Staining is a process in which the tissue sample is exposed to colored dye which penetrates specific cell components to make the component of interest more visible under the microscope. Slide stainer stain prepared slides of processed tissue to enhance the contrast within a specimen for microscopic study. The operator to be heat the slides loads it into the solution reservoir and depending on requirement it is stained once or twice then rinsed and dried. - Multiple sets of programs are available for editing (non-sequential editing can be performed, and dyeing steps and time can be programmed arbitrarily) . Multiple sets of programs are available for editing (non-sequential editing can be performed, anddyeing steps and time can be programmed arbitrarily) . Automatic drying temperature can be set. The temperature around the drying cylinder is uniform, and there is a water and gas overflow. Automatically control the flushing water level. When the dyed hanging blue enters the washing tank, the water is automatically filled in the washing tank. When the hanging blue leaves the washing tank, the water injection is automatically stopped, and the water in the tank is drained. The drip residence time is adjustable. The dripping time can be adjusted according to the sample volume and ambient temperature to ensure the purity of the reagent.
