Abstract
A device for testing an elastic membrane for permeability ot submicroscopic particles. The device has a first chamber to contain the particles in a fluid medium; a second chamber to contain a reagent for detecting the presence of any of the particles; suitable structure for mounting the membrane between the chambers in a fluid-tight manner so that the membrane separates the chambers; and a mechanism for applying stress to the membrane.
