The invention belongs to an
alkali metal transfer technology, and particularly discloses a micro-pipetting device and method for precisely transferring
alkali metal elements. The device comprises an anaerobic protection cavity, an
alkali metal melting module and an alkali
metal pipetting module, the alkali
metal pipetting module comprises a propelling
piston rod, a pipettor packaging holder and a
metal capillary tube, a glass micropipettor is arranged in the pipettor packaging holder, the propelling
piston rod extends into the glass micropipettor, a metal capillary wire is fixedly connected to the
power output end of the propelling
piston rod, the end, not connected with the propelling
piston rod, of the metal capillary wire is inserted into the metal capillary tube, a first heating unit is arranged on the periphery of the metal capillary tube, and a first heat preservation unit is arranged on the periphery of the first heating unit. The method comprises the following steps: heating and melting alkali metal elements to be transferred; and absorbing the alkali metal element by adopting a pipettor, and performing trace pipetting on the alkali metal element. According to the invention, nano-
liter-scale trace alkali
metal transfer can be realized, and the applicability is high.
