Whenever a laboratory procedure requires the transfer of a liquid measured in microlitres, a suitable micropipette can provide the control needed for the task.
Modern micropipettes are available in many configurations, including fixed-volume, variable-volume, single-channel and multichannel models. Depending on the design and intended application, some models can also be sterilized by autoclaving. Accessories such as pipette tips, stands, racks and tip boxes further support efficient liquid handling.
Selecting the right micropipette, however, requires more than simply choosing a volume range. Users should understand the difference between accuracy and precision, appropriate pipetting technique, tip selection, calibration, maintenance, storage and cleaning.
This complete guide explains the fundamentals of micropipettes and provides practical information for laboratories, researchers, students, procurement teams and laboratory equipment buyers.
A micropipette is a laboratory instrument used to aspirate and dispense small volumes of liquid, generally measured in microlitres (µL).
One microlitre is equal to:
1 µL = 0.001 mL
A typical adjustable micropipette consists of:
The exact design varies between manufacturers and models.
Laboratory experiments often depend on accurate liquid volumes.
Micropipettes help laboratories:
The importance of a micropipette therefore extends beyond the instrument itself. Proper pipetting technique, appropriate tips, environmental conditions and regular calibration all contribute to reliable liquid handling.
The term microlitre is represented by the symbol µL.
Some common laboratory volumes include:
A micropipette should be selected according to the required working volume.
For example, a laboratory frequently working around 10 µL may select a suitable low-volume micropipette rather than using a 100–1000 µL model.
The general principle is to select an appropriate pipette range for the volume being transferred rather than relying on a single pipette for every application.
Micropipettes can be classified in several ways.
The most common classifications are:
The right choice depends on the application, laboratory workflow and required volume.
A fixed-volume micropipette is designed to dispense a specific volume.
Examples may include:
The main advantage of a fixed-volume design is simplicity when a laboratory repeatedly performs a procedure at the same volume.
For example, if a particular routine requires repeated transfer of 100 µL, a fixed 100 µL micropipette can be convenient.
A separate pipette may be required for each different fixed volume.
A laboratory using 20 µL, 100 µL and 500 µL routinely may therefore need three different fixed-volume pipettes.
A variable-volume micropipette allows the user to select a volume within the specified operating range.
Common ranges include:
The exact available ranges depend on the manufacturer and model.
Variable-volume pipettes are useful when laboratory procedures require different volumes within the same operating range.
For example, a 20–200 µL micropipette may be used for several procedures requiring volumes within its specified range.
| Feature | Fixed Volume | Variable Volume |
|---|---|---|
| Volume setting | Fixed | Adjustable |
| Flexibility | Lower | Higher |
| Repeated single-volume work | Very suitable | Suitable |
| Multiple volumes | Requires multiple pipettes | One model can cover its specified range |
| Application | Dedicated workflows | Multiple workflows |
| Selection | Based on required fixed volume | Based on required working range |
Neither type is universally better. The appropriate choice depends on the laboratory’s workflow.
A single-channel micropipette has one liquid-handling channel.
It is commonly used for:
Single-channel models provide flexibility when samples are handled individually.
They are often the standard choice for laboratories performing a wide variety of liquid-handling procedures.
A multichannel micropipette has multiple channels that can aspirate or dispense liquid simultaneously.
Common configurations include:
Multichannel micropipettes are particularly useful when working with microplates or multiple wells.
Multichannel pipettes are commonly used in research, biotechnology and other laboratories where many samples must be processed efficiently.
Manual micropipettes are operated by the user through a plunger mechanism.
The user generally:
Manual micropipettes are widely used because they are relatively simple to operate and do not require an electrical power source.
Electronic micropipettes use an electronic mechanism for liquid handling.
Depending on the model, they may offer features such as:
They can be useful in laboratories performing high-volume or repetitive pipetting tasks.
Understanding the parts of a micropipette helps users operate and maintain the instrument correctly.
The plunger is pressed by the user to control aspiration and dispensing.
Many manual micropipettes have a two-stage plunger mechanism.
The first stop is commonly used for aspiration and normal dispensing, while the second stop can help expel residual liquid from the tip.
The exact operation should always follow the manufacturer’s instructions.
The volume adjustment mechanism allows the user to select the desired volume on variable-volume models.
It should be adjusted carefully and within the specified range.
Operating outside the specified range can affect performance and may damage the mechanism.
The volume display shows the selected volume.
Users should always check the display before pipetting.
The tip ejector allows the user to remove a used disposable tip without touching it directly.
This is particularly useful for maintaining cleanliness and reducing contamination risk.
The shaft connects the main body to the tip cone.
It is the part that enters or approaches the pipette tip.
The tip cone is the connection point for the disposable pipette tip.
The tip should fit securely and appropriately.
The tip is the component that directly contacts the liquid.
Tips should be selected for compatibility with the micropipette and application.
Many manual micropipettes operate using an air-displacement principle.
In a simplified explanation, pressing and releasing the plunger changes the air volume inside the pipette. This creates pressure conditions that allow liquid to be aspirated into and expelled from the disposable tip.
The general sequence is:
Set the required volume using the adjustment mechanism.
Attach a suitable pipette tip securely.
Press the plunger to the appropriate stop.
Place the tip into the liquid and slowly release the plunger.
Move the pipette to the receiving vessel.
Press the plunger to dispense the liquid.
Remove the used tip using the tip ejector.
This is a simplified overview. Actual operating procedures should follow the manufacturer’s instructions and the requirements of the laboratory application.
Accuracy refers to how close the delivered volume is to the intended or nominal volume.
For example, if a pipette is set to a particular volume, accuracy relates to how closely the actual delivered volume corresponds to that target.
Accuracy is important when precise liquid volumes influence an experiment or test.
Precision refers to how consistently repeated measurements or deliveries agree with each other.
A pipette could potentially deliver repeated volumes that are close to one another but consistently different from the target.
Therefore:
Accuracy = closeness to the target
Precision = repeatability/consistency
Both are important characteristics of liquid-handling performance.
Consider three repeated measurements.
If the results are:
100.1 µL
100.0 µL
100.2 µL
they are close to one another and close to 100 µL.
This indicates good repeatability and good agreement with the target in this simplified example.
If the results are:
103.0 µL
103.1 µL
103.0 µL
they are consistent with each other but are not close to the 100 µL target.
This illustrates why accuracy and precision are different concepts.
Selecting the right volume range is one of the most important purchasing decisions.
Common LABOLIT-style ranges include:
0.5–10 µL
Useful for small-volume laboratory applications.
2–20 µL
Useful where slightly larger volumes are required.
5–50 µL
Suitable for many routine liquid-handling applications.
10–100 µL
Useful for a broad range of laboratory procedures.
20–200 µL
One of the common ranges for routine laboratory liquid handling.
100–1000 µL
Suitable for larger microlitre volumes.
The appropriate model depends on the actual volume required by the procedure.
Consider the following factors.
Determine the volume most frequently used.
Choose a model that covers the intended working volume.
Choose fixed volume when the same volume is repeatedly required. Choose variable volume when multiple volumes are needed.
Choose single-channel for individual samples and multichannel when simultaneous transfer is needed.
If sterilization is important, select a model specifically designed and documented for the required autoclaving procedure.
A comfortable grip and smooth operation are important for repeated use.
Consider the laboratory’s calibration and quality-control requirements.
Ensure suitable tips are available.
Consider warranty terms and supplier support.
An autoclavable micropipette is designed so that specified components can withstand an autoclaving process under the manufacturer’s stated conditions.
Autoclaving is a steam-based sterilization process commonly used in laboratories.
However, not every micropipette is fully autoclavable.
Therefore, users should distinguish between:
Always follow the manufacturer’s instructions regarding which parts can be autoclaved and under what conditions.
Laboratories working with biological materials may require sterilization procedures.
Autoclavability can help simplify laboratory workflows where compatible equipment must undergo sterilization.
However, repeated autoclaving can affect materials if the product is not designed for the process.
Therefore, never assume that a micropipette can be autoclaved simply because it is made from plastic or metal.
Calibration is an important component of quality assurance.
Calibration evaluates the performance of the pipette against an appropriate reference or measurement method.
Laboratories may establish calibration schedules based on:
Calibration should be performed using suitable equipment and procedures.
A micropipette can gradually experience changes in performance due to:
Regular verification and calibration can help identify performance changes before they significantly affect laboratory work.
ISO 8655 is an important international standard series relating to piston-operated volumetric apparatus, including requirements and test methods relevant to pipettes and other liquid-handling instruments.
When purchasing or evaluating a micropipette, laboratories should examine the manufacturer’s documentation and determine which specific standard, edition and requirements apply to the product.
Manufacturers should avoid making broad claims about compliance without appropriate supporting documentation.
One commonly used approach for evaluating pipette performance is the gravimetric method.
In simplified terms:
Professional calibration laboratories should use appropriate procedures, equipment and environmental controls.
Many factors can influence pipetting performance.
Liquid temperature and ambient temperature can affect measurement.
Different liquids have different physical properties.
Highly viscous liquids may behave differently from water.
Volatile liquids can require special pipetting techniques.
Poorly fitting or unsuitable tips can affect results.
Different users may obtain different results if technique is inconsistent.
Damaged seals or mechanical components can influence performance.
The pipette tip is an essential part of the liquid-handling system.
A tip should:
Depending on the application, laboratories may use standard tips, sterile tips, filtered tips or other specialized tip designs.
Even a high-quality micropipette may not perform properly if the tip is unsuitable.
Potential issues include:
Therefore, users should consider both the micropipette and the tip as part of the liquid-handling system.
Correct technique is essential.
A basic workflow includes:
Exact technique may vary depending on the liquid.
Always check the display before aspiration.
Never set the pipette beyond its specified range.
Use compatible tips.
Rapid movement can affect liquid handling.
The tip should be immersed appropriately for the pipette and liquid.
Maintain an appropriate orientation and technique.
For applications requiring fresh tips, use a new tip to reduce contamination risk.
Regular verification is important for critical applications.
Regular maintenance helps preserve performance.
Basic maintenance may include:
Always follow the specific manufacturer’s maintenance instructions.
Cleaning requirements depend on the type of contamination and the pipette design.
A basic process may include:
Do not use cleaning chemicals that are incompatible with the pipette materials.
Proper storage can help protect the instrument.
A pipette stand can be useful because it:
Avoid leaving a pipette in an unsuitable position for long periods, particularly when liquid may have entered internal components.
A laboratory with multiple pipettes should use an appropriate stand or rack.
Available options may include:
The stand should securely hold the pipette and be placed in a convenient laboratory location.

Require appropriate contamination-control procedures.
Users should follow application-specific protocols.
Contamination control is critical in many laboratory environments.
Good practices include:
For sensitive applications, sterile or filtered tips may be appropriate.
Using the same disposable tip for multiple samples can introduce cross-contamination.
Therefore, laboratories should establish tip-changing procedures according to the application.
For high-sensitivity applications, appropriate sterile or filtered tips can provide an additional layer of contamination control when used correctly.
Every new user should receive appropriate training.
Training can cover:
Good training improves consistency among users.
Laboratories may establish routine performance checks.
A quality-control program can include:
The frequency should be based on laboratory requirements and risk assessment.
Possible signs that service or inspection may be needed include:
A damaged or malfunctioning pipette should not be used for critical work until it has been appropriately inspected.
Micropipettes should be handled as laboratory instruments.
Important practices include:
The micropipette itself does not eliminate the hazards associated with the liquid being handled.
A micropipette is a laboratory instrument designed to aspirate and dispense small liquid volumes, typically measured in microlitres.
Common types include fixed-volume, variable-volume, single-channel, multichannel, manual and electronic micropipettes.
Fixed-volume pipettes are designed for one specified volume, while variable-volume pipettes allow adjustment within a defined range.
Examples include 0.5–10 µL, 2–20 µL, 5–50 µL, 10–100 µL, 20–200 µL and 100–1000 µL.
Only models or components specifically designed for autoclaving should be autoclaved, and users must follow the manufacturer’s specified procedure.
The appropriate interval depends on usage, laboratory requirements, risk and applicable quality systems.
Accuracy describes closeness to the target, while precision describes repeatability.
The tip forms the liquid-contact interface and must fit the pipette correctly.
No. Each pipette has a defined operating range. Laboratories may need several models for different volumes.
A multichannel pipette transfers liquid through multiple channels simultaneously and is useful for repetitive multi-well workflows.
Before purchasing, ask:
Laboratory liquid handling continues to evolve.
Future developments may increasingly involve:
Manual micropipettes, however, remain highly useful because they provide flexibility and direct user control.
Manufacturers and suppliers can expand their market through:
