Whirl-Pak® Hydrated Speci-Sponge® Bag
Environmental surface sampling can be faster and easier by using the Whirl-Pak® pre-moistened Speci-Sponge® bag. The sponge is ready to use and is hydrated with 10 ml of neutralizing buffer that will neutralize several surface sanitizers including quaternary ammonium compounds, phenolics, iodine preps, chlorine preps, mercurials, formaldehyde, and glutaraldehyde. To use, squeeze out excess buffer from the sponge - this can be done by squeezing the sponge from the outside with two hands or squeezing the sponge with a sterile gloved hand after opening the bag. Wipe the surface to be tested, return the sponge to the bag, close, and send to the lab for analysis.
The buffer has a 24 month shelf life from date of manufacture and each carton is marked with an expiration date; no refrigeration is necessary. The bags are packaged in a foil liner bag to prevent evaporation of the buffer. Buffer contains monopotassium phosphate, sodium thiosulfate, and aryl sulfonate complex.
