An object of the present invention is to improve the quality level discrimination accuracy of the grain G by a grain quality level discrimination device. The device includes an optical unitthat emits light to the grain G, receives reflected and/or transmitted light from the grain G by a photosensor, and obtains information for discrimination of the quality level of the grain G from the upper and lower surface side of the grain G, and a quality level discrimination unitthat discriminates the quality level of the grain G on the basis of the information. The information on the upper and lower surface sides can be acquired by one optical unit at the same time so that the divergence therebetween due to the displacement or variation of the attitude of the grain G can be avoided. The reference plate for the correction of the information is placed outside of the moving path of the grain G to prevent it from soiling or damaging. Thus the deterioration of information can be avoided. Further, a reference plate especially for the information to be obtained from the side surface of the grain G may be provided for enhancing the accuracy of the side surface information. Thus the quality level discrimination accuracy can be improved further.

A microorganism concentrator includes a water storage part that stores water sample therein and a filter that partitions the water storage part into a supply side and a drain side for the water sample. The microorganism concentrator concentrates microorganisms that are too large to pass through the filter on the supply side by moving the water sample on the supply side to the drain side of the water storage part. In the microorganism concentrator, the filter is arranged in such a way that no vertically downward force is applied to a surface of the filter on the supply side.
