描述

一般說明

Crystal violet (C.I. 42555) for microscopy Certistain^®, is a dry dye that can be used to produce a Crystal violet staining solution to differentiate Gram-positive and Gram-negative bacteria in samples of human origin. In the case of Gram-positive bacteria, the bacteria retain their dark blue / dark purple color even after the treatment with decolorizing solution. On the other side Gram-negative bacteria are stained red or pink with the counterstain. As CERTISTAIN^® dye it is chemically quality-certified according to highest standards and strict specifications.
