More details




Q Swab Universal Neutralizing Medium (Letheen) 


Q-Swab is a ready-to-use sample collection and delivery device for environmental surface sampling. Simply collect an environmental sample and snap the bulb at the top of the device to release 1mL of media into the sample. The media neutralizes residual sanitizers and facilitates recovery of bacteria*. A variety of different medias are available depending on bacteria of concern. After activation, the sample is ready to be poured onto sample-ready media film or streaked onto plates for culturing. Q-Swab can be used either wet or dry to sample surfaces. 

 *Only Letheen media neutralizes residual sanitizers. 

Q-Swab combines all the elements of traditional sample collection into one modern, convenient device. By eliminating sponges, bags, and pipettes, Q-Swab minimizes materials and labor. With common broth options, Q-Swab is a perfect sample collection solution. Q-Swab contains the perfect amount of media to rehydrate one agar plate or dehydrated media film without any waste. For sample collection and dilution devices with larger volumes.
