Sample identification/sorting apparatus and sample identification/sorting method

摘要

A sample identification/sorting apparatus includes a sample storage portion that stores samples dispersed in a liquid, a flow cell having a flow path through which the liquid flows, and a sorting nozzle that has a flow path communicating with the flow path of the flow cell and dispenses a sorting solution including the sample, which is a target sample, to a culture plate. A difference between a flow direction of the liquid at an outlet of the sample storage portion and a flow direction of the liquid at a leading end of the sorting nozzle is less than 90 degrees.

1. A sample identification/sorting apparatus that irradiates light onto a sample, which is a measurement target dispersed in a liquid flowing through a flow path, to measure optical information of the sample, determine whether the sample needs to be sorted on the basis of the optical information, and sort out a target sample, which is a sorting target, to a collection container on the basis of a determination result, comprising:
a sample storage portion storing the sample dispersed in the liquid; a flow ell including a first flow path through which the liquid flows and an optical information measuring unit which measures the optical information of the sample; a sorting nozzle including a second flow path which communicates with the first flow path of the flow cell and dispenses a sorting solution containing the target sample therein to the collection container; a sealing liquid introduction portion which supplies sheath liquid to the first flow path of the flow cell such that the sheath liquid surrounds the liquid in a tubular manner; and an introduction nozzle including a third flow path which introduces the liquid from the sample storage portion to the first flow path of the flow cell, wherein the second flow path has one exit without branching, wherein a difference between a flow direction of the liquid at an outlet of the sample storage portion and a flow direction of the liquid at a leading end of the sorting nozzle is less than 90 degrees, and wherein the liquid that is surrounded by the sheath liquid in the first and second flow paths from the flow cell to the sorting nozzle flows along a straight line within a cylindrical space.
