Dry-Bags Enrichment Media greatly reduce the time and labor involved in preparing large volumes of media and diluents. With no handling of glassware or weighing of culture media required, your lab can run more safely and efficiently. And to reduce the burden of QC testing, quality certificates are available for every batch so that you can work confidently.

Save time in preparing bulk media and diluents for food microbiology testing using Thermo Scientific™ Dry-Bags™ Buffered Peptone Water (ISO). The irradiated media is supplied in lightweight, transparent plastic bags — just add water and the medium is ready for use. Each bag makes 20L of medium, which can be dispensed through the outlet tube. .

    Quick and easy to prepare — just add deionized water through filter sterilization to each Dry-Bag, and they are ready to use in minutes. Pre-sterilized water can also be added under aseptic conditions.
  • Cost-Effective
    Light to transport — there is no weighing of media or sterilization required, reducing the burden on media preparation departments and equipment.
  • Safe
    No handling of glassware or weighing of culture media required, no need to add supplementary reagents — empty bags can be disposed of with normal laboratory waste.
  • Quality Guaranteed
    Quality certificates are available for every batch to help reduce the burden of QC testing.
  • Workflow
    Dry-Bags are easily adaptable to laboratory workflows and equipment such as automated diluters.
  • Easy-To-Use
    Dry-Bags are easy to fill and dispense with minimum training.
  • Space-Saving
    Conveniently packed in flat boxes of five or ten, Dry-Bags take up relatively little space compared to prepared media and can be made up as required.
