Abstract
A membrane perfusion apparatus and method for determining the effective rase rates of soluble biologically active chemical agents from a surface. A test cell houses a porous membrane so as to expose one surface of the membrane to a fluid containing at least one organism potentially reactive with a chemical agent of interest being perfused through the membrane at predetermined rates. In the context of antifoulant chemical agents, the invention permits the determination of the minimum effective release rates for biocides.
