Modular method and device for the evaluation of the ability of biocide to penetrate biofilm

摘要

A thickness modular device for use in the evaluation of the ability of a biocide to penetrate biofilms of varying thicknesses is disclosed. It comprises: (a) a petri dish including a horizontal base and a continuous sidewall mending vertically from the base; (b) a dish cover including a flat base with a top and underside for closing the dish; (c) an internal thickness module having a flat top and bottom surface and being positioned adjacent the horizontal base for producing depressions on a surface of a biofilm; and (d) a locking member for connecting in a locking relation the dish cover with the internal thickness module.
