Gamma Irradiated Prepared Media

In addition to our standard range of Redipor® media products, we also offer triple-wrapped irradiated settle plates, 90 and 140mm Petri dishes and contact plates. Gamma irradiation extends shelf-life typically to 6 months in ambient conditions. All irradiated products are subjected to the same rigorous quality checks as our standard pre-poured plates. Once packed, they then pass through an additional sterilisation process.
Finally, they are tested after irradiation to confirm growth properties and pH. A detailed certificate of analysis is provided with each batch.Packaging plays an important role in maintaining conditions for the agar and providing consistent, reliable prepared media that delivers confidence in your sampling.
The Redipor triple-wrapped irradiated plates packaging illustration demonstrates the sterility assurance provided by each layer, following exposure to gamma radiation.

The kit contains: a 50ml Tryptic Soy Broth (TSB) injection vial; three empty 30ml sterile injection vials; a 100ml TSB broth bag and one 10ml TSB ampoule.
