CTech™ FlowVPE® System
In-line process monitoring and control
The CTech™ FlowVPE® System uses the power of Slope Spectroscopy for online process monitoring and PAT fields. Offering process insights and enabling innovation, the FlowVPE helps accelerate development, reduce risk, and increase process efficiency.
Immediate data without sending samples to other labs for analysis
Actionable data to allow for quicker process understanding and design of experiments
Reduced time needed for process development
Easy transfer to later stage processes in Pilot or GMP
No More Sampling
No more long, hold steps for A280, which can take up to 8 hours
Multiple Drug Modalities
Proteins, DNA, Vaccines, AAV
When directly integrated into one or more locations of a process stream, the FlowVPE System reveals process characteristics that, until now, have been hidden due to the limitations of the most commonly-used, on-line, fixed-pathlength UV-Vis solutions.
Capable of making spectral and fixed-point measurements at wavelengths between 190 nm and 1100 nm, at pathlengths between 5 microns and 8 millimeters, the FlowVPE System is adaptable to a wide range of sample types and concentrations. It can support lab scale flow lines of 3 mm, pilot scale flow lines of 10 mm, and manufacturing scale of 22 mm.
The flexibility and robustness of the technology is unparalleled when compared to traditional UV-Vis techniques and equipment.

The FlowVPE System’s in-line variable pathlength system can provide accurate measurement during the downstream process from 0.1 mg/mL to more than 250 mg/mL for an antibody of EC 1.5. No need to remove samples for testing or disrupt production flow.
Drug Antibody Ratio (DAR)
The FlowVPE System can be used to measure the DAR value of antibody drug conjugates (ADC) inline. The software allows the system to measure the ratio between the payload and the protein in real time.
