Embodiment Construction

[0039] Hereinafter, an embodiment of the volatile liquid processing method of the present invention and the liquid processing apparatus for executing the processing method will be described with reference to the drawings.

[0040] First, use figure 1 An embodiment of the liquid processing device will be described.

[0041] In the liquid processing apparatus of this embodiment, the plurality of pipettes 2 are held by the holder 10 in a state of being lined up. The pipette 2 includes a tube 4 arranged in the vertical direction, a piston 6 that slides in the vertical direction in the tube 4, and a suction head 8 attached to the lower end of the tube 4. The suction head 8 has a suction / discharge port at the front end, and the suction / discharge port is vertically downward.

[0042] Each pipette 2 sucks liquid and gas from the suction / discharge portion of the suction head 8 in accordance with the upward operation of the piston 4, and discharges liquid and gas from the suction / discharge p...

Abstract

Provided is a method for treating a volatile liquid using a pipette, the method comprising: a low volatile liquid suctioning step of suctioning a low volatile liquid, having a lower volatility than the volatile liquid, from a suctioning and discharge port; an air suctioning step of suctioning air from the suctioning and discharge port, after the low volatile liquid suctioning step; and a volatileliquid suctioning step of suctioning the volatile liquid from the suctioning and discharge port, after the air suctioning step.

Description

Technical field [0001] The present invention relates to a method for processing a volatile liquid using an air displacement type piston pipette, and a liquid processing device for executing the method. Background technique [0002] In physical and chemical experiments, in order to measure and dispense liquids, air displacement piston pipettes are widely used. The piston type pipette has a structure that allows air to flow in and out of the barrel by moving the piston up and down in the barrel. By adjusting the distance that the piston moves up and down, the liquid can be accurately measured in the tip installed at the tip of the barrel. . [0003] Electric-operated piston pipette devices are also sold by various companies, which can perform continuous suction and continuous discharge. As such automatic dispensing devices, there are Bravo from Agilent, NIMBUS from Affymetrix, epMotion from Eppendorf, Microlab from Hamilton, Biomak from Beckman Coulter, and the like. [0004] Becaus...
