In-Line UV & Turbidity
The Single-Use UV Flow Cells with a compact PM2 photometer and fiber optic cables measure UV absorbance in filtration and chromatography applications without product contact. The Turbidity Flow Cells and PM2 Photometer measure the turbidity of unclarified material from a bioreactor or fermentor or after it flows through a filter, providing consistent filter performance monitoring.
The Single-Use UV Flow Cells are cost-effective for disposable applications but can be cleaned and reused. The UV and Turbidity transmitters can be integrated into a monitor with data acquisition capability or a control system, offering a 2-in-1 solution. A dual-wavelength unit is available for increased versatility, and two parallel measurements can be made with one flow cell.

Pendotech Single-Use UV Absorbance Sensors
In bioprocess operations, the UV absorbance of a liquid solution can identify either the absence or presence of the molecule of interest. The measurement, typically at 280nm, is made by a spectrophotometer either in-line or 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. It is cost-effective for single-use applications and can be repeatedly cleaned and reused. The flow cell is easily integrated into tubing, and the measurement is made using a compact photometer 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 through tubing attached to the hose barb ends of the flow cell.
