Quantitative polymerase chain reaction (qPCR) has become an indispensable tool in modern research. It allows scientists to precisely quantify DNA in real-time by tracking fluorescence signals from tagged DNA molecules1. This technique is pivotal in studying gene expression, detecting genetic variations, and identifying pathogens with high sensitivity, making it essential in genetics, oncology, and drug development, among other research areas2,3.
However, the numerous manual, low-volume liquid handling steps in qPCR workflows are time-consuming and prone to errors, creating significant bottlenecks in workflows. Here, we uncover the true cost of manual qPCR workflows and explore how qPCR automation can save you time and money, making it a worthwhile investment for any lab that regularly performs qPCR.
Lab personnel often assume that the initial equipment purchase, such as a PCR machine, is the most significant expense in setting up a new workflow. However, this overlooks the substantial costs associated with running workflows manually, which can be categorized into three main areas: time, labor, and errors.
Manual qPCR workflows are highly time-consuming, mostly owing to the high number of pipetting steps, as scientists can only process one sample at a time. This limits throughput and prevents scientists from being able to scale workflows in line with the ever-changing demands of the project, delaying research progress.
Another important consideration when quantifying the true cost of manual qPCR workflows is the cost of labor. Often, repetitive pipetting tasks are performed by highly trained scientists such as postdoctoral research associates in academia or senior scientists in industry. Employing highly skilled professionals for low-skill activities is an inefficient use of resources and, put simply, a waste of money.
In addition to the obvious costs of time and labor, the hidden costs of errors in manual pipetting tasks are often overlooked4. The repetitive nature of manual qPCR workflows and the small volumes involved make them prone to human error and cross-contamination. These errors can necessitate costly and time-consuming repeat experiments, wasting reagents and delaying project timelines.
The true costs of manual qPCR workflows are often far higher than anticipated. Fortunately, time, labor, and error costs can all be substantially reduced through qPCR automation with tools like the I.DOT Liquid Handler (Fig. 1).

Automation enables the simultaneous processing of numerous qPCR samples, greatly accelerating research. Automated systems, such as robotic liquid handlers, can run multiple qPCR reactions in parallel, improving throughput compared to manual processing. This allows researchers to analyze more samples in less time, speeding up experimental timelines and data generation4.
qPCR automation frees researchers from repetitive, manual tasks, allowing them to focus on higher-value and, let’s face it, more interesting activities like data analysis and experimental design. This shift not only streamlines processes but also leads to significant savings in labor costs.
Automated liquid handling systems ensure precise and consistent reagent dispensing, minimizing pipetting inaccuracies and cross-contamination. This precision leads to fewer failed experiments and reduces the need for repeat runs, conserving valuable reagents and samples. By maintaining high-quality and reproducible results, qPCR automation minimizes waste and maximizes research efficiency5.
Beyond the significant time and cost savings, qPCR automation offers some notable additional benefits:

Understanding the benefits of qPCR automation is one thing, but ensuring the investment is worthwhile requires careful consideration to achieve a good long-term return on investment. To make sure the automated system purchase is suitable for your lab, consider the following factors:
Investing in qPCR automation transforms laboratory workflows by saving time and money while enhancing research outcomes. Automation increases sample throughput, reduces labor costs, and minimizes human errors, leading to more efficient and reliable experiments.
Additionally, automated systems improve data quality and consistency, reduce the risk of RSI, and ensure scalability to meet future research needs. By carefully selecting an appropriate automated pipetting system, labs can achieve substantial long-term returns on investment through improved productivity and cost-effectiveness.
