Abstract
ULTRAFILTRATION can prove a most valuable method for the investigation of disperse systems, but, in his treatise on the subject, Dr. Duclaux leaves his readers in no doubt as to its inherent difficulties. In spite of these, however, considerable progress has been made in recent years, attributable largely to the more reproducible and uniform membranes—‘Gradocol’—now available, covering an adequate range of graded porosities for the requirements of research workers in bacteriology, pathology, biochemistry and analytical chemistry. Thus far, their application has been restricted mainly to studies on bacteria, viruses and enzymes, for which they were specially evolved. That they have potential value in much wider fields is clear from the numerous references cited.
