In the fast-paced world of scientific research, precision, efficiency, and sustainability are crucial for success. While still widely used, traditional manual liquid handling methods come with significant limitations, including high variability, low throughput, and excessive waste1. The I.DOT Liquid Handler from DISPENDIX is an innovative, automated liquid handling solution that addresses these challenges head-on. With its advanced features and unparalleled accuracy, the I.DOT Liquid Handler is transforming laboratory workflows and empowering researchers to achieve more. This article explores the challenges of manual liquid handling and highlights the features that make the I.DOT Liquid Handler a standout solution for modern biological workflows.
Challenges in Traditional Handling
Manual liquid handling processes are plagued with challenges that put experimental success at risk. Even skilled researchers can make pipetting errors, and user variability complicates replication, making it challenging for scientists to collaborate and draw reliable conclusions2,3. Manual methods are inherently low throughput, especially when compared to more modern liquid handling techniques4,5. This means that research projects drag on, and researchers spend countless hours pipetting multi-well plates, putting themselves at risk of repetitive strain injury6.
Manual pipetting produces mountains of pipette tip waste, and dispensing errors squander costly reagents and necessitate repeat experiments and extensive troubleshooting (Fig. 1). This not only leads to even more plastic waste but also means that reagents need to be repurchased7,8. Moreover, manual dispensing methods mean these reagents must be used at an inefficient scale that is not optimized for sustainability or tight laboratory budgets.

The I.DOT Liquid Handler from DISPENDIX has emerged as an all-in-one solution to the challenges of traditional handling techniques by providing an automated, contactless, scalable liquid handling solution.
What Makes the I.DOT Unique?
Core Features
The I.DOT stands out among other dispensers because of its non-contact liquid handling technology and ultra-low volume dispensing, which makes it capable of dispensing volumes as low as 8 nL. Non-contact dispensing massively reduces the chances of contamination and the need for disposable plastics. Contamination from microbes or improperly dispensed reagents can jeopardize workflows and entire projects9. The I.DOT effectively eliminates these risks.
Advantages
The I.DOT boasts unrivaled precision and accuracy, with 1 μL dead volume, making it great for sensitive, high-cost techniques like next-generation sequencing (NGS). The I.DOT’s ability to dispense low volumes allows workflows to be scaled down, reducing costs by minimizing the use of excess reagents and enabling more efficient, waste-free experimental throughput. Furthermore, the I.DOT supports a range of liquid viscosities from methanol to 65% glycerol, which means it can support various applications, including genomics, proteomics, and drug discovery, at the nanolitre scale.
Real-World Applications of the I.DOT
High-Throughput Screening
The I.DOT allows high-throughput techniques to reach their full potential by dramatically increasing dispensing speed over traditional methods while improving accuracy. It allows researchers to perform other tasks while securing robust, reproducible data they can trust. The I.DOT can dispense 384 source liquids per run, meaning the only limitation for experimental design is the researcher’s imagination.
PCR Setup and NGS Library Preparation
PCR and NGS success hinge on the accurate dispensing of minute volumes. This is especially true in experiments that use precious patient samples, which are often low-volume. The I.DOT Liquid Handler simplifies tedious NGS library prep workflows and ensures researchers get the most out of their samples at a scale that supports resource and sample efficiency.
Assay Development and Optimization
Designing and setting up assays can be a complex and demanding task10. The last thing researchers need is to worry about whether their assay is failing because of variability in their own pipetting. The I.DOT reduces user variability, enabling researchers to focus on refining assay design and achieving optimization more quickly than with traditional methods.
Impact on Laboratory Efficiency and Sustainability
One area where the I.DOT Liquid Handler shines, especially for the environmentally-minded scientist, is its impact on reducing waste and contributing to more sustainable laboratory practices (Fig. 2). The I.DOT’s contactless dispensing and scalability mean that researchers need to purchase lower reagent volumes for their experiments and don’t need to worry about cross-contamination. The I.DOT uses significantly fewer pipette tips than manual pipetting and other automated technologies. This means less waste and more sustainable research.

Why Choose the I.DOT?
Simply put, the I.DOT enables scientists to complete workflows much faster than traditional methods, accelerating project completion and giving researchers a competitive edge. Furthermore, this speed advantage does not come at the expense of quality. On the contrary, the I.DOT Liquid Handler delivers exceptional accuracy, enabling researchers to achieve reliable results, drive innovation in their field, and streamline the development of groundbreaking technologies.
Conclusion
The I.DOT Non-Contact Dispenser is a game-changer for laboratories aiming to optimize efficiency, accuracy, and sustainability. By eliminating the inefficiencies and errors of manual pipetting, the I.DOT accelerates workflows, reduces waste, and enhances experimental reliability. For researchers looking to stay ahead in their fields, the I.DOT offers a powerful tool to unlock their full potential and drive the future of science with confidence and precision.
