Gram Stain Set, 250 ml - Case of 4

The Gram Stain Set is a comprehensive four-part diagnostic system designed for the primary differentiation of bacterial species into Gram-positive and Gram-negative groups. This professional-grade kit includes one 250 ml bottle each of Gram Crystal Violet, Gram Iodine, Gram Decolorizer, and Gram Safranin. To ensure the highest level of diagnostic reliability, all staining solutions are manufactured using powders certified by the Biological Stain Commission (BSC). This standardized set allows laboratory professionals and researchers to achieve high-contrast results, where Gram-positive organisms are clearly identified by a deep purple hue and Gram-negative organisms are visualized with a bright red or pink counterstain.

Key Features & Benefits
