LPC Longpass Flow Cells couple to Ocean Optics spectrometers and light sources for measurement of low-volume and low-concentration aqueous samples. The cells are available in standard and microvolume versions, with pathlengths ranging from 1 cm-500 cm and internal volume levels from 2.4 µL-1,250 µL.

LPCs use a capillary tube as both sample compartment and light waveguide. Chemical and biological samples such as proteins, nutrients and DNA are introduced with a syringe or a pump into the fluidic ports mounted on the face panel. Optical fibers connect to SMA 905 fittings to deliver and return light to the spectrometer.

  • Small volume sampling – microcell options with internal volume as low as 2.4 µL
  • Multiple pathlengths – options ranging from 1 cm to 500 cm
  • Easy to use – inject sample with a syringe or connect to a pump
