Process Micro Flow Cells


Out of stock

Process-ready micro flow cells combine with Ocean Optics spectrometers and accessories for online measurement of gas or liquid streams in demanding industrial environments. The cells provide extremely small pathlengths (to 0.02 mm) without restricting sample flow.

With the addition of adjustable optical interface couplers (OICs), the micro flow cells can be adapted to measure high absorbance concentrations (0-50.0 AU) without diluting the sample. Micro flow cells are available in 3/8” and 1/8” diameter, come in stainless steel and other robust materials and have pathlengths ranging from 0.02 mm-2.0 mm. An optional micro flow cell view port allows users to observe the sample stream as it flows through the cell.

  • Short pathlengths – optical pathlengths as small as 0.02 mm for high concentration samples
  • Rugged materials – choose from stainless steel, Titanium and other cell body materials
  • Viewport option – monitor the same stream as it flows through the cell
