LokTight™ Tryptic Soy Agar (TSA) with Lecithin and Tween® 80 Contact Plates, USP Grade

Also commonly referred to as Rodac™ plates, these standard contact plates feature the innovative LokTight™ locking lid that securely fastens to the base post-sampling, preventing contamination and ensuring secure transport to the laboratory. The friction lid design maintains secure placement before sampling to prevent pre-sampling contamination, while the molded grid on the plate bottom aids accurate microorganism counting for trend analysis and action level monitoring. The TSA base medium with lecithin and Tween® 80 provides general-purpose growth support for a wide variety of microorganisms while neutralizing quaternary ammonium compounds, phenolics, and other common disinfectants that could interfere with organism recovery. A Certificate of Analysis is available online for each lot, providing the quality documentation essential for GMP compliance and regulatory audits. Ideal for environmental monitoring in cleanroom settings, pharmaceutical manufacturing facilities, and any biologically controlled environment requiring accurate surface contamination assessment with documented quality assurance.
