Abstract:
A ceramic heat exchanger includes a heat exchange section that heat-exchanges between two fluids A and B flowing opposite directions to each other. The heat exchange section includes ceramic blocks stacked one on top of another with a seal therebetween. The ceramic blocks have a plurality of parallel lines of flow channels, each line defined by the flow channels through which the same fluid flows, any two adjacent lines being defined by the flow channels through which the different fluids A and B flow respectively. Both ends in the stacking direction of the stack are bound to join and integrate the ceramic blocks with tightening means including end plates and a tie rod. A thermal expansion absorber is disposed on an external surface of the end plates for absorbing thermal expansion in the axial direction of the tie rod.

Abstract:
A method for distinguishing erythrocytes in a biological specimen, includes preparing a sample liquid so as to cause damage to a cell membrane of yeast-like fungi without hemolyzing erythrocytes in a biological specimen and to stain the yeast-like fungi with a fluorescent dye; detecting a first information and a second information from a particle in the sample liquid, wherein the first information reflects a size of the particle and the second information reflects a degree of fluorescent staining of the particle; and distinguishing the erythrocytes from the yeast-like fungi based on the first information and second information detected. An apparatus, a reagent kit and a reagent for carrying out the method are also disclosed.
