Plate
Excellent sintered plate! It is strong chemically and physically. This is easy to handle, much more useful than any ones ever known. This is really reusable for dozens of time.
Especially This is useful for identification of antibiotic agent by means of bioautography. Furthermore, this is applicable for several kinds of fungi by means of a chromatogram. Separation is also good. This can be used without cares for diffusion of Silicagel in Rl sub stances. This is also useful in radioautographical operations.
