In-line Flow Cells
For in-line absorbance or fluorescence measurements, Avantes offers the in-line flow cells. They are available for tubing diameters of 1/4, 1/2 and 1 inch. The flow cells consist of Swagelok union cross tube fittings and two UV/VIS/NIR collimating lenses.
The optical path depends on the size of the flow cell: the 1/4” version has an optical path of 5 mm, the 1/2” of 10 mm and the 1” version 20 mm. They feature SMA-905 connectors for easy coupling to any of our wide range of fiber-optic cables or bundles.
All flow cells come with variable focusing to optimize light throughput over the spectral range. All flow cells are also available in high temperature configurations (up to 200°C). Special flow cells for gasses and liquids are also available and are designed to withstand pressures up to 100 bar.
