The automated micropipette is usually remarkably specialised–in contrast to manually measuring the liquid to line as many as a graduation mark, as would be the custom in everyday pipettes, computerized micropipettes enable the scientist to set the quantity of liquid that needs to be transferred beforehand by way of a digital volumeter. All micropipettes work like an automatic syringe, but The 2 Main types–the air-displacement pipette plus the constructive-displacement pipette–differ dependant on the presence of the air cushion amongst the pipette piston and also the liquid sample.
