BD BBL™ Sterile Pack plated media are in gamma-irradiated packs, validated to performance and sterility according to Association for the Advancement of Medical Instrumentation (AAMI) guidelines. They also feature outer DuPont™ Tyvek® polyethylene wrapping that minimizes the risk of contamination, provides a fiber-free bacterial barrier and allows gas exchange. To use this media, remove the outer wrapping in the noncritical environment, and then remove the sterile inner wrapping in the clean area. The included bag may be used to transport plates from your critical environment. This media must be stored at a temperature of 2°C to 8°C.
