Designed to meet stringent laboratory testing needs, this pouch has the strength needed to endure sample preparation and handling processes. Pre-measured with 225 mL of enrichment broth, the pouch is ready to use with no mixing required. Just add the sample, homogenize to mix, then place directly into the incubator. The broth and pouch are decontaminated through gamma irradiation to maintain organism viability and long shelf life. The flat bottom allows the pouch to stand on its own and heavy gage wire closure holds the pouch open, allowing the technician to work with both hands. Once the desired sample has been added, the open top is folded over itself and the wire tie bent over the fold to seal. The multi-layer pouch is strong enough to use with a paddle blender to effectively mix the sample with the enrichment solution. This product is made in the USA with globally sourced materials and is ISO 9001:2008 certified for quality assurance. It is intended for lab use only.

Lactose Broth is often used as a pre-enrichment medium when testing foods and dairy products for Salmonella spp. Salmonellaspecies may be sub-lethally injured and in low numbers in dried or processed foods. The occurrence of other bacteria as well as components of the food sample may deter growth and recuperation of Salmonella. Pre-enrichment in a Lactose Broth allows for repair of cell damage, dilutes toxic or inhibitory substances, and provides a nutritional advantage to Salmonella over other bacteria. Lactose Broth is widely used and is included in many procedures for testing foods, dairy products and other materials.
