Whatman™ Swabchek™ Specimen Collection Swabs & Transport Systems

The Swabchek™ Principle:The surface is wiped with a cellulose swab and any bacteria collected are transferred via the swab into a tube containing a special medium with an indicator dye, which is then incubated. A single bacterium is sufficient to cause a color change. This means that Swabchek™ is about 1000 times more sensitive than the conventional ATP method. This accuracy is particularly important in the food industry. With this simple method, it is possible to identify microorganisms such as Listeria monocytogenes, which must not be present in any concentration in food and beverages.

Swabchek™ Specimen Collection Swabs & Transport Tubes:These swabs are used as an indication of hygiene on contact surfaces. A Swabchek™ swab changes color from purple to yellow. The color change is based on acid reaction with the indicator. The more rapid the color change, the higher the level of bacteria in the sample. Swabchek™ specimen collection swabs are useful in determining the sanitation levels of preparation surfaces, filling ports, and processing areas in beverage and food processing plants, dairies, restaurants, and healthcare facilities. Swabs offer the right test for each type of contamination and are pre-sterilized and ready for immediate use. Ideal for qualitative and semi-qualitative hygiene control with rapid results and a long shelf life.

Swabchek™ Neutralizing Buffer Swabs:These buffer swabs are used in the monitoring of surfaces for total bacterial count. Neutralizing buffer inactivates the bactericidal and bacteriostatic effects of chlorine and quaternary ammonium detergents. However, neutralizing buffer exhibits no toxic effects on microorganisms. This permits the transfer of swabbed organisms to the laboratory without loss in viability. Neutralizing buffer is not designed to culture and enumerate microorganisms.

Swabchek™ Buffer Swabs:These swabs are used for the collection of surface contamination from flat or convoluted surfaces prior to transport to a laboratory for culture and enumeration. Swabchek™ Buffer Swabs contain no bacteriostatic or bactericidal compounds and cannot suppress the action of detergents.

Swabchek™ Polywipe Sponge:Sponges are used for the recovery of microorganisms from a surface. Swabchek™ Polywipe is a blue sponge that is pre-moistened with neutralizing buffer to neutralize the effects of surface disinfectants. The sponge material is selected to be free of the preservatives found in commercially available sponges, which can inhibit microorganism growth. Polywipe sponges are biocide free and tested for zero toxicity to microorganisms. Each sponge is individually wrapped in a peel pouch and gamma irradiated to ensure sterility.
