Abstract:
1. A microorganism counting cell, comprising: a bottomed cylindrical vessel that includes an upper surface opening; and a cylindrical retaining body disposed vertically on a bottom surface in the vessel for receiving a collecting element provided on a lower end portion of a rod-shaped microorganism collecting tool inserted therein, the retaining body disposed such that a radially exterior side surface of the retaining body is spaced from a radially interior side surface of the cylindrical vessel, a space that is formed in a shape of substantially circular ring between an inner peripheral surface of the vessel and an outer peripheral surface of the retaining body, and in which a liquid for eluting a microorganism is filled, and a liquid filled in the space formed between the radially exterior side surface of the retaining body and the radially interior side surface of the cylindrical vessel, and wherein the retaining body is provided with a plurality of first elution protrusions of a longwall shape formed in an axial direction of the retaining body at predetermined intervals around a radially interior side surface of the retaining body, and elution grooves, each formed to cut through a side surface of the retaining body from the inside to the outside between adjoining two of the plurality of first elution protrusions.
