Product Overview

The Gram Stain Kit is a complete, high-quality reagent set designed for the differential staining of bacteria in microbiology, clinical diagnostics, and educational settings. This classical four-step method distinguishes between Gram-positive and Gram-negative bacteria based on the structural differences in their cell walls—an essential first step in bacterial identification, classification, and infection control.

This kit includes all necessary components for performing the Gram staining procedure with accuracy and consistency:

• Crystal Violet – the primary stain that binds to peptidoglycan in Gram-positive cells
• Gram’s Iodine – a mordant that forms a dye-iodine complex for retention in Gram-positive bacteria
• Decolorizer (Acetone/Alcohol) – removes stain from Gram-negative organisms
• Safranin – the counterstain that colors Gram-negative bacteria pink/red for easy differentiation

Whether used in clinical laboratories, research, industrial microbiology, or academic environments, the Gram Stain Kit delivers clear, vivid results that are easily visualized under a light microscope.

Key Features:

• Complete 4-step reagent system for Gram staining
• Clearly differentiates Gram-positive (purple) and Gram-negative (pink/red) bacteria
• Provides high-contrast, reproducible staining ideal for microscopic analysis
• Suitable for clinical diagnostics, microbiology labs, research, and teaching
• Packaged for convenience with pre-measured reagents for consistent results
• Available in multiple volumes to suit high-volume or instructional use

The Gram Stain Kit is an essential tool in any microbiology workflow, offering the clarity, reliability, and convenience needed for routine bacterial classification and microscopic examination.
