3525 - Ultralene® Thin Film (Roll), 0.16 mil

• Considered to offer the best balance between X-ray transmission, chemical resistivity, strength, and purity.
• 4 µm thickness allows for a greater degree of X-ray transmissionand makes it ideal for light-element analysis.
• Reasonably resistant to acids, bases, and many organic chemicals,but can be attacked by aromatic and halogenated hydrocarbons.
• Heat resistant up to 100 °C (212 ºF).
• Box has a serrated edge for tearing thin window film to desired length.

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.
