A Note on The Use of Membrane Filters in Sterility Testing

Abstract

Filtration techniques have been applied advantageously in testing antibiotics and certain other medicaments, including oily solutions, for sterility, on the one hand by eliminating any residual bacteriostatic activity and on the other by eliminating interference through precipitation or the development of cloudiness. Membrane filters have been shown to be satisfactory for this purpose, and in some respects they are superior to asbestos pad filters.
