There are many tasks performed in a laboratory and liquid handling is one of them. To do it precisely and accurately, you will need a micropipette, one of the most commonly used lab instruments. In this article, let’s figure out what a micropipette is, consider parts of a micropipette, and you will also learn about micropipette types, use, and Microlit micropipettes.
A micropipette is a piece of lab equipment that is used for the measurement & transfer of liquid samples. The micropipette pipette difference lies in the fact that a micropipette is a pipette used for working with small volumes of liquid (ranging from microliters µL to milliliters mL).
To sterilize micropipettes, autoclaving can be used. What is autoclaving? What is the definition of autoclaving? It is the process of laboratory equipment sterilizing where steam is used at high pressure. Learn more about autoclaving here.
It is recommended to check the calibration of your micropipette every month or every few months. Note that for calibrating a micropipette in accordance with ISO 8655 standards, there should be special ambient conditions. There are various factors that can affect the pipetting results. They include humidity, air pressure, temperature, etc.
What does a micropipette consist of? There are a few parts that ensure the proper functionality of a micropipette.
Main Micropipette Components
Plunger (for volume adjustment and liquid aspiration/dispensing)
Tip Ejector (pressed to remove the micropipette tips)
Volume Display (to show the liquid volume)
Tip Cone (to insert the tips)
Gripy (for supporting & holding the micropipette comfortably).
Micropipettes are classified depending on the following aspects:
Let’s consider the process of using an air displacement micropipette.
Depress the plunger using your thumb. As it is released, the liquid sample is drawn into a disposable tip. Press the plunger and the liquid will be dispensed.
Here is this process in more detail.

The plunger is depressed till the 1st stop Release the plunger |
To aspirate the liquid sample in the tip, press the plunger to the 1st stop. Immerse the tip vertically in the liquid. While the tip is immersed, release the plunger (slowly). The liquid sample will be aspirated into the tip. The liquid is filled in the tip as per the preset volume of your micropipette. |

Depress the plunger | For the liquid sample dispensing, the micropipette tip should be placed on the inner wall of the receiving vessel (at a steep angle). Press the plunger to the 1st stop (slowly) to dispense the liquid sample. If you need to empty the micropipette tip completely, the plunger should be pressed to the 2nd stop. As you remove the tip from the vessel, wipe it on the inner wall. |
Microlit liquid handling equipment is used by many professionals around the world. High precision, excellent build quality, durability, and ease of use are only a few benefits of Microlit products.
There are various models available when choosing Microlit micropipettes. Let’s consider a few popular options.
NERO Micropipettes are ergonomic and ensure high precision with the µAir technology. These are single-channel micropipettes with fixed and variable volume options.
BENEFITS
AQUA Electronic Micropipettes are excellent electronic volumetric pipettes. They are designed for precise & secure liquid measurement as well as transfer across a wide range of volumes (0.1 µL to 10000 µL). Featuring a detachable rechargeable battery, these portable micropipettes offer different pipetting modes. The Microlit AQUA ensures reliable experimental results while reducing the risk of repetitive strain injuries for users.
