• 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

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).
