    摘要: The interseparating of desacetyl-cephalosporin C, desacetoxy-cephalosporin C and cephalosporin C can be accomplished by adsorbing these available cephalosporins on activated carbon and effecting a fractional elution thereof with water containing 0 to 20 percent (V/V) of an organic solvent or solvents.

    摘要: A cleaning tool for an optical connector includes a cylindrical cleaner and a holding member for holding a proximal portion of the cleaner. The cleaner has a main body with a ferrule insertion hole extending from a ferrule insertion port at its distal end face toward the proximal end of the cleaner. The ferrule insertion hole has an inner diameter substantially the same as an outer diameter of a ferrule. The ferrule insertion hole is surrounded by a rough surface so as to clean an outer surface of the ferrule which is to be inserted.
