The TruStream oxygen-permeable collection bag provides a sterile fluid path and is equipped with a needle and tubing and works with all TruStream septa. The sterile collection unit extends aseptic sampling, while the oxygen permeability allows for the incubation of the product. The incubation period allows bacterial growth to accelerate, thus detecting and locating the source of potential inline contamination. The TruStream sterile collection bags come in a variety of sizes and configurations for any sampling need. QualiTru also offers TruMotion Collection Bags designed to work with peristaltic pumps.
