The ultimate in environmental sampling PURITAN EnviroMax Plus ® EnviroMax Plus PURITAN ® The ultimate in environmental sampling EnviroMax Plus® is a larger size pointed foam-tip sampling swab, premoistened with Neutralising Buffer. Ready to use in its large safe orange capped tube, robust and easy to carry to the sampling site, then convenient to transport to the testing laboratory. The large super-absorbent foam head on EnviroMax Plus® ensures collection of an adequate sample for the detection of surviving microorganisms on food contact surfaces, when these maybe unevenly distributed following cleaning. The neutralisers cancel the effects of leftover traces of chlorine and quaternary ammonium compounds. Neutralising Buffer is a recommended wetting agent for the swabbing of dairy and food equipment1,2. The solution inactivates the bactericidal and bacteriostatic effects of chlorine and quaternary ammonium based reagents, ensuring that any surviving microorganisms can be reliably detected. The swab shaft of EnviroMax Plus® features a paddle-shaped end underneath the foam head. At the other end the shaft is securely mounted in the large bright-orange cap. These features make the device very easy to handle and manipulate, while the pointed foam head is ideal for sampling larger Catch and Release areas, and equipment parts. The clear tube and orange cap are made from shatterproof plastic, so there is no risk of splinters in critical production areas. The “chunky” cap requires just a quarter turn to open, and yet closes securely. Other than the premoistening buffer on the pointed foam head, there is no additional liquid in the tube. On receipt at the laboratory, testing of EnviroMax Plus® can be by conventional culture based methods, and the sample should Paddle Structure also be suitable for any advanced molecular techniques, although these must always be accompanied by adequate controls. It is simple to add any test liquids to the tube, such as chromogenic broths for specific target pathogens. The white foam tip Hi-White Foam Tip and Shaft provides an ideal background for the early observation of any colorimetric changes. In house studies have shown excellent recoveries for at least 48 hours of Escherichia coli, Salmonella enteritidis, Listeria monocytogenes, Listeria inocula, Listeria grayii, and Staphylococcus aureus. Studies have also shown good performance with proprietary liquid chromogenic media for Salmonella and Listeria. EnviroMax Plus® can be stored at ambient or refrigerated temperatures. References: 1.
