Common Platform
Finally a system to measure concentration that is analyst & site independent while easily transferable from Discovery to the Manufacturing Floor and QC
Pathlength Range: 0.005-15mm
Accuracy and Repeatability: +/-2%
Concentration Range : 0.01-300mg/mL
Minimum Volume : 20uL
Wavelength Range: 190-1100nm
Accurate concentration reading in less than one minute vs. hours of serial or gravimetric dilution


C Technologies, Inc. is a privately owned company since 1985 whose inception came about from the need for high quality specialty fiber optic assemblies. These fiber optic assemblies spurred the idea for a Variable Pathlength Extension, becoming the foundation for Slope Spectroscopy and the SoloVPE. The SoloVPE has changed the field of UV-Vis Spectrophotometry, something that hasn’t changed significantly for over 40 years. The SoloVPE and Slope Spectroscopy method offers a quick, user-friendly technique for measuring concentration that is accurate and robust, providing pharma companies a common UV platform that can be implemented across multiple sites and countries. Now, with the upcoming release of the FlowVPE, this same proven method can be put online for accurate real-time concentration measurements. C Technologies, Inc. believes that success comes from providing products to simplify the scientist’s workload and by providing unparalleled service and support for their customers.
