Advancements
Over the past few decades, lab automation has made tremendous advancements through the integration of robotics, software, sensors and other technologies. Early automation equipment helped streamline routine tasks like sample handling and transportation within laboratories. However, modern Lab Automation now allows for fully automated sample preparation, analysis and data collection with minimal human intervention required. Sophisticated robotics are able to precisely manipulate samples, pipette reagents, operate laboratory equipment and record results. Cloud-based software coordinates the automated workflow and analyzes the data. This level of automation has massively accelerated experimental throughput while improving reproducibility and reducing human error.
Increased Efficiency and Throughput
One of the biggest benefits of lab automation is the dramatic improvements in lab efficiency and experimental throughput. Automated systems can work 24/7 with perfect reproducibility to process thousands of samples per day, versus just a few done manually. This high-throughput capability allows researchers to scale up experiments and collect much larger data sets over shorter time periods. Areas like drug discovery, genetics research and materials science have particularly benefited from this ability to rapidly screening of large libraries of compounds or sequences. The accelerated pace of experimentation translates directly into getting new discoveries and insights to market faster. Automated liquid handling stations and robotic arms have nearly eliminated waiting periods between experimental steps. Samples can be continuously processed without breaks.
Reduced Consumption of Reagents and Samples
Another advantage of lab automation is the reduction in consumption of valuable and often costly reagents and samples. Automated liquid handling provides much greater precision of pipetting volumes compared to manual methods. Very small amounts of reagents in the microliter range can be accurately measured and mixed. This minimizes waste from over-pipetting or evaporation. Sophisticated automated systems also offer non-contact liquid handling methods that avoid cross-contamination between samples. As a result, less sample and reagents are required to perform the same number of experiments compared to manual methods. For applications involving expensive assays, radioisotopes or rare clinical samples, automation helps stretch limited material budgets much further.
Improved Reproducibility and Consistency
Aside from efficiency gains, lab automation delivers more consistent and reproducible results compared to human-performed experiments. Automated liquid handlers, incubators and other equipment operate within tight specifications and tolerances without variances between users. Repeating the same multi-step protocol hundreds or thousands of times produces uniformly precise results each time. This high degree of consistency and reproducibility streamlines data analysis and allows for more reliable identification of true biological effects or outliers. It removes sources of experimental variability that can come from differences in pipetting technique, timing, ambient conditions or user errors between manually run trials. For applications like high-throughput screening, clinical diagnostics or industrial quality control procedures, automation delivers the gold standard of repetition with flawless reproducibility.
Simplified Workflow Tracking and Data Collection
Modern automated systems come bundled with informatic capabilities that greatly boost lab workflow management, data collection and analysis. Automation software coordinates the experimental protocol and records timestamps, instrument parameters, reagent additions and results from each process step. This data is automatically collated into comprehensive electronic lab notebooks linked to individual samples. Researchers gain real-time access and tracking of the entire multi-week or multi-month workflow from their computers or mobile devices. Data collection is paperless and integrated directly into Laboratory Information Management Systems (LIMS) and data analytics pipelines. Automation eliminates manual transcription steps prone to errors or omissions. It also allows integration of experimental results with other datasets like genomic sequences for combined "big data" analysis.
Reduced Personnel Requirements and Costs
While initial investment into automated lab equipment can be substantial, automation delivers significant long-term reduction in personnel and operational costs compared to maintaining manual labs. Less manpower is required to perform the same volume of experiments since robots replace humans for repetitive tasks like liquid handling, incubation and measurement steps. More senior scientists are freed from benchwork roles to focus on higher-level experimental design, analysis and management. Fewer researchers and technicians are needed to oversee multiple automated systems running in parallel versus individual manual experiments. Automation also reduces training requirements and helps retain knowledge as labor-intensive protocols are pre-programmed into robots. Overall, the increased throughput and efficiency of automation allows each researcher to achieve more using existing resources.
Potential Drawbacks of Automation
While lab automation delivers tremendous advantages, there are a few potential drawbacks to consider as well. High initial equipment costs for robotic platforms, liquid handlers and associated software/infrastructure present a barrier that favors larger well-funded research organizations. Some complex multi-step protocols involving specialized manipulations may still require human guidance that limits full automation. System malfunctions could potentially disrupt experimental plans if backups and redundancies are not properly implemented. Reduced human involvement may decrease situational awareness and troubleshooting abilities in some cases. Lastly, not all assays or analysis techniques have yet been adapted for robotic applications. But these limitations are progressively addressed with each new generation of more capable and affordable automated solutions.
In the lab automation has profoundly revolutionized the way scientific research and industrial testing is performed by dramatically increasing output and efficiency, while improving reproducibility and reducing costs. As robotics and informatics continue advancing together, the scope of tasks amenable to full automation will only continue expanding to encompass more complex experimental workflows. Automation ensures scientific and industrial labs worldwide maintain a higher level of productivity, sustainability and data-driven insight into the future.
