Whirl-Pak B01422 Hydrated Speci-Sponge® Bags - 18 oz. (532 ml) - Box of 100

A pre-moistened Speci-Sponge is designed for environmental surface sampling, allowing users to collect microbiological samples from equipment, work areas, or food processing surfaces. It is commonly used in food safety, sanitation verification, and contamination monitoring programs.

The sponge is pre-hydrated with a neutralizing buffer (typically ~10 mL) that helps neutralize disinfectants such as chlorine, quaternary ammonium compounds, and iodine. This ensures accurate recovery of microorganisms without interference from residual sanitizers.

Because the sponge comes ready-to-use with a controlled amount of buffer, it eliminates variability caused by manual wetting. This results in more consistent sample collection and reproducible laboratory results, especially in regulated environments.

Yes, pre-moistened Speci-Sponges are typically gamma-irradiated and individually packaged to ensure sterility. This prevents external contamination during sampling and makes them suitable for critical microbiological and regulatory testing applications.

These sponges are widely used to detect bacteria such as Listeria, Salmonella, E. coli, and other coliforms on surfaces. They are suitable for routine monitoring in food production, pharmaceutical, and environmental testing environments.
