7.5% Sodium Chloride Broth

Selective Enrichment Culture Medium for Staphylococcus aureus

7.5% Sodium Chloride Broth is a high-salt microbiological culture medium designed for the selective enrichment of Staphylococcus aureus in laboratory testing. The elevated sodium chloride concentration inhibits many competing microorganisms while allowing salt-tolerant staphylococci to grow effectively.

This medium is widely used in food microbiology laboratories, quality control testing, research laboratories, and microbiological analysis of food products and environmental samples.

The product is supplied in powder form for convenient preparation, providing consistent performance and reliable microbiological results.
