    Abstract

    A relatively simple procedure has been developed which eliminates many of the difficulties frequently encountered in dissolving the thick layers of soluble plastics used as primary replicas in two-stage replica processes and as reinforcing or “backing” layers in the preparation of thin support membranes and direct replicas. The apparatus used in this procedure is a standard Soxhlet extractor which is equipped with a Z-shaped specimen carrier made of fine wire screen. The specimen carrier fits inside the extractor tube where it is held at a level slightly higher than the siphon tube by a wire or glass stand. The general features of this apparatus are illustrated in Fig. 1.
