D/E Neutralizing Agar

Product Code: 7375

Intended Use
D/E Neutralizing Agar is specifically designed for the isolation of microorganisms from sanitized environmental surfaces. Its unique formulation enables effective neutralization of disinfectants, ensuring accurate microbial recovery.

Product Summary and Explanation

D/E Neutralizing Agar was expertly developed by Dey and Engley to neutralize a wide range of disinfectants and preservative antimicrobial agents. This versatile medium is capable of neutralizing quaternary ammonium compounds, phenolics, iodine, chlorine preparations, mercurials, formaldehyde, and glutaraldehyde. Unlike standard neutralizing formulations, such as Letheen media, Thioglycollate media, and Neutralizing Buffer, D/E Neutralizing Agar consistently achieves higher levels of residual antimicrobial neutralization.

The total neutralization of disinfectants is crucial to prevent false negative results in microbial testing. Residual disinfectant activity may lead to erroneous conclusions regarding microbial presence or growth. D/E Neutralizing Agar effectively mitigates the inhibitory effects of disinfectant carryover, providing clarity between true bactericidal action and mere bacteriostasis of disinfecting agents. This characteristic makes it an essential choice for disinfectant evaluations, environmental sampling through swab and contact plate methods, as well as testing of water-miscible cosmetics.

Key Features

• Specialized formulation for optimal neutralization of antimicrobial agents.
• Supports microbiological culture from sanitized surfaces.
• Ideal for evaluating disinfectant efficacy and microbial recovery.
