Traditional UV/Vis spectroscopy uses fixed pathlengths to measure different analytes, such as nucleic acids, proteins, and cells from biological samples. These samples are often limited in volume or highly concentrated, which presents various challenges.

The CTech™ SoloVPE® System uses patented variable pathlength technology (VPT) to accurately measure the targeted concentration of various analytes in less than 2 minutes. The system can measure concentrations without being dependent on sample volume or sample concentration, removing any dilution requirements.

In this webinar, we will review VPT and how it can be used in various applications from protein to nucleic acid therapeutics. We will share real-world case studies demonstrating how companies have integrated the SoloVPE System into their manufacturing workflow for release and in-process testing.
