迅速容易な2段レプリカ法 (Filmy Replica System) の改良

抄録

For plastic two-step replica method, methacrylate resin film is used for the first step instead of conventional acetyl cellulose film to avoid large swelling in disolving process.
Plastic three-step replica method is devised in which the first step is the application of wetted film of water-soluble and easily detachable plastics such a methocel, polyvinylalcohol, gelatine etc. on the specimen. As the second step, methacrylate resin film is used on the detached first film as in the above-mentioned improved two-step method. The third step is germanium shadowing and carbon evaporation on the second film.
By these processes, the time required for completion of replica is shortened: 30 minutes for the two-step and 40 minutes for the three-step method. These methods are well suited to routine work, for the processes are easy and sure. Judged from discriminable minute striation on ceramic alumina, resolution of these replicas is found as good as that of customary replica.
Details of preparation are briefly explained.
