Hardy Diagnostics Tryptic Soy Broth (TSB) with Lecithin and Tween® 80 is a broad-spectrum enrichment and neutralizing medium designed for the cultivation of microorganisms and recovery of contaminants from disinfected or sanitized environments.

This formulation combines TSB, a nutrient-rich base that supports a wide variety of bacterial and fungal species, with Lecithin and Tween® 80, which effectively neutralize surface disinfectants and cleaning agents. The result is a medium ideal for environmental monitoring, sterility testing, and validation of cleaning processes in controlled environments such as cleanrooms, pharmaceutical manufacturing facilities, and cosmetic production areas.

Packaged in sturdy polypropylene bottles with a 500 mL fill volume, these ready-to-use sterile broths eliminate preparation time and reduce contamination risk while providing consistent, reproducible growth results.

Features and Benefits:
• Supports cultivation of a wide range of microorganisms, including bacteria and fungi
• Neutralizes quaternary ammonium compounds, phenolics, and alcohol-based disinfectants
• Ready-to-use sterile format eliminates the need for in-house media preparation
• Durable polypropylene bottles resist breakage and provide clear visibility
• Ideal for aseptic processing, sterility validation, and microbial recovery studies
