Abstract
A technology capable of preventing a sample from being retained is to be provided. Provided are a microchip that includes at least a sample inlet into which a sample is introduced, a sample flow path through which the sample introduced from the sample inlet flows, and a sorting flow path in which a target sample is sorted out from the sample, in which a first tube is inserted into and fixed to the sample inlet, and a sample sorting kit that includes at least the microchip.
Claims17
A microchip, comprising:
- a sample inlet into which a sample is introducible, wherein the sample inlet includes an abrupt expansion flow path;
- a sample flow path, wherein the sample introduced from the sample inlet is flowable in the sample flow path;
- a sorting flow path, wherein a target sample sorted out from the sample is flowable in the sorting flow path;
- and
- a first tube fixed to the sample inlet, wherein a volume of the abrupt expansion flow path is equal to or greater than πφ2L/4 m3, where o is an outer diameter of the first tube and L is a length of the first tube.
