The single-step and double step lilpet come with single and double piston strokes respectively. In a single step, the plunger is depressed till the FIRST stop only which is the lowest-most position for aspiration as well as dispensing the liquid. While in double step, to aspirate the liquid the plunger is depressed till the FIRST step only, and to dispense the plunger is depressed till the SECOND step to ensure that the last drop is dispensed. The double step lilpet facilitates the reverse pipetting and reduces the loss of liquid dispensed, thereby enhancing the accuracy of the pipette. These features allow the usage of the pipette for test kits.
