Benz Microscope BZ5014 Negative Stain Kit


Product description

A negative stain colors the background of a specimen for bright field microscopy. Typically, it's performed using a black ink fluid such as nigrosin. The specimen, such as a wet bacterial culture spread on a glass slide, is mixed with the negative stain and allowed to dry. When viewed with the microscope the bacterial cells, and perhaps their spores, appear light, and thus visible, against the dark surrounding background. This differs from a positive stain in which the actual specimen is stained, or a direct stain in which the specimen itself is stained. Kit includes 1 - 30 ml bottle of the following solutions and SDS for each: Formalin-Nigrosin Solution Hydrochloric Acid 1% Congo Red 1% Aqueous Solution
