UV-vis spectrophotometer CTech™ SoloVPE® PLUS

UVfor the pharmaceutical industryfor protein quantification

The new CTech™ SoloVPE® PLUS System features patented variable pathlength technology (VPT), providing precise concentration measurements with no need for costly dilutions. This reliable solution delivers fast, accurate results with system-to-system, operator-to-operator, and site-to-site consistency, ensuring high-quality performance across various bioprocessing applications. Unlike the single value dependence of legacy UV-Vis methods, the data-dense slope method characterizes samples by collecting multiple absorbance data points at several pathlengths to create a section curve (absorbance vs. pathlength plot). The section curve is then analyzed in real time to verify linearity in compliance with the Beer-Lambert law. The linear region of the section curve is directly proportional to the concentration of the sample based upon the sample extinction coefficient. The result? The SoloVPE PLUS System reports concentration results in less than 30 seconds. Capable of making spectral and fixed-point measurements at wavelengths between 190 nm and 1100 nm at pathlengths between 2 microns and 15 millimeters, the SoloVPE PLUS solution is adaptable to a wide range of sample types and concentrations. The variable pathlength spectroscopy method has been proven to be accurate, precise, and robust. Therefore, it can easily and successfully be validated in accordance with ICH Q2(R1) requirements. The variable pathlength technology allows R2 values of ≥0.999, proving the robust system-to-system consistency. Key Features Slope Spectroscopy Methods: The first and only slope spectrometer, capable of Slope Spectroscopy-based measurements.
