FIELD: electronic equipment.
SUBSTANCE: invention is used for working with liquid. A manual pipette contains an energy collection device; an energy accumulator made with the possibility of storage of collected energy in the pipette; an electronic component connected to the energy accumulator and made with the possibility of use of the energy accumulator as a power supply source. In this case, the energy collection device is a system with a magnet passing through a coil connected to a pipette button and made with the possibility of energy collection, when pressing and releasing the button, or the energy collection device contains a heat-electrical generator, or the energy collection device contains piezoelectric material, while piezoelectric material is included in material of a pipette part.
EFFECT: provision of a possibility of addition of electronic functions to a mechanical pipette (with a mechanically actuated piston) without the need for transformation of the entire pipette into an electronic pipette, as well as provision of a possibility of reduction or elimination of dependence of electronic components on a pipette battery.
