Welcome to UV Absorbance Sensor page.

In bioprocess operations, the UV absorbance of a liquid solution can identify 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.
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.
