Make environmental surface sampling faster and easier with Whirl-Pak Polyurethane Surface Sampling Sponge Bags. Our durable high-density polyurethane sponge is ready to use and resists tearing and fraying.

Each sponge is packed in a sterile, sealed write-on bag with your option of a dry or hydrated sponge. Hydrated with 10 ml of HiCap™ Neutralizing Broth.

To use the sponge, tear open the top of the Whirl-Pak® bag, squeeze out any excess HiCap™ Neutralizing Broth (if using a hydrated sponge), swab the surface, insert the sponge back into the bag, fold the top of the bag over three or more times, and bend in the wire tabs to close. Send to a lab for testing. It’s that easy for trusted results!
