Guide and selection support
Liquid handlers are used in a wide range of laboratory applications where liquids must be transferred reliably and reproducibly. Typical areas of use include sample preparation, analytics, and automation in the field of liquid handling.
Important selection criteria for liquid handlers are the liquid volume, number of channels, type of fluid propulsion, as well as compatibility with existing laboratory instruments and automation solutions. Serviceability and precision also play a crucial role.
LabFinder offers a structured overview of liquid handlers and their variants, allowing for the quick identification of suitable systems to make laboratory processes more efficient and drive automation forward.
Applications and Benefits
Liquid handlers are instruments for precise and automated transfer of liquids in laboratories. They are used to replace or supplement manual pipetting operations, increase throughput, and reduce error sources caused by manual handling. Typical applications include sample and reagent preparation, dispensing into microtiter plates, and the standardization of recurring laboratory processes.
Through various technologies such as pipetting, pumping, or acoustic (echo) techniques, liquid handlers enable the handling of a wide range of volumes and liquid types.
Selection Criteria
The choice of a liquid handler depends primarily on the required liquid volume, the number of samples to be dispensed simultaneously (single or multichannel), compatibility with existing automation systems, and flexibility for different applications. Additional criteria include dosing precision and accuracy, ease of use, reproducibility, as well as maintenance requirements and reliability.
When comparing systems, it is advisable to consider the fluid transport technology and adaptability to different vessels and labware.
Variants and Measurement Principles
Liquid handlers are available in different configurations, from manual supportive devices to fully automated pipetting systems. The main technologies include classic piston pipetting principles, pump systems, and acoustic (echo) liquid transfer devices. Depending on the system type, volume ranges from nanoliters to milliliters are covered, in some cases with multichannel technology for parallel pipetting.
These variants provide flexibility for integration into laboratory automation processes and differ in speed, accuracy, and application fields.
Calibration and Maintenance
To ensure the accuracy of liquid handlers, regular calibration and maintenance are required. Intervals depend on the volume range, frequency of use, and manufacturer specifications. Maintenance includes cleaning, checking seals and pump elements, and software updates when necessary.
Routine care helps to prevent loss of precision and prolong the instrument lifespan.
Application Limits
Liquid handlers are not suitable for all liquids or volume ranges equally. Very viscous, foaming, or aggressive media can impair function. Special caution is also needed when handling extremely small volumes, as measurement errors can be more frequent. The instruments are usually designed for specific labware, so compatibility issues can arise.
Careful selection and adaptation to the respective laboratory requirements are therefore essential.

Frequently asked questions
How does a liquid handler work in principle?
A liquid handler transfers liquids automatically using mechanical actuators such as piston pipettes, pumps, or acoustic (echo) technology. The volume is precisely dosed and reproducibly transferred into defined vessels.
What types of liquid handlers are there?
There are manual, semi-automated, and fully automated liquid handlers. They differ technically, for example, through the fluid delivery principle such as piston pipetting, pump systems, or echo technology, as well as the number of channels and volume handling.
What criteria are important in selecting a liquid handler?
Essential factors include the dispensing volume, number of channels, delivery system, compatibility with existing laboratory equipment, ease of use, maintenance requirements, and dosing accuracy.
For which applications are liquid handlers particularly suitable?
They are especially beneficial for sample preparation, analytical applications, dispensing tasks in microtiter plates, and in general for automated liquid transfers in the laboratory to increase efficiency and reproducibility.
What are the limitations of liquid handlers in practice?
Limitations can arise with viscous or foaming liquids, very small volumes, media with special chemical properties, or insufficient compatibility with labware or automation systems.
