CTech™ SoloVPE® PLUS System Product Specifications Specification Sheet Overview The CTech SoloVPE® PLUS System is an enhanced version of the SoloVPE System, offering faster performance and an extended concentration measurement range without the need for dilution. Building on our unique and patented Variable Pathlength Technology (VPT), the SoloVPE PLUS System elevates the user's experience with time savings and ease of use while maintaining the high accuracy and precision valued by leading biologic manufacturing companies for rapid at-line concentration measurement. Unlike traditional UV-Vis methods that generate a single absorbance result, the Slope Spectroscopy® method characterizes samples using multiple absorbance data points acquired at different pathlengths. The absorbance vs. pathlength data are verified in real-time for linearity in compliance with the Beer-Lambert law. The slope of the line is directly proportional to the sample concentration and extinction coefficient, delivering results in under a minute without the need for dilution or background correction. The SoloVPE PLUS System measures wavelengths from 190 nm to 1100 nm and pathlengths from 0.002 mm to 15.000 mm, accommodating various sample types and concentrations with proven accuracy and repeatability across systems, operators, and sites. Invest in the SoloVPE PLUS System to future-proof your lab, expand your capabilities, and stay at the forefront of analytical technology. repligen.com © 2024 Repligen Corporation.

CTech SoloVPE® PLUS System Specification Sheet Features | Benefits No Dilution Measure highly concentrated samples directly without dilution. Eliminate Background Correction Buffer/background correction is only required in special circumstances. Rapid Results Concentration results can be obtained typically in less than one minute. Volume requirements range from <20 μl to 2.5 ml, depending on method and sample vessel. Slope Spectroscopy Method Slope-based measurements utilize multiple data points instead of a single absorbance value. No reference standard is required for quantitation. Rapid Sample...
