Simplifying control in complex workflows
Pendotech offers a comprehensive suite of in-line, single-use monitoring solutions designed to give you total confidence in your bioprocessing workflows. By integrating high-precision Single-Use Pressure, Temperature, and Conductivity sensors with the reliable analytical power of the PressureMAT Sensor Monitor and Conductivity Monitor, this system provides a clear, real-time window into your process stability. To ensure complete fluid quality, the Turbidity Photometer and Single-Use In-line UV Absorbance Photometer provide non-invasive optical data, allowing you to monitor protein concentration and fluid clarity without the need for manual sampling or the risk of contamination. These tools work together to simplify your path from discovery to commercial-scale production, reducing the burden of cleaning and validation so you can focus on what’s important: your product.
Applications:
- Chromatography & Fractionation: Correlate UV Absorbance with Conductivity shifts to automate fraction collection and improve purity.
- Filtration & Integrity: Use the PressureMAT and Turbidity Photometer to detect breakthrough early and protect high-value membranes.
- Buffer & Media Preparation: Ensure formulations meet exact specifications with temperature-compensated Conductivity and Temperature monitoring.
- TFF / Cross-Flow Control: Optimize flux rates and concentration stability by tracking feed, retentate, and permeate pressures in real-time.
- Closed-Loop Integrity: Maintain sterility with non-invasive sensors that eliminate the need for manual sampling and post-run validation.
