Whirl-Pak® Cellulose Sponge Bags are designed for environmental surface sampling of work areas, equipment, animal carcasses, and any other place where testing for Listeria, Salmonella, E.coli, coliforms and other food-borne pathogens, or anthrax is required. The special natural cellulose dry sponge is free of bactericides and has been tested to be non-inhibitory. Wearing a sterile glove when wiping with the sponge is recommended to help prevent contamination.
Use your own buffer. Perfect for use with homogenizer blenders.
