Laboratories worldwide face mounting pressure to enhance efficiency and throughput while maintaining accuracy and precision critical to scientific research. Additionally, they must adapt to the ever-changing scientific and operational demands driven by rapid advancements in technology, evolving research priorities, and increased regulatory requirements. In the United States alone, over 14 billion laboratory tests are processed annually. Despite this high demand, the industry faces severe staffing shortages, with vacancies ranging from 7% to as high as 25%. This understaffing can lead to increases in workloads, contribute to employee burnout, and raise the risk of errors in testing processes [1]. To address these challenges, labs must implement solutions that future-proof their operations, ensuring long-term adaptability, employee satisfaction, and the ability to remain competitive. As lab automation continues to drive innovation, it provides a solution to address challenges faced by laboratories. By automating labor-intensive and repetitive tasks, labs can improve efficiency, streamline workflows, and enable staff to focus on more complex, analytical work. Automation also delivers a strong return on investment by reducing operation costs associated with human error, optimizing resource usage, and ensuring greater reliability and consistency in results.
Before exploring how to futureproof laboratories, it is essential to examine the current challenges they face. As previously noted, the increasing demand for testing in understaffed labs places enormous pressure on both organizations and their personnel. These pressures result in several operational bottlenecks that impact the speed, accuracy, precision, and cost of laboratory results.
The first bottleneck lies in the inefficiencies and inconsistencies of manual workflows. Processes such as sample preparation, data entry, and pipetting are time consuming, requiring significant resources while being prone to human error.. Furthermore, when multiple scientists work on the same assay, variations in techniques – such as pipetting methods, reagent volumes, or incubation times – further amplify inconsistencies. This combination of inefficiency and variability impacts the reproducibility and reliability of results, ultimately hindering the lab’s ability to deliver consistent outcomes.
The second is the difficulty of transitioning to higher throughput. Laboratories face increasing demands to process more samples within a limited timeframe without comprising quality. Running multiple assays across multiple plates simultaneously can overwhelm individual scientists, further straining their capacity to deliver timely and accurate results.
The last bottleneck is the high cost of maintaining accuracy and precision. Reliance on manual workflows inflates operational expenses and reduces profitability. Errors, which are inevitable in manual processes, come with steep costs in terms of wasted time and resources due to reruns or corrections. These challenges highlight the pressing need for innovative solutions to improve laboratory efficiency and outcomes. In the next section, we will explore how automation addresses these obstacles and serves as a key strategy for future-proofing labs.
Laboratory automation is reshaping the way modern labs operate by introducing innovative technologies that streamline operations and enhance efficiency. Borrowing concepts from the manufacturing industries, it empowers scientists to delegate repetitive, time-consuming manual tasks to automated systems without compromising the accuracy or integrity of their results.
At its core, laboratory automation integrates different instruments, each specialized for a particular task, into a unified system. These systems are driven by protocols defined by the user, dictating the sequence of operations and the movement of resources, such as microplates or petri dishes. Once fully configured, an automated system can operate continuously, performing tasks around the clock with minimal human intervention—pausing only for routine preventative maintenance or error resolution.
Automation directly addresses laboratory bottlenecks. By automating repetitive tasks, it enables simultaneous execution of multiple steps. Each stage of the process, from sample preparation to incubation and data analysis, is precisely controlled, virtually eliminating errors. Automation also standardizes workflows, ensuring every step is executed with precision, thereby guaranteeing consistency and reproducibility across experiments.
For labs requiring higher throughput, automation offers transformative benefits. It allows the simultaneous processing of multiple assays and plates, drastically increasing sample throughput. Furthermore, dynamic scheduling ensures instruments are optimally utilized, with minimal downtime as plates are queued and processed efficiently.
While automation involves a significant upfront investment, its long-term return on investment is compelling. By reducing human errors and enabling labs to process more samples in less time, automation drives profitability and operational sustainability. As we’ll explore in the next section, these financial advantages make automation an indispensable consideration for labs aiming to future-proof their operations.
A compelling case study conducted by the Fraunhofer Institute for Production Technology in Aachen, Germany highlights the transformative potential of automation in the production of induced pluripotent stem cells (iPSC). The study focused on developing a fully automated system to handle processes such as cell seeding, medium exchange, and cell monitoring. The findings revealed significant operational and financial advantages of automation over manual workflows.
Operationally, the automated system demonstrated enhanced batch-to-batch consistency, overall accuracy of the results, and reduced error rates compared to manual production. Financially, the cost of manually producing 231 iPSC cell lines per year over an eight-year period amounted to $7.3 million. In contrast, the automated system achieved the same output at a total cost of $4.2 million including the initial system investment – a reduction of 42%. The most significant cost disparity lay in personnel expenses, which accounted for 60% of the total cost in manual production but only 16% in the automated system.
The study also analyzed the return on investment (ROI), an indicator of a business’s profitability. The ROI for manual production peaked at 117% by the third year but declined to 89% by the eighth year, indicating a loss in profits. Conversely, the automated system achieved a maximum ROI of 215% by the sixth year and maintained a ROI above 200% after eight years, highlighting its long-term financial benefits.
Another noteworthy metric is the payback period – the time required to recover the initial investment. While manual production had a shorter payback period of 0.65 years compared to 0.84 years for automation, this short-term advantage was outweighed by the significant long-term profitability of the automated system.
In summary, while manual production offers higher short-term returns, automation proves to be the more sustainable choice. By improving quality, consistency, and scalability while reducing overall costs, automation ensures not only operational efficiency but also robust financial returns in the long run.

Laboratory automation is no longer just a futuristic concept – it is a necessity looking to overcome current challenges and thrive in an increasingly competitive and demanding environment. By addressing the bottlenecks in manual workflows, such as the inefficiencies and inconsistencies of manual workflows, limited scalability, and rising operational costs, automation paves the way for improved consistency, accuracy, efficiency, and profitability. As seen from the case study on iPSC production, the long-term benefits of automation, in terms of cost savings, operational consistency, and return on investment, are significant and can drive sustainable growth and innovation in your lab.
