PendoTECH Single Use UV Flow Cell

In bioprocess operations, the UV absorbance of a liquid solution can identify the absence or presence of the molecule of interest. The measurement, typically 280nm, is made by a spectrophotometer either in-line of off-line in a cuvette. A collimated beam of light passes through a sample with a defined path length and the absorbance is determined as the ratio of the light applied from the source to what passed through the sample. The PendoTECH Single Use UV Flow Cell enables the measurement to be made non-invasively. The flow cell may be part of single use process assembly made up of tubing, bags, filters, and other sensors and the measurement is made by a by use of a compact spectrophotometer with fiber optic cables. This flow cell contains a special glass window on the wall and compartments to attach the light source and detector. The stream to be measured flows between the windows by way of tubing attached to the hose barb ends of the flow cell. Even though designed for single use, the design is robust enough to be re-used.
