3M™ Swab-Sampler with 1 mL Letheen Broth is a convenient and quick collection device for environmental sampling and testing over small surface areas.
Sample collection is easy with the attached swab. The vial provides ample headspace for sample addition and vortexing to release organisms from the swab. This sampling device is decontaminated through gamma irradiation for long shelf life. The Hazard Analysis Critical Control Point (HACCP) approach is the most widely accepted food safety management protocol worldwide. Sample collection products from 3M are a crucial part of this approach to identify potential food-borne hazards and pinpoint where they reside. Portability, stable enrichment media, and easy-to-handle swabs and sponges are designed to test for a wide variety of potential hazards and deliver exceptionally accurate results. They are engineered to safely gather, hold, and secure contents from the collection site to the lab without leaking or compromising the sample. The primary use of Letheen Broth is to neutralize the bactericidal action of quaternary ammonium compounds, and for determining the phenol co-efficient of cationic surfactants per the recommendation by the Official Methods of Analysis of the Association of Official Analytical Chemists (AOAC). Letheen Broth is also used in hygiene swabbing practices where neutralizing quaternary ammonium compounds are required.
