ABSTRACT:
The present invention provides a serum separating device and an apparatus for use in serum separation which is capable of completely separating serum and clot during the separation of a blood sample into serum and clot by means of a centrifugal separation operation. The serum separating device in accordance with the present invention is provided with a cylindrical member, which fits to an opening of a blood collection tube and which has an inner diameter which is slightly smaller than an inner diameter of the opening, and a movable member, the movable member comprising: a member main portion which is inserted into the cylindrical member and which presses against inner walls of the cylindrical member, and an annular isolating member which fits to an outer circumferential portion of the member main portion; wherein: the movable member has a specific gravity between that of serum and that of clot; and the annular isolating member comprises at least one of a material possessing elasticity and liquid permeability, and a material possessing the quality of swelling in response to immersion in liquid.
