Neutralizing Buffer is a convenient and quick collection device for environmental sampling and testing over small surface areas.
Sample collection is easy with the attached swab and the vial has ample headspace for vortexing to release organisms from the swab. This sampling device is decontaminated through gamma irradiation for long shelf life. The 3M Swab Sampler is made in the USA and is ISO 9001:2008 certified for quality assurance. It is intended for lab use only.
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 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 compounds. It is capable of inactivating the bactericidal and bacteriostatic effect of chlorine and quaternary ammonium composites. Neutralizing these chemicals is crucial in accurately detecting the presence of potentially harmful microorganisms. Using Neutralizing Buffer in the microbiological examination of surfaces in standard methods to test dairy products and foods and is also recommended as well as for the digestion and decontamination of mycobacterial specimens.
