A plastic micropipette is a laboratory liquid-handling instrument designed to aspirate and dispense relatively small volumes of liquid.
Depending on the model, a micropipette may be available as:
The term “plastic” generally refers to the use of engineered polymer materials in part of the pipette construction or in disposable tips. It does not necessarily mean that every internal component of the instrument is made entirely from plastic.
High-quality laboratory micropipettes may use materials such as:
The exact materials vary according to the manufacturer and model.
Plastic materials can provide several useful characteristics for laboratory equipment.
Engineering plastics can help reduce the overall weight of a pipette.
A lightweight instrument can be more comfortable during repetitive pipetting tasks.
Modern plastic components can be molded into ergonomic shapes that fit comfortably in the user’s hand.
Certain laboratory-grade polymers provide good resistance to a variety of commonly handled laboratory chemicals.
The actual compatibility depends on the specific polymer and chemical.
Smooth external surfaces can make routine cleaning easier.
Injection molding and other manufacturing methods allow manufacturers to produce complex ergonomic components with consistent dimensions.
Suitable engineered plastics can contribute to economical production while maintaining appropriate mechanical performance.
It is important to distinguish between a plastic micropipette and a simple disposable transfer pipette.
A micropipette is a precision liquid-handling instrument with a defined operating mechanism and volume setting.
For precise laboratory measurements, a calibrated micropipette with a compatible pipette tip is generally the more appropriate instrument.
Most manual micropipettes use a piston-based mechanism.
The basic operation involves:
The exact operating principle varies according to pipette design.
Understanding the parts of a micropipette helps users operate and maintain the instrument correctly.
The plunger is pressed by the user during aspiration and dispensing.
Variable-volume models use a mechanism that allows the user to select the desired volume.
The selected volume is shown through a numerical display.
The main body provides the ergonomic grip and houses the operating mechanism.
Many micropipettes have a tip-ejection mechanism that allows used tips to be removed without touching them.
The shaft connects the main pipette body with the tip cone.
The tip is attached to the tip cone.
The piston moves to create the displacement required for aspiration and dispensing.
These components help maintain the required air seal.
The disposable tip is the component that directly contacts the liquid.
Plastic micropipettes can be categorized in several ways.
A single-channel micropipette contains one tip cone and transfers liquid through one channel.
It is suitable for:
Single-channel pipettes are available in many volume ranges.
A variable-volume micropipette allows the user to select different volumes within a defined range.
For example:
20–200 µL
This means the instrument is designed to operate within its specified 20 to 200 µL range.
Other commonly encountered laboratory ranges include:
The actual available ranges depend on the product.
A fixed-volume micropipette is designed for a specific volume.
Examples may include:
Fixed-volume models can be useful when a laboratory repeatedly performs the same liquid transfer.
Multichannel micropipettes contain multiple channels and can transfer liquid into several wells simultaneously.
Common configurations include:
They are particularly useful for microplate-based applications.
Applications include:
Pipette tips are an important part of any micropipette system.
Disposable plastic tips are commonly manufactured from laboratory-grade polymers, frequently polypropylene.
Depending on the application, tips may be:
The tip must be compatible with the micropipette.
The pipette tip forms the liquid-contact interface between the instrument and the sample.
Poor-quality or incompatible tips can contribute to:
For critical laboratory applications, users should select appropriate tips from a reliable source.
Different micropipette ranges require different tip capacities.
Examples include:
Commonly used for very small liquid volumes.
Widely used with micropipettes operating around the 20–200 µL range.
Used with larger-volume micropipettes, often around the 100–1000 µL range.
Larger pipette systems may use specialized tips for millilitre-scale liquid handling.
Tip dimensions and compatibility vary by manufacturer, so users should always confirm specifications before purchase.
Plastic micropipettes offer several practical benefits.
A lightweight construction can make repetitive pipetting more comfortable.
Modern designs can provide a comfortable grip and easy plunger operation.
A compact design makes the instrument convenient for routine laboratory use.
Plastic components can support cost-effective manufacturing.
Plastic-bodied micropipettes can be used across many general laboratory applications.
Smooth polymer surfaces are generally convenient for routine cleaning.
Plastic micropipettes are available in many volume ranges and configurations.
A micropipette’s accuracy does not depend simply on whether it contains plastic.
Accuracy depends on many factors, including:
A well-designed and properly calibrated micropipette can provide reliable liquid handling.
Calibration is an important part of maintaining micropipette performance.
Calibration determines whether the instrument delivers the intended volume within the required acceptance criteria.
A common calibration approach is the gravimetric method.
In a simplified explanation:
Professional calibration should follow an appropriate documented method and applicable requirements.
A variable-volume 20–200 µL micropipette is a popular laboratory range.
Representative calibration points may include:
The purpose is to evaluate performance across the operating range.
A calibration report may include:
The exact test method and acceptance limits should be based on the applicable standard, manufacturer specification, and laboratory procedure.
Accuracy and precision are both important.
How close the delivered volume is to the target.
How closely repeated measurements agree.
For example, a pipette might produce:
99.9 µL
100.0 µL
100.1 µL
for a 100 µL target.
The measurements are close to each other, demonstrating good repeatability. Whether the result meets a formal accuracy specification depends on the applicable acceptance criteria.
Correct technique is essential.
Choose a pipette whose operating range is appropriate for the desired volume.
Adjust the volume setting carefully.
Do not force the adjustment mechanism beyond its designed range.
Fit a compatible pipette tip securely.
Use the appropriate plunger stop.
Place the tip correctly into the liquid and release the plunger smoothly.
Move the pipette to the receiving vessel without unnecessary movement.
Press the plunger smoothly and consistently.
Use the tip-ejection mechanism and dispose of the tip appropriately.
Even a high-quality micropipette can produce poor results if used incorrectly.
Common mistakes include:
Operator training is therefore an important part of accurate liquid handling.
Regular maintenance helps protect performance.
Wipe the pipette according to the manufacturer’s instructions.
Check for cracks, contamination, or damage.
The plunger should operate smoothly.
Where accessible, inspect seals and O-rings according to the service procedure.
Unexpected liquid leakage can indicate a problem with the tip, seal, piston, or other components.
Calibration intervals should be determined according to laboratory requirements, usage, manufacturer’s recommendations, and historical performance.
Some micropipettes or specific components may be designed for autoclaving, while others may not be.
Autoclaving involves high-temperature steam sterilization, and not every plastic material or pipette component is suitable for it.
Therefore:
Never assume that a plastic micropipette is fully autoclavable simply because it is made from laboratory-grade plastic.
Always follow the manufacturer’s instructions regarding:
Plastic materials differ significantly in their chemical resistance.
Some chemicals may cause:
When working with aggressive solvents or corrosive chemicals, consult the manufacturer’s chemical compatibility information.
Do not assume that all plastic materials have the same resistance.
Molecular biology laboratories rely heavily on micropipettes.
Typical applications include:
Small-volume accuracy is particularly important in molecular biology because reagent concentrations can influence reaction performance.
