Abstract

Apparatus and assemblies for automated sterile collection of urine and other biomaterials for medical testing, law enforcement testing, etc. Individual sample collection cartridges include an inflatable collection conduit and an inflatable collection vessel. The collection vessel can be sealed in multiple locations in a chronologically sequential manner to segregate an initial or “dirty” portion of a urine stream.
