Over the past few years, we have seen more and more labs begin to adopt robotic pipetting systems and integrate them into their workflows1. This has provided scientists with several benefits over manual pipetting, including enhanced accuracy and precision and the capacity to perform workflows with higher throughput2. Additionally, robotic pipetting setups improve laboratory safety by minimizing exposure to hazardous substances and reducing the risk of typical lab injuries such as repetitive strain injury (RSI). Advanced cloud-based solutions have recently emerged as innovative tools for full workflow integration, further enhancing productivity and data integrity. Here, we will explore the impact of robotic pipetting on lab practices and provide insights into some key considerations to help you choose the right semi-automated pipetting system for your lab.
It’s no secret that with manual pipetting comes inherent human error, which can compromise the quality and integrity of resulting data3. Robotic pipetting systems curb this, enabling scientists to perform experiments with a far higher degree of accuracy and precision than manual systems. Automated pipetting systems measure volumes and dispense liquids far more accurately than manual pipettes. For example, DISPENDIX’s I.DOT Liquid Handler facilitates precise transfers down to 8 nL, while manual pipettes are prone to a high degree of error when pipetting volumes lower than 0.5-1 µL3. Robotic pipetting systems are often equipped with advanced features like automated liquid class calibration and volume verification, ensuring accuracy and precision across various liquids despite their inherent variability. This high level of precision is crucial in sensitive workflows, such as omics research, where even slight pipetting variations can significantly affect outcomes, making robotic pipetting an invaluable tool for achieving reliable, reproducible results4,5.
One of the most significant features of robotic pipetting systems is their ability to automate repetitive, monotonous tasks. This not only avoids the introduction of error but also frees up researchers for more strategic work that requires their high lab skill levels and scientific expertise. In addition, robotic pipetting setups provide researchers with the capacity for parallel processing, whereby they can handle multiple samples simultaneously, increasing throughput and allowing researchers to scale up assays. This is particularly advantageous in high-throughput screening (HTS), for example, when screening compound libraries in drug discovery (Fig. 1)6,7.

Repetitive manual pipetting goes hand in hand with the serious risk of RSI, which can be painful and uncomfortable, halting researcher productivity and detrimentally impacting other areas of their lives. Robotic pipetting systems can eliminate this risk by curbing the need for manual intervention. Moreover, automated workflows are advantageous for labs working with hazardous substances, such as toxins and pathogens, since they limit the exposure of lab personnel to these substances (Fig. 2). A study shed light on the benefits of a semi-automated workflow for tuberculosis testing, showcasing its ability to minimize manual sample handling and hands-on time, lowering the risk of exposure to potentially hazardous tuberculous samples and diminishing the chances of RSI8. These findings highlight the significant advantages of integrating semi-automated processes in medical testing environments, offering a safer and more efficient pathway for handling infectious samples and enhancing laboratory safety.

Recently, advancements in automated and semi-automated lab appliances have opened up the possibility of fully integrated, intelligent, automated workflows. These systems facilitate seamless data exchange and coordinated pipelines, drastically improving efficiency and reducing the potential for error. Furthermore, innovative cloud-based solutions for integrating automated systems have changed how scientists monitor and control their experiments, allowing for real-time adjustments and oversight from anywhere in the world. For example, the G.STATION’s DISPENDIX Cloud Platform enables scientists to monitor the status of their experiments remotely, design protocols and processes, and share them, facilitating more collaborative research and diagnostic efforts.
