1. A sampling device, comprising:
a sampling needle configured to be inserted into a sample container to collect a sample liquid in the sample container;
a needle-driving mechanism configured to change a position of the sampling needle;
a depth information acquirer configured to acquire insertion depth information which is a piece of information concerning an insertion depth of the sampling needle into the sample container;
a rinse storage tank having an opening on a top;
a needle-rinsing length setter configured to set a needle-rinsing length which is an insertion length of the sampling needle into the rinse storage tank, based on the insertion depth information; and
a controller configured to control the needle-driving mechanism so that a portion of the sampling needle extending from a tip of the sampling needle over the needle-rinsing length is inserted into the rinse storage tank to a depth based on the set needle-rinsing length, wherein the controller is configured to apply a different needle-rinsing length to the needle according to the insertion depth of the sampling needle into the sample container,
where the needle-rinsing length setter is configured to set the needle-rinsing length to be shorter as the insertion depth of the sampling needle into the sample container becomes smaller.
