A dental centrifugal casting apparatus includes a crucible for receiving a dental casting material, a crucible holding unit for holding the crucible, a heating furnace such as a high-frequency induction heating furnace for heating and melting the dental casting material in the crucible, a crucible forward and backward rotary driving unit for driving the crucible holding unit forward and backward so as to insert the crucible into the heating furnace to heat and melt the material in the crucible and remove the crucible from the furnace, and for rotationally driving the crucible holding unit so as to inject the melted material into a mold at a predetermined position, a bucket for holding the mold in which the molten material is injected by the forward and backward motion and the rotation of the crucible performed by the crucible forward and backward rotary driving unit, and a centrifuge unit for rotating a rotary arm swingably mounting the bucket on its end portion at high speed immediately after the material is injected to apply a centrifugal force to the mold and molten material, thereby performing casting.

An assembly comprises a disc having an annular array of a number of reaction tubes formed adjacent to the periphery thereof. Each reaction tube is U-shaped and has its one end formed as an open-ended reaction chamber and its other end functioning as an air supply port. The link portion between the reaction chamber and the port is made transparent, forming a flow cell which permits the transmission of light which is used for the purpose of analytical determination. The assembly permits treatment with a reagent of a sample for reaction as well as a photometry for colorimetric analysis of the sample solution obtained by the reaction treatment of the sample.
