DuPont™ StatMedia™ Soluble Packets Provide Fast and Flexible Enrichment Preparation for Food Testing Labs

DuPont Qualicon recently introduced DuPont™ StatMedia™ soluble packets, a new delivery system that makes preparing enrichment broth for the food testing industry fast, flexible and easy. The packets are unit-dose volumes of pre-measured microbial nutrients wrapped in a water-soluble film. Proprietary BAX® system MP medium for enriching E. coli O157:H7 is available in StatMedia™ soluble packets, along with Buffered Peptone Water for non-selective enrichment. Both come in a variety of convenient weights to accommodate the workflow of food testing labs.

DuPont has several decades of experience with packaging products in water-soluble film for a variety of markets. Qualicon has leveraged that experience to bring increased value to food testing labs. With StatMedia™ soluble packets, there’s no measuring, no mess, no spills, no dust. Users simply drop the packet into a sterile container with sterile water and mix as usual. The film dissolves within seconds and does not interfere with bacterial growth or PCR processing, according to Dr. Shawn Anderson, StatMedia™ Product Development Manager.

Most StatMedia™ soluble packets are also gamma-irradiated. This means that prepared enrichment broth does not require autoclaving when used within four hours.

“Many laboratories will appreciate the time, labor and energy savings that result when they don’t have to weigh the media and use the autoclave,” said Ravi Ramadhar, global marketing manager for DuPont Qualicon. “By simplifying enrichment preparation, StatMedia™ soluble packets help to improve food testing efficiency.”

DuPont Qualicon provides innovative, science-based diagnostic products. The BAX® system offers advanced DNA-based detection of microbes in food, from raw ingredients to finished products. The new BAX® system Q7 now offers real-time PCR assays that provide multiplex detection with quantitative results. DuPont Qualicon also markets the patented RiboPrinter® System, the world’s only automated DNA fingerprinting instrument that rapidly pinpoints sources of bacteria in pharmaceuticals, personal care products and food.
