Product Description
Chapman Stone Agar is a specialized microbiological medium designed for the selective isolation and differentiation of staphylococci, particularly Staphylococcus aureus. This high-quality agar, manufactured by Himedia, is widely used in clinical and research laboratories for its reliability in identifying pathogenic strains.
The medium contains a high concentration of sodium chloride (7.5%), which inhibits the growth of most bacteria except staphylococci. The addition of mannitol and phenol red allows for the differentiation of mannitol-fermenting staphylococci, which produce yellow colonies, from non-fermenters, which appear red or pink.
Whether you’re a student, researcher, or educator, Chapman Stone Agar is an essential tool for microbiology experiments. Its consistent performance and ease of preparation make it a preferred choice for labs across India.

Key Applications
Chapman Stone Agar is commonly used in:
- Clinical microbiology for staphylococcus identification
- Research labs studying bacterial pathogens
- Educational institutions for microbiology practicals
- Food and environmental testing for staphylococcal contamination
Preparation and Usage
To prepare Chapman Stone Agar, suspend 110 grams of the powder in 1 liter of distilled water. Heat to boiling to dissolve completely, then sterilize by autoclaving at 121°C for 15 minutes. Cool to 45-50°C and pour into sterile Petri dishes.
For best results, store the prepared medium at 2-8°C and use within the recommended shelf life. Always follow standard microbiological practices when handling and disposing of cultures.
