  • One opening for fast liquid sample delivery.
  • Compatible with major suppliers of XRF spectrometers.

  • Contaminant-free polyethylene construction.
  • Collars available to attach window film to cup for added security.

Cole-Parmer™ X-Cells are used throughout the world for fast, dependable, reproducible running of liquid samples in XRF spectrometers.

  • They are designed to fit into the major suppliers of XRF spectrophotometers, such as PANalytical, Rigaku, Bruker, and Thermo Instruments.
  • The durable polyethylene construction is generally resistant to acids, bases, and most organic chemicals except halogenated hydrocarbons.
  • The patented closed X-Cell design features a snap-open seal for venting volatile samples and a reservoir cup for catching any liquids that expands through the vent.
  • This assures the analyst of a smooth, fat window for improved precision, yet guards against spillage in inverted-optic spectrometers.
  • A roughed surface within the reservoir cup facilitates labeling.
  • Each closed X-Cell consists of a cup and snap-on ring.
  • For routine liquid samples, the cup is filled with liquid, a piece of film is spready over the top, then the snap-ring is pushed down over the cup to form a fat drum-like window.
    • The cell is turned over and, if desired, the snap-post on the rear can be pushed to break the seal and to permit venting of trapped bubbles and expand liquid while the sample is run.
    • The filled X-Cell is then positioned in the spectrometer mask.
  • Use the bubble-free insert with the 3527 (04576-05) 40 mm XRF liquid cell to prevent trapped air from forming a bubble under the window film when the cell is upright.
    • The insert is pushed into the cell before the sample is added and forms an inverted-cone shelf under which air bubbles can be trapped once the cell is filled and sealed.
