Single-channel automatic pipette is one of the basic tools in laboratory work, especially in fields such as molecular biology, chemistry or medicine. It stands out for its precision, ease of use and the ability to perform repeatable and accurate liquid dosing. But how exactly does this tool work? In this article, we will present the mechanism of operation of a single-channel automatic pipette, its structure and practical applications that will make your work in the laboratory more effective.
Construction and operating principle of a single-channel automatic pipette
The single-channel automatic pipette consists of several key elements that together enable its operation. The most important parts include: the handle, the tip dispensing and ejection buttons, the spring mechanism, and the replaceable tips (so-called tips). The main function of this device is to precisely dispense a specific volume of liquid. The spring mechanism, which is the heart of the pipette, allows the liquid to be sucked into the tip when the piston is pressed and released. Then, when pressed again, the liquid is expelled from the tip, allowing for the precise transfer of specific volumes.
Thanks to the possibility of volume adjustment (usually in the range from 1 μl to 10 ml), the single-channel automatic pipette is extremely versatile. Laboratory workers value it for its ease of use and precision. However, it is important to select the appropriate pipette range for the volume of liquid that we want to dispense. Incorrect settings can lead to inaccuracy or even damage to the device mechanism.
Practical applications of single-channel automatic pipette
Single-channel automatic pipettes are used in many fields of science and industry. They are most often found in research, clinical and educational laboratories. Examples of applications include:
- PCR (polymerase chain reaction) related work – the pipette is used to precisely dispense reaction mixtures such as buffers, enzymes, and DNA/RNA samples.
- Biochemical analysis – dosing samples into microtiter plates or test tubes.
- Preparation of solutions and standards – thanks to the ability to precisely dose even the smallest volumes, the pipette enables the creation of precise working solutions.
- Routine laboratory activities – including transferring small volumes of liquid between different containers.
The key aspect of working with a single-channel automatic pipette is its regular maintenance and proper use. Remember to always use the right tips that fit the pipette model. It is also worth avoiding contact of liquid with the pipette mechanism, which could lead to its damage.

How to care for a single-channel automatic pipette?
In order for a single-channel automatic pipette to operate efficiently and precisely for a long time, it is necessary to clean and calibrate it regularly. Most manufacturers recommend calibrating it every few months or after several thousand dispensing cycles. Cleaning, however, should be done more often, especially after working with viscous, corrosive or biologically active substances.
Practical tips for maintaining your single-channel automatic pipette:
- After each use, remove the tip and wipe the handle with a damp cloth.
- Use special detergents or isopropyl alcohol to clean external surfaces.
- Avoid disassembling the mechanism yourself – this may cause permanent damage.
- Store the pipette upright on a stand to avoid accidental flooding of the mechanism.
Summary
The single-channel automatic pipette is an indispensable tool in every laboratory, enabling precise and repeatable dispensing of liquids. Thanks to its versatility, ease of use and availability in various volume ranges, it is used in a wide range of applications - from research to routine laboratory activities. The key to effective use of this device is not only knowledge of its operation, but also regular maintenance and proper calibration.
