3M™ Aqueous Sponge is specifically engineered for microbial surface sampling without biocide interference. Pre-hydrated with Neutralizing Buffer, it maintains organism viability for 48 hours under refrigeration for Salmonella and E. coli, and 72 hours for Listeria. Superior sample collection drives superior laboratory results. Pre-moistened sponges arrive ready-to-use with double-laminate bag and gloves for consistent, reliable outcomes every application. Both sponge and sample bag undergo gamma sterilization to preserve organism integrity and ensure extended shelf life. Integral to HACCP food safety management protocols globally, 3M sampling solutions identify and locate potential hazards throughout the supply chain.

Frequently Asked Questions

Why is biocide-free composition important for sampling?

Biocide-free formulation prevents interference with microorganism viability assessment, ensuring accurate detection and quantification of live pathogens like Salmonella, E. coli, and Listeria.

How long can samples remain viable during transport and storage?

Pre-hydrated sponges maintain Salmonella and E. coli viability for 48 hours under refrigeration, and Listeria viability for 72 hours, providing sufficient time for transport to analytical laboratories.

What is the purpose of the Neutralizing Buffer pre-hydration?

Pre-hydration with Neutralizing Buffer maintains optimal pH and osmotic conditions, maximizing organism survival during sample collection and storage.

Are these sponges compatible with HACCP food safety programs?

Yes. 3M sampling products are essential components of HACCP (Hazard Analysis Critical Control Point) protocols, enabling identification and location of potential food safety hazards throughout the supply chain.

Why is gamma sterilization used?

Gamma sterilization decontaminates both the sponge and sample bag while preserving microorganism detection capability and extending shelf life stability.
