In scientific laboratories, robotic liquid handling systems have revolutionized tasks such as DNA sequencing, automated drug discovery, and high-throughput screening.

In recent years, there has been a significant increase in the variety of robotic liquid handling systems available for labs. Market analysis predicts that the automated liquid handling solutions market will experience a growth of over 7% in the coming years, reaching a value of $4.65 billion by 2025.

The rising popularity of these systems can be attributed to the advantages they offer over manual liquid workflows. Automated liquid handling systems provide increased accuracy, speed, and throughput, making them highly desirable for tasks such as screening, sequencing, bioassays, sample preparation, and liquid weighing. When choosing the right liquid handling robot for a particular application, careful evaluation of each automated solution based on precise needs is essential.

What are Robotic Liquid Handling Systems?

Robotic liquid handling systems are advanced laboratory instruments that automate the precise and accurate transfer of liquids in a controlled and efficient manner. These systems utilize robotic arms, liquid handling modules, and associated software to perform tasks such as sample preparation, recent dispensing, plate replication, serial dilutions, and other liquid handling operations in laboratories.

It is used in various fields of life sciences, including genomics, proteomics, drug discovery, clinical diagnostics, and biotechnology research. They are designed to handle a wide range of liquid volumes, from microliters to milliliters, and offer high throughput capabilities, reducing human error and increasing the reproducibility and precision of experiments.

These systems typically consist of robotic arms that can move in multiple axes, liquid handling modules such as pipetting and dispensing units, plate handlers for transferring labware, and intuitive software for programming and controlling the system. They may also be integrated with additional devices such as plate readers, centrifuges, and incubators to create fully automated workflows.

There are several benefits, including increased productivity, improved accuracy, reduced sample contamination, and enhanced reproducibility. Modern laboratories rely on these highly adaptable tools that can be programmed to perform complex protocols with high precision, making them invaluable for handling liquids in a reliable and efficient manner.

A typical architecture for a robotic liquid handling system includes several key components:

  • Robotic Arm

This is the physical arm of the robot that is responsible for moving and manipulating various tools such as pipettes, syringes, and plates. The robotic arm is usually controlled by motors and is capable of precise and accurate movements.

  • Liquid Handling Tools

These are the tools that the robotic arm uses to perform liquid handling tasks. These tools are designed to aspirate, dispense, and transfer precise volumes of liquid with high accuracy and repeatability.

  • Deck or Workstation

This platform performs liquid handling tasks. It typically includes a flat surface with designated locations for different types of labware, such as microplates, tubes, and reservoirs. The deck or workstation may also include additional components, such as a barcode scanner, a temperature control module, or a shaker, depending on the specific application requirements.

  • Control Software

The software controls the system and offers a user interface to program liquid handling tasks, manage labware, and control the robotic arm. The software may also include features for data management, protocol customization, and integration with other lab instruments or systems.

  • Sensors

In this system, we use sensors to provide feedback and information about the status of the system. For example, the sensors detect the presence or absence of labware, verify liquid level, or monitor temperature and humidity. We use this information for process control, error detection, and system monitoring.

  • Communication Interfaces

Robotic liquid handling systems may have communication interfaces, such as Ethernet or USB, to enable connectivity with other lab instruments, devices, or systems. This allows for data exchange, integration with other lab workflows, and remote control and monitoring.

  • Power Supply

A robotic liquid handling system requires a power supply to provide power to the robotic arm, liquid handling tools, and other components. The system may integrate the power supply or an external provider can provide it.

  • Safety Features

Safety features are important in a robotic liquid handling system to ensure safe operation in the laboratory environment. These may include features such as collision detection, emergency stop buttons, and user authentication to prevent unauthorized access.
