The WHIRL-PAK® “Speci-Sponge” bags contain a 1 'A" x 3" sterile, non-inhibitory sponge for surface sampling to test for foodborne pathogens. Add DE neutraliz¬ ing broth to moisten the sponge, or use the dry sponge when wiping a wet area. After collecting the sample, return sponge to the bag, and send to lab for testing. Growth media may also be added after collection if desired. The DE broth neutralizes sanitizers which may be present on the surface. In addition to an 18 oz. size bag, NASCO introduces a NEW 55 oz. Stomacher® “Speci-Sponge” bag. It is designed to be used in the Stomacher® blender for thorough mixing of the Scimple and media. This is now standard procedure for USDA research work to identify foodborne pathogens.

For a FREE sample of a “Speci-Sponge” bag and a copy of our 1995-96 Sampling Products Catalog, write Dept. WL508 or call toll free.

The innovative ReSeal™ system provides all

the features you’ve come to expect in a sanitary hose ! assembly; sanitary full-flow compression seal, CIP cleanable, safe

and in compliance with regulatory standards — including 3-A Standard 62-00 i for sanitary hose assemblies. Call today for a free information packet.
