A liquid handling robot is a device that can automatically handle liquids in life science laboratories. It can perform various tasks such as dispensing, sampling, mixing, heating, shaking, centrifuging, and reading liquids. It can also integrate with other devices such as microplate readers, heaters, or barcode scanners. Liquid handling robots can improve the efficiency, accuracy, and reproducibility of laboratory workflows, as well as reduce human errors and contamination risks. In this article, we will introduce the types, benefits, and applications of liquid handling robots, as well as some of the latest trends and developments in this field.
Types of Liquid Handling Robot
There are different types of liquid handling robots, depending on the technology, design, and functionality. Some of the common types are:
- Motorized pipette or syringe: This type can dispense a fixed or variable volume of liquid from a pipette or syringe. The user can control the speed, pressure, and direction of the liquid transfer.
- Cartesian coordinate robot: This type can move the dispensers and containers in three dimensions (X, Y, and Z axes). This allows for more flexibility and precision in liquid handling, as well as integration with other devices.
- Anthropomorphic robot: This type mimics the movements of a human arm, by using joints, links, and motors. This type can perform liquid transfers as humans would do, with more natural and ergonomic motions.
- Acoustic liquid handler: This type uses sound waves to eject droplets of liquid from a source to a destination, without touching the liquid or the container. This type can handle very small volumes of liquid (nanoliters or picoliters) with high accuracy and speed, as well as reduce cross-contamination and waste.
The following table summarizes the main features and advantages of each type of liquid handling robot.
| Type | Features | Advantages |
|---|---|---|
| Motorized pipette or syringe | – Fixed or variable volume | – Simple and easy to use |
| – Speed, pressure, and direction control | – Low cost and maintenance | |
| Cartesian coordinate robot | – Three-dimensional movement | – Flexible and precise |
| – Integration with other devices | – Optimized and streamlined workflows | |
| Anthropomorphic robot | – Human-like movement | – Natural and ergonomic |
| – Joints, links, and motors | – Versatile and adaptable | |
| Acoustic liquid handler | – Sound wave ejection | – Fast and accurate |
| – No touch or contact | – No cross-contamination or waste |
Benefits of Liquid Handling Robot
Liquid handling robots can offer many benefits for life science laboratories, such as:
- Consistent results: Liquid handling robots can deliver precise and reproducible results, by eliminating human variability and errors. Liquid handling robots can also perform quality control checks, such as barcode scanning, volume verification, or sample tracking, to ensure the integrity and traceability of the samples.
- Optimized workflows: Liquid handling robot can increase the efficiency and productivity of laboratory workflows, by reducing the manual labor and time required for liquid handling. Liquid handling robots can also perform multiple tasks simultaneously or sequentially, as well as integrate with other devices or software, to create automated and streamlined workflows.
- Reduced costs: Liquid handling robots can reduce the costs associated with liquid handling, such as labor, consumables, reagents, or maintenance. Liquid-handling robots can also save space and energy, by using compact and modular designs.
Applications of Liquid Handling Robot
Liquid handling robots can be applied to various fields and applications in life science, such as:
- Drug discovery: A liquid handling robot can facilitate the processes of drug discovery, such as screening, synthesis, optimization, or characterization of drug candidates. Liquid handling robots can handle large numbers of samples, perform complex and diverse assays, and generate reliable and high-quality data.
- Genomics: Liquid handling robot can enable the analysis of genomic information, such as DNA sequencing, genotyping, or gene expression. Liquid handling robots can perform tasks such as DNA extraction, amplification, purification, or quantification, as well as handle sensitive and fragile samples.
- Proteomics: Liquid handling robot can support the study of proteins and their interactions, such as protein identification, quantification, or characterization. Liquid handling robots can perform tasks such as protein digestion, labeling, separation, or detection, as well as handle complex and heterogeneous samples.
- Cell biology: A liquid-handling robot can assist in the investigation of cellular functions and behaviors, such as cell culture, differentiation, or imaging. Liquid handling robots can perform tasks such as cell seeding, feeding, harvesting, or staining, as well as handle delicate and live cells.
Latest Trends and Developments in Liquid Handling Robot
Liquid handling robot is a dynamic and evolving field, with new trends and developments emerging constantly. Some of the current and future trends and developments are:
