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 5mm, the 1/2” of 10mm, and the 1” version has a 20mm optical path. They feature SMA-905 connectors for easy coupling to any of our wide range of fibre-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.
