3M Hydra Sponge – Hermetic bag with moistened sponge for surface sampling with 10 ml Neutralizing buffer

The 3M Hydrated-Sponge with 10 mL Neutralizing Buffer uses simplified packaging to minimize handling and preparation and reduces waste. This sponge is pre-hydrated with Neutralizing Buffer diluent for convenient sample collection. The use of Neutralizing Buffer is advised for surface testing for the presence of microorganisms that may occur on dairy and food equipment disinfected with chlorine or quaternary ammonium salts. The biocide-free cellulose does not interfere with microorganism viability within 48 hours of refrigeration for Salmonella and E. coli and 72 hours for Listeria. The cellulose material is durable, absorbent and effectively holds and releases the sample to minimize excess dripping. The sponge also comes with a double laminated sample bag to ensure strength, puncture resistance, and durability when blending or transporting. Wire ties ensure a secure closure, and a blue top and large white write-on area helps identify the bag. The writable area is ideal for documenting data, date, time of collection, and other information for accuracy, efficiency, and easy identification. Both the sample bag and sponge are decontaminated through gamma irradiation to maintain organism viability and long shelf life.
