Cross-section view of a bioreactor, showing a SCHOTT ViewPort™ for Bioprocessing


These revolutionary process analytical technology (PAT) components act as sensor receptacles on bioreactors, enabling in-situ bioprocess monitoring through hermetically sealed optical windows without compromising the sterile boundary. This leads to reduced contamination risk and higher process yield.

PAT: for preventing contamination

In contrast to existing physical sampling methods that require opening the bioreactor to take samples out or insert probes, ViewPort® receptacles enable safe and sterile in-situ process measurements through optical windows. This helps to minimize contamination risk.

ViewPort three reactors

Optimized yield and process automation

ViewPort® components allow easy and continuous measuring of key process parameters via the optical interface. This enables real-time adaptation of processes, which leads to increased yield. Options for lab-scale, stainless steel and single-use bioreactor systems allow upscaling from process development to production scale.
