The 3M Enrichment Pouch with 225 mL Buffered Peptone Water Broth with Filter
is a heavyweight, puncture-resistant pouch that is ideal for many sample
preparation and enrichment procedures. The inner filter is designed to allow for
the flow of microorganisms but not large food particles to minimize clogging of
the sampling pipette. The filter spans the entire width of the pouch and is
attached at the sides and bottom for easier pipetting.
Designed to meet stringent laboratory testing needs, The 3M Enrichment Pouch
has the strength 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.
