Make environmental surface sampling faster and easier with Whirl-Pak polyurethane surface sampling bags with premoistened sponge. The 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
• Write-on label makes identifying samples easy and convenient
• Sponge is hydrated with 10 ml of HiCap™ neutralizing broth
• Terminally gamma processed to guarantee sterility (+1 Sterilization)

To use the sponge, tear open the top of the Whirl-Pak® bag, squeeze out any excess HiCap™ Neutralizing Broth, 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.
