Thin window film for XRF liquid sample cups

  • Compatible with X-Cell® sample cups

Cole-Parmer® XRF window film serves as the sample window over our X-Cell sample cups, allowing for uniform transmission of x-rays while effectively containing the liquid sample.

Kapton® polyimide film is chemically imperious to almost anything except strong alkali solutions. It is often considered the closest thing to a bombproof XRF window film due to its incredible strength and heat resistance to over 300°C (572° F). The phosphate-based surface coating improves its handling characteristics.

BoPET (Mylar®) film is unusually strong for its thickness, it is resistant to organic chemicals but vulnerable to strong acids and bases. It may contain trace levels (ppm) of Ca, P, Fe, Cu, Zn, or Sb.

Polypropylene film is reasonably resistant to acids, bases, and many organic chemicals, but can be attacked by aromatic and halogenated hydrocarbons. It may contain trace levels (ppm) of Ca, Zr, P, Fe, Zn, Cu, Ti, and Al.

Ultralene® film offers the best balance between X-ray transmission, chemical resistivity, strength, and purity. The 4 µm (0.16 mil) thickness allows for a greater degree of X-ray transmission and makes it ideal for light-element analysis. It is heat resistant up to 100°C (212°F) and is reasonably resistant to acids, bases, and many organic chemicals, but can be attacked by aromatic and halogenated hydrocarbons.
