micropipette principle

Micropipettes are essential tools in scientific research, allowing for precise and accurate measurement and transfer of small volumes of liquid. They are commonly used in fields such as biology, chemistry, and medicine, where the accuracy of measurements can have a significant impact on research outcomes. In this article, we will explore the principle of micropipettes and how they work.

The principle behind the function of a micropipette is based on air displacement. The micropipette consists of a piston, a calibrated volume, and a tip. When the piston is pushed down, it creates a vacuum that draws the liquid into the tip. The volume of the liquid drawn into the tip is determined by the calibrated volume of the micropipette. When the piston is released, the liquid is dispensed from the tip.

Micropipettes come in different sizes, with the most commonly used being the P10, P20, P200, and P1000 micropipettes. The numbers correspond to the maximum volume that can be dispensed by the micropipette, in microliters (µL).

To use a micropipette, the user must first set the desired volume on the micropipette using the volume adjustment dial. The micropipette is then used to aspirate the liquid by placing the tip into the liquid and depressing the plunger to the first stop. The tip should be fully submerged in the liquid to prevent air bubbles from being drawn into the tip. Once the liquid has been drawn into the tip, the micropipette is removed from the liquid, and the tip is wiped on the side of the container to remove any excess liquid.

To dispense the liquid, the tip is placed into the receiving vessel, and the plunger is depressed to the second stop. It is important to fully depress the plunger to ensure that all of the liquid is dispensed from the tip. Once the liquid has been dispensed, the tip is ejected by pressing the tip ejector button.

In conclusion, the principle of micropipettes is based on air displacement, and they are used to accurately measure and transfer small volumes of liquid. Understanding how to use a micropipette correctly is essential to ensure accurate results in scientific research.

Variable Volume semi autoclavable  Micropipette is a pipette that combines all the basics of a great device. A pipette is a lab device typically utilized in chemistry, biology as well as medicine to dispense a measured quantity of liquids like reagents, acids, alkalies, and media. Pipettes can be found in numerous layouts or designs for multiple functions with varying degrees of accuracy and precision, right from single piece glass pipettes to more complicated adjustable, flexible micro or electronic pipettes suitable for a wide range of experiments.

Features of a  Variable Volume semi autoclavable Micropipette:

  • high accuracy,
  • lightweight
  • long durability
