Abstract
Abstract A microculture slide chamber for simultaneously growing a plurality of mono-layer cell cultures on a slide includes a matrix which defines a plurality of generally parallel holes extending therethrough so that a plurality of wells for containing the culture bearing fluid are provided when the matrix is in abutment with a slide. Surrounding each hole on one side of the matrix is a gasket that is integral with the matrix and serves to seal the fluid in each well. A pressure plate with mating holes overlies the opposite side of each matrix and spring clips hold the plate, matrix and slide in assembled relation. A cover for the microculture slide chamber is provided.
