• The Ultra Short Path flow cells are intended for measurements on optically dense (highly colored) solutions. This is made possible by a design that can accommodate extremely short optical path lengths. Wetted materials on the USP flow cell are quartz, PEEK or Delrin, and PTFE. Available optical path lengths are 0.1, 0.2, 0.5, 1.0 and 2.0 mm.

    Popular applications include:

    • measurement of dye concentrates
    • measurement of high-concentration protein solutions

    Warning: Note that Sequential Injection Analysis and Flow Injection Analysis systems, for which the FIAlab-Z cell has been designed (for example, the FIAlab® series), operate in such a way that the cell is exposed to aggressive materials only intermittently and for short periods of time. Most of the time the system is washed between samples or filled with water when idle. Prolonged exposure of the cell to corrosive chemicals may eventually lead to leaking or damage to flow cell, fittings, or windows, and voids the warranty.

  • Assembly Instructions:


    Your flowcell is shipped fully assembled and ready to use. However there may be occasions where you want to disassemble the flowcell, for instance to change optical paths. 1) The flowthrough “slide” needs to be oriented so that the small port holes face upwards, and lay the slide in the recessed area, as in the two photos below. 2) Screw the upper and lower slide mounting plates together with the four included screws, as shown below. WARNING: rotate from one screw to the next, gradually tightening all four. This insures the plates are mounted level. WARNING: do not over tighten. The plates only need to press against the slide to hold it in place. Over tightening can crack the slide. 3) Pretighten/collapse the blue ferrule onto the tubing. This step is performed because it takes some force to tighten the blue ferrules, a process that could crack the slide (step 5). So the blue ferrule must be pre-tightened using a different ¼-28 port. 4) Drop one Teflon gasket (included) into each of the two fluidic ports (as shown below), making sure they lay flat at the bottom. 5) Mount the tubing into the fluidic ports with the included ¼-28 flat bottom fittings and blue ferrules. Make sure the tubing does not extend past the blue ferrule’s flat bottom. WARNING: DO NOT OVER TIGHTEN. Over tightening will crack the slide. Just half a rotation past the point of first resistance is adequate. So the blue ferrule is pushing up against the white Teflon seal firmly but not tight. The flat bottom pushed against the white Teflon gasket makes a good seal.

SMA-WIN Kits
Replacement Seal and Windows

You will need to clean your flow cell to preserve its longevity. We recommend cleaning it once every three months. Most of our customers, however, clean them every six months.

After each cleaning, it is necessary that you replace the Teflon seals. This will ensure a watertight seal. For the best optical performance, exchange the silica windows every half-year.

We supply these consumables in the SMA-WIN Kit (PN 79150). This packet includes two silica windows, six Teflon seals, and a scrubbing brush. A separate kit with two new SMA adapters also exists. This is the SMA-WIN-SS Kit (PN 79153).
