Single-Use In-line
UV Absorbance PhotoMeter
Single-Use UV Flow Cell
The flow cell is connected to tubing, and the measurement is made by use of a compact photometer with fiber optic cables. This flow cell contains a special silica glass lens on the wall and compartments to attach the light source and detector.
Non-Invasive Measurement
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.
Overview
Streamline your process with PendoTECH In-line Single-Use UV Absorbance Photometer that collects data from the bioprocess fluid streams, while it is processing, resulting in less disruption to bioprocessing operations compared to measurements taken off-line. The Single-Use UV Flow Cells coupled with a compact photometer with fiber optic cables to measure the UV absorbance in filtration and chromatography applications without product contact. Additionally, stainless steel flow cell options are available.
