Liquid handling systems – find manufacturers and suppliers

Liquid handling systems are automated devices or systems for the precise dosing, transfer and mixing of liquids in laboratories and industry.

They are an essential part of modern laboratory technology, especially in biotechnology, pharmacy, chemistry and molecular biology, where precise and reproducible liquid quantities are essential for experiments and production processes.

Below you will find the functionality and types of liquid handling systems, their advantages and the challenges of using them:

How liquid handling systems work:

Liquid handling systems enable the accurate dispensing, distribution, transfer and storage of liquids.
The systems are designed to minimize errors that could result from manual pipetting methods while increasing efficiency and reproducibility.

Types of liquid handling systems:

1. Pipetting robots:
   These systems are capable of performing fully automated pipetting operations.
   They can dispense liquids with high precision and are often used in high-throughput processes (e.g. in drug discovery).
   Examples include platforms with 96- or 384-well plates that can handle large volumes of samples.
2. Liquid handling workstations:
   More complex systems that can automate multiple liquid processing steps, such as mixing, diluting, dispensing or distributing liquids.
   They often work with pipetting arms that can move to different positions.
3. Automatic dispensers and dilutors:
   These devices can automatically dispense liquids in specific quantities or prepare liquids in desired dilutions.
4. Microfluidic systems:
   These systems move liquids in a very small space, often in micro- or nanometer-sized channels.
   They are often used for molecular biological tests or biochemical analyses, as they work with extremely small volumes.
5. Liquid handling systems for viscous liquids:
   These systems are designed to handle viscous or difficult-to-handle liquids, such as gels or oils.
   They often use special pumps or valves to precisely dispense the liquid.

Areas of application for liquid handling systems:

1. Biotechnology and pharmaceutical research:
In drug discovery, automated pipetting robots and liquid handling systems are crucial for performing tests with thousands of samples in high-throughput screenings.
PCR (polymerase chain reaction), an important process in molecular biology, requires precise pipetting of small volumes of liquid, which is made possible by liquid handling systems.
In diagnostics, automated systems are used to dispense liquids onto test kits, dilute samples or mix reagents.

2. Chemistry and environmental sciences:
Liquid handling systems assist with titrations, dilutions and sample preparation in analytical laboratories. They help to ensure the accuracy and reproducibility of experiments.
In environmental science, they are used to analyze water samples, soil tests or chemical reactions.

3. Clinical diagnostics:
Liquid handling systems play a key role in sample preparation, analytics and diagnostic tests, such as ELISA and PCR.

4. Food and beverage industry:
Here, liquid handling systems help with quality control, for example when analyzing ingredients or performing microbiological tests.

5. Genome research:
These systems are essential for DNA/RNA extraction, genotyping, sequencing and other genomic applications.

Advantages of liquid handling systems:

• These systems are capable of dispensing extremely precise amounts of liquid, which is especially essential for biological and chemical experiments. Human error, as with manual pipetting, is minimized.
• Automated liquid handling systems can process large quantities of samples in a very short time, which significantly increases productivity in laboratories, especially in drug discovery or molecular biology tests.
• As these systems offer standardized and programmable workflows, they can ensure identical results in repeated experiments.
• Automated systems speed up laboratory processes considerably as they replace many manual steps and can be operated around the clock.
• By automating processes, errors are reduced, which ultimately saves material costs and minimizes the need for rework.

Challenges when using liquid handling systems:

• Calibration and maintenance: regular calibration and maintenance are required to ensure the accuracy and reliability of the systems.
• Liquid type limitations: Not all systems are suitable for handling viscous, volatile or aggressive chemicals, so specialized solutions are required for such applications.

Liquid handling systems are essential for precise and efficient work with liquids in laboratories and industry. They offer high accuracy and reproducibility, improve productivity and minimize errors.

They are irreplaceable in many areas of science and industry, particularly in biotechnology, pharmacy, chemistry and clinical diagnostics. They allow complex pipetting tasks to be carried out efficiently and reproducibly.

Below you will find an overview of the most important criteria that you should pay attention to when purchasing liquid handling systems:

When purchasing liquid handling systems, there are several important aspects to consider to ensure that the system is suitable for the intended application.

• Consider whether the system is suitable for your specific application, e.g. genomics, proteomics, cell culture or clinical diagnostics.
• Make sure that the system covers the required volume range, from microliters to milliliters, depending on the requirements of your experiments.
• Make sure the system offers high accuracy and precision to ensure reliable and repeatable results.
• Consider whether the system is scalable and whether it can be easily expanded if required, e.g. by adding more modules or channels.
• A flexible system that supports different liquid types, container formats (e.g. microplates, tubes) and applications can be useful for different workflows.
• Determine the level of automation required, e.g. manual, semi-automated or fully automated systems, based on your workload and throughput requirements.
• Check that the system is compatible with existing equipment and software solutions in your lab to ensure seamless integration.
• Make sure the system offers an intuitive user interface and ease of use to minimize training time and increase productivity.
• Find out about the system's maintenance requirements and whether the manufacturer offers reliable technical support and training.
• Consider the purchase and operating costs of the system, including consumables, maintenance and any upgrades.

By considering these points, you can ensure that the liquid handling system will meet your needs and provide efficient and reliable performance.
