Abstract

A simple and stable method by which samples in different forms can be acquired at once from a blood sample. A method for collecting microorganisms that comprises: introducing a blood sample 200 into a first storage part 100 of a container 1, said container 1 being provided with the first storage part 100 having a first flow path 103 and a second flow path 104 of different heights on the side face, a second storage part 101 and a third storage part 102; centrifuging the blood sample 200 at a first centrifugal force to separate into a bacterial solution 202 containing microorganisms and a solution 203 containing blood cells; centrifuging the blood sample 200 at a second centrifugal force greater than the first centrifugal force and moving the solution 203 through the first flow path 103 to the second storage part 101; centrifuging the second solution 203 at a third centrifugal force to separate into a bacterial solution 206 containing microorganisms and blood components 207 containing blood cells; and centrifuging the solution 203 at a fourth centrifugal force greater than the third centrifugal force and moving the bacterial solution 206 through the second flow path 104 to the third storage part 102.

A collection method comprising:

introducing a sample into a first storage part of a container including the first storage part having a first flow path and a second flow path of different heights on a side surface, a second storage part connected to the first storage part via the first flow path, and a third storage part connected to the first storage part via the second flow path;
centrifuging the sample introduced into the first storage part with a first centrifugal force to separate the sample into a first solution containing a first component and a second solution containing a second component;
centrifuging the sample stored in the first storage part with a second centrifugal force greater than the first centrifugal force and moving the first solution to the second storage part via the first flow path;
centrifuging the second solution stored in the first storage part with a third centrifugal force to separate the second solution into a third solution containing the first component and a fourth solution containing the second component;
and
centrifuging the second solution stored in the first storage part with a fourth centrifugal force greater than the third centrifugal force and moving the third solution to the third storage part via the second flow path.
