SCHOTT ViewPort™ for Bioprocessing

SCHOTT ViewPort™ interfaces are metal conduits with hermetically sealed-in optical windows, allowing outside optical sensors to measure the physical and chemical parameters of the reactant through the window. The devices can be soundly integrated into the bioreactor, with their gas-tight design able to prevent intrusion of bacteria or fungi into, as well as leakage out of, the reactor. ViewPort™ components are manufactured using materials according to pharma industry best practices, making qualification a simple process.

Enabling measurements while maintaining a sterile boundary

Processing risk minimization

SCHOTT ViewPort™ can be securely attached to stainless steel multi-use bioreactors (MUBs) and maintain long-term gas-tightness and hermeticity. The device keeps the integrity of the sterile boundary intact to help prevent contamination.


The components are sterilizable under γ-radiation and steam-in-place (SIP) together with the entire bioreactors. They increase the usability of spectroscopic techniques in bioprocesses by removing the additional sterilization requirement for the spectrometer probe.

High-performance optical measurements

Made with high-quality SCHOTT glass, the optical window enables the precise transmission of optical signals between sensors and reactants.

Approved materials

SCHOTT ViewPort™ sensor receptacles conform with applicable regulations and guidelines. All components are manufactured using metal, glass, sapphire, and other materials according to pharma industry best practices.
