ELECTRONIC PIPETTE WITH DISPLAY AND MANIPULATOR FOR CONTROLLING LIQUID SUCTION AND DISTRIBUTION Russian patent published in 2008 - IPC B01L3/02 G06F3/33 

FIELD: physics.

SUBSTANCE: in an electronic pipette there is provision for controlling suction and distribution of liquids. The electronic pipette contains a computing device. The computing device consists of a control module and a main communication interface. The control module determines the operation carried out in the pipette. The main communication interface transmits electrical signal to the pipette, which determine the operation to be carried out in the pipette. The pipette consists of a sample pipe, piston unit, piston driving mechanism, second communication interface and a microprocessor. The piston unit is fixed to the sample pipe and has a piston plunger, which is inserted into the sample pipe. The piston driving mechanism has an actuating shaft, whose surface is in contact with the piston unit. The piston driving mechanism moves the piston plunger of the piston unit in the sample pipe, in a way that enables regulation of liquid in the sample pipe. The second communication interface receives electrical signals from the computing device. The microprocessor controls the piston driving mechanism and executes operations determined by the electrical signals.

EFFECT: simplification of choosing operational parameters; cutting time for changing settings in the device and provision for controlling using one hand.
