A Unique and Patented Variable Pathlength Technology (VPT)

Providing a more efficient method for analyzing at-line and in-line processes, slope spectroscopy is a UV-based technology that serves as an alternative to the Beer-Lambert Law that focuses on pathlength as the variable that determines concentration.

Our Real-time Process Management (RPM™) Systems establish a new benchmark for real-time process control in downstream bioprocessing by integrating of the CTech™ FlowVPX^® in-line UV-Vis spectrophotometer into the KrosFlo^® TFF Systems. This innovative solution empowers users to achieve unparalleled control and optimization of UF/DF processes, driving efficiency, quality, and innovation in biomanufacturing.

In-line GMP testing

Designed to meet the rigors of regulatory GMP requirements, the new CTech^™ FlowVPX^® spectrophotometer system offers reliable real-time results with integrated ease for concentration measurements during every stage of the downstream GMP process.

At-line GMP and non-GMP testing

The CTech™ SoloVPE^® System unlocks the power of Slope Spectroscopy with its unique and patented variable pathlength technology (VPT). Avoid costly dilution with this simple, yet empowering variable pathlength solution that delivers rapid and accurate results.

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.

Elevate your lab with top-of-the-line consumables tailored for the SoloVPE and FlowVPX systems, ensuring pristine measurements and accuracy in your scientific endeavors.

ELISA Kits from Repligen deliver the precision, reproducibility, and sensitivity required for the accurate quantitation of leached native Protein A, recombinant Protein A, the MabSelect SuRe™ ligand, the NGL-Impact® ligands, AVIPure ligands, and LONG® R3 IGF-I.
