Abstract

PURPOSE:To capture microorganisms, etc., with good reproducibility and to maintain the cleanliness of a specimen water fixing cell by sliding a syringe in the fixing cell, sucking the specimen water and fixing the same. CONSTITUTION:The specimen water fixing cell 15 into which part of the specimen water is introduced and fixed is connected to a housing body for housing the specimen water, and the syringe 16 is driven by a motor 17 and is slid in an arrow A direction in the cell 15 by which the specimen water is sucked into the cell 15 and is discharged to the outside of the cell 15. The specimen water sucked and fixed into the cell 15 is projected by an illuminating lamp 20, is enlarged by an enlarging means 12 and is projected on a monitor television via a TV camera 13. The amt. of the fixed specimen water is always constant as the volume of the cell 15 is definite and further the fixing amt. of the specimen water in the range projected on the monitor television can be definitely calculated. The outflow of the microorganisms by the flow of the specimen water generated in the stage of fixing is obviated and therefore, the quantitative observation of the microorganisms, etc., is made possible.
