Tryptic Soy Agar (TSA) with Lecithin and Tween® 80 is a widely used environmental monitoring medium designed for detecting, cultivating, and enumerating microorganisms recovered from surfaces. This formulation neutralizes a broad range of disinfectants—including quaternary ammonium compounds, phenolics, and alcohol-based sanitizers—making it ideal for validating cleaning effectiveness in controlled and regulated environments.

The optically clear polystyrene plates support distortion-free colony visualization, while the deep-fill format ensures robust microbial recovery even from stressed or low-level contamination events. Packaged in breathable sleeves of 10, these plates minimize condensation and maintain media integrity during storage.

TSA with Lecithin and Tween® 80 is routinely used in cleanrooms, compounding pharmacies, cosmetic manufacturing facilities, and quality assurance programs requiring verified aseptic practices.

Key Features
• Neutralizes disinfectants to support microbial recovery
• Deep-fill design improves organism detection and handling
• Optically clear for distortion-free visualization
• Heavy-duty plate construction reduces breakage
• Raised stacking rings prevent plate slippage
• Breathable packaging limits moisture and condensation

Applications
• Environmental monitoring
• Cleanroom sanitation verification
• Cosmetic and pharmaceutical manufacturing
• Hospital and sterile compounding (USP <797>/<800>)
• HACCP & quality control programs

How It Works
