Collect and enrich with 1 device

PUR-Blue™ DUO Swab Samplers combine practical convenience with sound microbiology.  DUO is designed to facilitate the collection and enrichment of pathogens with a single device.  One tube of the DUO contains a polyurethane tip swab hydrated with a neutralizing media.  The second tube contains a ready-to-use enrichment broth for recovery and growth of target organisms such as Listeria or Salmonella. With the PUR-Blue DUO, enrichment can start immediately after collection, eliminating handling and transfer in the laboratory.


  • Sample collection and enrichment in 1 device.
  • Eliminates transfer step – saves time and labor in the laboratory.
  • Reduces enrichment media costs.
  • More cost effective than sponge sampling devices.
