ABSTRACT:
An apparatus for monitoring a chemical process or fermentation having a flow-through vial which includes a container having a specimen sampling opening and an inlet port and an outlet port defining an internal flow path through which liquid specimen is circulated from a chemical process. A self-sealing septum is adapted to seal off the sampling opening, and a cap having an orifice is engaged with the container, holding the septum in sealing relationship over the sampling opening. Specimen, which reflects current conditions within the chemical process, is periodically aspirated from the vial by extending a hollow needle through the orifice, septum and sampling opening and into the internal flow path.
