Abstract
A processing method for a volatile liquid using a pipette includes a low-volatility liquid suction step of sucking a low-volatility liquid that is less volatile than the volatile liquid through the suction/ejection port, an air suction step of sucking air through the suction/ejection port after the low-volatility liquid suction step, and a volatile liquid suction step of sucking the volatile liquid through the suction/ejection port after the air suction step.
Claims6
A processing method for a volatile liquid using a pipette including a cylinder, a piston that slides in the cylinder, and a tip attached to a tip end of the cylinder, the tip including a suction/ejection port, the pipette performing suction and ejection of a liquid through the suction/ejection port of the tip in accordance with movement of the piston, the processing method comprising:
- a low-volatility liquid suction step of sucking a low-volatility liquid that is less volatile than the volatile liquid through the suction/ejection port;
- an air suction step of sucking air through the suction/ejection port after the low-volatility liquid suction step;
- and
- a volatile liquid suction step of sucking the volatile liquid through the suction/ejection port after the air suction step.
A liquid processing apparatus comprising:
- a pipette including a vertically positioned cylinder, a piston that slides in a vertical direction in the cylinder, and a tip, the tip being attached to a lower end of the cylinder in such a way that an suction/ejection port provided at a tip end of the tip faces downward, the pipette performing suction and ejection of a liquid through the suction/ejection port of the tip in accordance with movement of the piston;
- a driving mechanism that causes the pipette to operate;
- a volatile liquid container accommodating a volatile liquid;
- a low-volatility liquid container accommodating a low-volatility liquid that is less volatile than the volatile liquid;
- and
- a Control part that controls the driving mechanism,
- wherein the Control part is configured to control the driving mechanism in such a way that a low-volatility liquid suction operation of sucking a preset amount of the low-volatility liquid from the low-volatility liquid container, an air suction operation of sucking a preset amount of air through the suction/ejection port after the low-volatility liquid suction operation, and a volatile liquid suction operation of sucking a predetermined amount of the volatile liquid from the volatile liquid container after the air suction operation are performed in a course of sucking the volatile liquid by the pipette.
