in any laboratory that prioritizes long-term efficiency.

Selecting the right hardware is a crucial factor. Analytical instruments, pipetting robots, and fully automated sample preparation systems already automate many work steps, enabling seamless process optimization in the laboratory. Beyond pure functionality, user-friendliness, ease of maintenance, and integration capabilities with existing systems are essential to fully exploiting the potential of these technologies.

‍

The following automation options are already an integral part of many laboratories and demonstrate what is already possible in laboratory automation:

• Liquid handling and sample preparation robots:These devices are specialized in automating precise and repeatable pipetting as well as complete sample preparation steps. A leading company in the automation of complete laboratory workstations is [Company Name]. Axel-Semrau GmbH(by Trajan) from Sprockhövel. Axel Semrau specializes in fully automating complete analytical tasks, often involving routine analyses such as FAME, MOSH, PAH, or glyphosate. The use of such systems allows laboratories to save considerable resources and significantly increase efficiency.

• Automated analysis systemsHPLC (MS) and GC (MS) instruments represent the gold standard in many laboratories and are equipped with numerous smart features that partially automate analytical processes. For example, some of these HPLC models offer the ability to perform derivatization steps or standard dilutions directly in the autosampler. These functions allow complex analyses to be performed automatically, significantly reducing data acquisition time and utilizing labor more efficiently. This automation contributes considerably to increasing the accuracy of results and leads to significant savings in time and effort. Typical manufacturers of high-quality HPLC models include, among others... Shimadzu Corporation , Agilent Technologies and Thermo Fisher

• Dissolution testers in pharmaceutical research and quality control:In pharmaceutical research and development, as well as in quality control, automated release instruments are crucial for increasing efficiency and optimizing workflows. These instruments, often directly coupled to high-performance liquid chromatography (HPLC) or a UV spectrometer, automate the analysis of drug release from pharmaceutical formulations. This direct coupling eliminates the need for manual sample preparation by laboratory technicians, resulting in significant time savings. Every step that would have required manual pipetting into individual vessels is automated, saving valuable working time and accelerating the analysis process. Leading manufacturers such as Sotax,They offer state-of-the-art solutions designed not only to improve test accuracy but also to significantly reduce the overall turnaround time for sample preparation and analysis. These systems are essential for the efficient execution of routine analyses and ensure that quality control is carried out efficiently in compliance with regulatory standards.

‍

In addition to commonly used and standardized hardware, trends toward complete automation are increasingly emerging. These developments include:

‍

• Robotics and automated sample transport systems:Robotics and automated sample transport systems are becoming increasingly important in modern laboratories. These technologies, used for handling and transporting samples between different analysis stations, are indispensable in the laboratories of the future. They automate critical processes, reduce the need for manual intervention, and shorten turnaround times, thereby increasing efficiency and accuracy while minimizing the potential for errors. It should be noted, however, that such extensive automation projects are almost always custom-built.

‍

A brief glimpse into the future:In specific analytical fields, comprehensive sample preparation systems play a crucial role. These sophisticated systems not only perform standard tasks such as pipetting but also integrate centrifugation and derivatization functions. By automating and optimizing the sample preparation process, they significantly contribute to increasing the efficiency and accuracy of subsequent analyses. Although these systems, due to their complexity, cannot be integrated as easily as an HPLC system, they are nevertheless gaining market acceptance. It is highly likely that such systems will take over a large portion of routine laboratory work in the future, as they can replace human labor in many areas.

Laboratory automation: Overcoming challenges, leveraging advantages

Automating a laboratory is a complex undertaking involving significant preparation, high costs, and technical modifications. It also often requires restructuring workflows, which represents a major adjustment for laboratory staff. For these reasons, many laboratories hesitate to implement automation projects, even though the long-term benefits can be enormous.

In this section, we highlight the key advantages of laboratory automation and demonstrate the concrete benefits that automated systems offer in terms of efficiency, accuracy, and resource optimization. We also present two strategic approaches for automating laboratories in a targeted and efficient manner, without unnecessarily disrupting operations or wasting resources.

‍

The most important advantages of laboratory automation

Laboratory automation offers numerous advantages that significantly simplify daily work. While the transition may initially require some effort, the investment pays off in the long run – both financially and in terms of efficiency and quality. Intelligent process automation not only saves time and resources but also improves accuracy and safety in the laboratory.

Here is an overview of the biggest advantages:

‍

1️⃣ Increased productivity & time savings

Challenges of laboratory automation

Laboratory automation offers enormous advantages, but it is not without challenges. Many laboratories hesitate to implement it because switching to automated systems not only represents a financial investment but also requires profound changes to workflows.

Here are some of the biggest challenges that laboratories face on their path to automation:

‍

High initial investments

Acquiring automated laboratory equipment often requires a significant capital investment. In addition to the equipment costs, training, maintenance, and integration into existing systems must also be considered. Smaller laboratories, in particular, face the challenge of implementing automation in a cost-effective way without exceeding their budget.

Gradual automation can help spread investments and minimize risks. Instead of converting the entire lab at once, it's worthwhile to start with individual processes that are particularly time-consuming or error-prone.

‍

Complexity of integration into existing systems

Many laboratories use different analytical methods and manufacturer systems that are often not directly compatible. Data formats, control protocols, and interfaces can vary significantly, making the seamless integration of new automation solutions difficult.

Modular systems and standardized interfaces, such as LIMS-compatible devices, facilitate networking and ensure better scalability. Those opting for new technologies should ensure that they can be integrated into existing structures and do not lead to isolated, standalone solutions.

‍

Acceptance and adaptation within the team

Automation not only changes processes but also the demands placed on staff. Some employees fear that automation will replace their jobs, while others have to adapt to new systems they may not immediately master. Furthermore, a flawed implementation can initially reduce efficiency if processes are not yet running smoothly.

Early team involvement, targeted training, and clear communication help reduce uncertainty and foster acceptance. Automation is not intended to replace staff, but rather to relieve them by taking over routine tasks and freeing up capacity for more demanding activities.

‍

Maintenance and reliability

Automated systems are powerful, but they require regular maintenance and can disrupt the entire workflow if they fail. A single malfunction can have far-reaching consequences if no contingency plan is in place.

Predictive maintenance with AI-supported fault analysis can minimize downtime by detecting problems early, before they lead to major disruptions. Additionally, laboratories should always have backup strategies in place for critical processes to ensure a flexible response in case of an emergency.

‍

Scalability and future-proofing

Automation solutions must be future-proof. What works perfectly today could be obsolete in just a few years due to new standards or technologies. Those who commit too early to proprietary or non-expandable systems risk losing flexibility in the long run.

Modular and cloud-based solutions offer greater adaptability and are easier to expand. In the long term, the integration of AI can help to adapt to new developments more quickly and to continuously improve automation solutions.

‍

Particularly critical aspects of comprehensive laboratory automation

A particularly challenging aspect of complete laboratory automation is automated sample movement – ​​that is, the entire process chain from sample preparation to transfer into the respective sample container and on to the autosampler of the corresponding analysis system.

In many routine laboratories, sample preparation varies depending on the instrument and analytical method, making a standardized, fully automated solution difficult at present. Currently, any laboratory automation system would need to rely on standardized sample containers, defined volumes, and uniform sample handling protocols to enable seamless automation.

‍

Another problem: The gradual loss of knowledge

With increasing automation, the demands on technical understanding and system maintenance also rise. The more complex laboratory processes become, the more essential it is that knowledge is captured in a structured manner and remains available long-term. However, this is precisely one of the greatest challenges facing modern laboratories: valuable know-how is lost, whether through the departure of experienced specialists, inadequate documentation, or insufficiently structured handovers.

This is a recurring problem, especially in highly specialized laboratories. Often, there is no centralized knowledge management system, and important information is passed on verbally or through unofficial channels. As a result, critical system configurations, maintenance cycles, or troubleshooting procedures are known to only a few employees. If one of these experts leaves the company, gaps remain that must be painstakingly filled.

Missing documentation means:

📌 Longer onboarding times for new or changing employees

📌 Increased susceptibility to errors, as specific system knowledge is not systematically passed on.

📌 Inefficient maintenance, made more difficult by unclear specifications and missing protocols.

📌 Dependence on individual experts, which means critical knowledge is not widely available

‍

Modern equipment management systems offer a solution, such as... LabThunderThese systems automatically maintain all technical logbooks, document maintenance processes, and ensure complete traceability. They not only help laboratories analyze errors more quickly but also safeguard the team's experience in the long term.

‍

Why is this so important?

🔹 Automated systems require regular maintenance – without sound knowledge, the risk of unplanned failures increases.

🔹 Laboratory processes and systems are constantly changing – flexible, digitized knowledge ensures continuous optimization.

🔹 New employees or changing teams can be trained more quickly without losing valuable time.

‍

In the future, no automated laboratory will be able to ignore this issue. Sustainable digitalization of knowledge management is just as crucial as the automation of physical laboratory processes. Only those who manage both technology and know-how equally will remain competitive in the long run.

‍

Conclusion: The future of laboratory automation is now.

Laboratory automation is no longer a vision of the future – it's a reality and is developing rapidly. Modern technologies enable laboratories to work more efficiently, reduce costs, and minimize potential errors. Automation offers a clear advantage, particularly in routine processes, by taking over repetitive tasks, increasing productivity, and improving the quality of results.

However, the path to automation requires strategic planning. High initial investments, integration challenges, and team acceptance are key hurdles that must be overcome. While gradual automation relieves the burden on laboratories and makes them more adaptable, a complete redesign can ensure maximum efficiency in the long run. The choice of the right strategy depends on the individual requirements of the laboratory.

A crucial factor that is often overlooked is the availability of knowledge. With increasing automation, the need for technical expertise to maintain and optimally utilize systems grows. Inadequate documentation and a lack of knowledge management can hinder automation progress. Solutions such as digital equipment management systems like LabThunder help preserve valuable expertise and make it accessible to all employees.

Automation is more than just technology – it's a transformation in the laboratory world. Laboratories that adopt smart systems early on and systematically digitize their knowledge not only secure competitive advantages but also actively shape the future of laboratory work.
