Full-automatic gram-acid-fast double dyeing machine type A is a new generation of full-automatic bacteria and tuberculosis double dyeing machine independently developed by Zhengzhou Zhongpu, which fully owns independent intellectual property rights. It can provide two kinds of dyeing methods of bacteria and tuberculosis smears in a one-stop way to meet the double-high requirements of bacterial gram-acid-fast dyeing and tuberculosis acid-fast dyeing. It not only uses high-definition drop dyeing to prevent cross-contamination between samples, It also provides the precise requirements for the whole process of thermal dyeing and Gram dyeing time necessary for Zinni‘s acid-resistant dyeing. The equipment provides an automatic drying module, which not only ensures the preheating of the coating before dyeing, but also ensures the drying of the coating after dyeing. It has the technical characteristics of good biological safety, simple operation, one machine for two purposes, and particularly good dyeing effect.
