(EN) VOLATILE LIQUID TREATMENT METHOD AND LIQUID TREATMENT APPARATUS
(JA) 揮発性液体の処理方法及び液体処理装置
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a method and an apparatus by which liquid spill from a pipette due to volatilization of a volatile liquid is suppressed.

SOLUTION: A volatile liquid treatment method with use of a pipette includes: a low volatile liquid suction step at which a low volatile liquid, which has volatility lower than that of a volatile liquid, is sucked from a suction/discharge port; an air suction step at which air is sucked from the suction/discharge port after the low volatile liquid suction step; and a volatile liquid suction step at which the volatile liquid is sucked from the suction/discharge port after the air suction step.
