QualiTru’s TruDraw® Single Sampler is designed for two ounce samples and virtually eliminates the risk of exposure to external contamination, ensuring sampling accuracy.

The TruDraw works with all TruStream Septa.

TruStream and TruMotion Sterile collection bags

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 TruStream sterile collection bags come in a variety of sizes and configurations for any sampling need.
The TruMotion™ Collection Bags are designed to work with peristaltic pumps, creating a continuous flow sampling system that collects a composite sample over an entire process run.
