A micro-pipette is a laboratory instrument used to suction and transfer small volumes of liquids and allow their handling in the different analytical techniques. The types of volumes that can be captured by this type of instrument vary according to the model; Among the best known are p20, p200 and p1000, they admit a maximum of 20, 200 and 1000μl.
The use of micro-pipettes should be highlighted, allowing the use of different liquids without having to wash said device, for this, disposable plastic tips are used, which are generally sterile. In addition, there are different types of tips; yellow ones for pipetting small volumes and blue ones for pipetting larger volumes.
There is a type of micro-pipettes that are manual, in which the volume to be aspirated is set by turning a button on the top that is connected to an analog volume confirmation system. And other automatic ones, where this newly named system is digital. In addition, there are simple micro-pipettes, which only accept one tip at a time, and other multi-channels, which allow the incorporation of multiple tips, absorbing the same volume in all of them.
