Abstract
A flow unit especially useful for closed-channel Ferrographic analysis comprises a glass substrate, a plastic platen, and an elastomeric gasket sheet disposed between them. Holes in the gasket sheet form flow chambers. Opposite free ends of the gasket sheet extend beyond the edges of the substrate and of the platen so as to allow pulling the ends in opposite directions parallel to the surface of the substrate and thereby shearing the bond between the substrate and the gasket.
