Choosing a sampling sponge

When determining which sampling sponge to use, it’s important to consider certain factors in your testing process.

Bacteria – Release of bacteria from the swab/sponge for quantitative measure. Subsequent cultivation Cellulose and polyurethane sponges are proven to be equivalent for sampling environmental surfaces*ƚ.

Biocide – Biocide-free cellulose sponge maintains viability for a wide range of organisms. Listeria can be maintained for up to 72 hours of refrigeration*.

Environment – Cellulose sponges are made from renewable biomass. Polyurethane sponges are made from petroleum byproducts through a reaction of polyols, diisocyanates, catalysts and additives.

Strength – 3M cellulose sponges are tested to withstand scrubbing on multiple surfaces.

Consistency – 3M sponges made with cellulose raw material are sorted during inspection to ensure consistency of chemical and mechanical properties from batch to batch*.

Temperature – Letheen is stable at ambient storage temperature for up to 2 months*. Neutralizing buffer is stable at ambient storage temperature*.
