Liquid handling robot

Liquid handling robot is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Liquid handling robot rather than just read about it. In short: A liquid handling robot is used to automate workflows in life science laboratories. It is a robot that dispenses a selected quantity of reagent, samples or other liquid to a designated container.

Reference excerpt

A liquid handling robot is used to automate workflows in life science laboratories. It is a robot that dispenses a selected quantity of reagent, samples or other liquid to a designated container.

Introduction Liquid handling plays a pivotal role in life science laboratories. The sample volumes are usually small, at the micro- or nanoliter level, and the number of transferred samples can be huge. Under these conditions, liquid handling by hand is tedious, time-consuming, and impractical. Consequently, there is a strong demand for automated liquid handling robots.

Types of liquid handling robots The simplest version simply dispenses an allotted volume of liquid from a motorized pipette or syringe; more complicated machines can also manipulate the position of the dispensers and containers (often a Cartesian coordinate robot, and/or integrate additional laboratory devices, such as centrifuges, microplate readers, heat sealers, heater/shakers, bar code readers, spectrophotometric devices, storage devices and incubators. More complex liquid handling workstations can perform multiple Laboratory Unit Operations such as sample transport, sample mixing, manipulation and incubation, as well as transporting vessels to/from other workstations. An alternative category of liquid handlers mimics the operations of humans, by performing liquid transfers as humans would do. These robots achieve the cartesian, 3-axis movements implemented in larger workstations, by means of an arm.

Modularity Liquid handling robots can be customized using different add-on modules such as centrifuges, PCR machines, colony pickers, shaking modules, heating modules and others. Some liquid handling robots utilize Acoustic Liquid Handling (also known as acoustic droplet ejection or ADE) which uses sound to move liquids without the traditional pipette or syringe.

Quality Control One of the challenges in using automated liquid handlers, or liquid handling robots, is in verifying the proper function of the device. Liquid handling operations, performed by these automated systems, can fail due to clogged pipette tips, failed solenoid valves, damaged labware, operator error and many other reasons. A variety of methods exist for performing quality control of liquid dispensing on automated platforms including gravimetric, fluorescent and colorimetric measurements. In addition to manual quality control methods, technologies have been developed which allow for the automated monitoring of quality control of liquid handling robots.

Worked examples

Example 1 — a first encounter with Liquid handling robot

Start with the simplest possible case. Write down what Liquid handling robot claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Liquid handling robot before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Liquid handling robot ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Liquid handling robot

In research: Liquid handling robot appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Liquid handling robot in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Liquid handling robot is common in secondary-school and first-year university syllabi. It links to neighbouring topics Laboratory robots, Robotic manipulation, so understanding it makes those chapters shorter.
In everyday life: Look for Liquid handling robot outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Liquid handling robot in simple terms?

A liquid handling robot is used to automate workflows in life science laboratories. It is a robot that dispenses a selected quantity of reagent, samples or other liquid to a designated container.

Why does Liquid handling robot matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Liquid handling robot?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
