Abstract:
A dispensing apparatus, a liquid dispensing method, and a cell dispensing method which can dispense liquid with very high accuracy. A dispensing apparatus includes a glass pipette, a tubular elastic member, a rod-shaped member, and a piezoelectric element actuator. A portion of the tubular elastic member located adjacent to a first open end thereof covers a portion of the glass pipette located adjacent to an opening portion thereof. A portion of the tubular elastic member located adjacent to a second open end thereof covers at least a forward end portion of the rod-shaped member. When the piezoelectric element actuator pushes the rod-shaped member toward the opening portion of the glass pipette, the tubular elastic member deforms such that the volume of the internal space of the tubular elastic member decreases.
