These pipettes trust in an air cushion among the piston and the liquid. once the piston is depressed, a vacuum is designed, drawing the liquid in to the disposable tip.
The major change would be that the disposable suggestion is actually a microsyringe (plastic), composed of a capillary plus a piston (movable internal aspect) which immediately displaces the liquid.
