Ultralene Window Film 0.16 mil (4 m) Thick, 2 7/8 in Wide; 300 ft

Thin window film for XRF liquid sample cups|Ideal for light-element analysis Heat resistant up to 100 C (212 F) Reasonably chemically resistant Compatible with X-Cell sample cups|Supplied as continuous roll 2 7/8 in (73 mm) wide, 300 ft long|Spex SamplePrep 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. Ultralene film offers the best balance between X-ray transmission, chemical resistivity, strength, and purity. The 4 m (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 100C (212F) and is reasonably resistant to acids, bases, and many organic chemicals, but can be attacked by aromatic and halogenated hydrocarbons.
