Types of Medical Pipette
Volumetric pipettes
Volumetric pipettes are used to measure a single, fixed volume of liquid. They are typically made of glass or plastic and have a graduation mark on the stem that indicates the volume. Volumetric pipettes are very accurate and are often used for quantitative analysis.
Graduated pipettes
Graduated pipettes are used to measure a variable volume of liquid. They have multiple graduation marks along the stem that allow for measuring different volumes. Graduated pipettes are less accurate than volumetric pipettes, but they are more versatile and can be used for a wider range of applications.
Serological pipettes
Serological pipettes are a type of graduated pipette that is commonly used in cell culture and microbiology. They are typically made of plastic and are disposable. Serological pipettes are less accurate than glass pipettes, but they are more convenient to use.
Transfer pipettes
Transfer pipettes are used to transfer small volumes of liquid, typically in the milliliter range. They are often used for adding reagents to test tubes or for dispensing solutions into cuvettes. Transfer pipettes are not as accurate as volumetric or graduated pipettes, but they are very inexpensive and easy to use.
Micropipettes
Micropipettes are used to measure and transfer very small volumes of liquid, typically in the microliter (µL) range. They are essential for a wide range of applications, including molecular biology, biochemistry, and genetics. Micropipettes are more expensive than other types of pipettes, but they are very accurate and precise.
Electronic pipettes
Electronic pipettes are a type of micropipette that uses an electronic motor to aspirate and dispense liquid. They are very accurate and precise and are often used for high-throughput applications. Electronic pipettes are more expensive than manual pipettes, but they are faster and easier to use.

● 96 well microplates, frequently used in microplate applications like ELISA, PCR, or cell culture, are compatible with multichannel pipettes of 8 or 12-channel variants.
● To aliquot, a reagent into several doses- a process known as multi-dispensing- electronic pipettes are employed.
● Serological pipettes are employed in conventional laboratory settings and applications involving cell and tissue culture.
● Use pipettes to accurately measure small volumes of liquid. Pipettes function as tiny straws that suck up a liquid into the vacuum of its internal holding space. If you wish to extract a very precise, yet small, volume of liquid, a pipette is the tool you'll likely use.
● Keep the pipette tip away from the bottom of the vessel. When you want to draw up a volume of liquid into the pipette, make sure you keep the tip of the pipette elevated away from the bottom. Otherwise, you might cause a seal to occur, which can create air bubbles.
● Draw up liquid with the reverse pipetting technique. This method is only possible with air displacement pipettes. They draw up the liquid and disperse with any air bubbles or other forms of aspiration and is especially effective for drawing up and dispersing foamy or viscous liquid samples.
● Release liquid with the reverse pipetting technique. Once you've drawn up the liquid, you'll need to depress the plunger to the first stop and then continue through to the second stop. This will ensure that all the liquid in the pipette tip is expelled.
Components of Medical Pipette
Plunger
It is used to aspirate and dispense the desired volume of liquids.
Ejector button
It causes the metal bar to descend, ejecting the pipette tip.
Volume adjustment knob
The volume of the sample to be transferred can be set by rotating the volume adjustment knob to increase and decrease the concentration. It cannot be rotated in a fixed-volume pipette.
Volume window
It displays the set volume, and the place values shown depend on pipette size.
Shaft
It is a tube-like structure filled with air in an air displacement pipette. When the piston is pressed, some air from the shaft is released, aiding in liquid aspiration. In contrast, releasing the piston aids in liquid dispensing while refilling the shaft with air.
Tip cone
It is the area where the pipette tip is attached.
Pipette tip
It is a piece of equipment made of polypropylene or plastic that has been molded into it and comes into contact with the liquid.
