The 3M Enrichment Pouch with 225 mL Buffered Peptone Water Broth
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.
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. Tryptic Soy
Broth (Soybean-Casein Digest Medium) is a general purpose liquid medium used as
an enrichment broth in qualitative procedures to cultivate aerobic
microorganisms that are not necessarily fragile and will readily grow in this
enrichment broth. It is a nutritious medium that will support the growth of a
wide variety of microorganisms, especially common aerobic and commonly
associated anaerobic bacteria. In clinical microbiology, it may be used for the
suspension, enrichment and cultivation of strains isolated on other media.
