Cole-Parmer™ Ultralene XRF Window Film

• Ideal for light-element analysis.
• Heat resistant up to 100°C (212°F).
• Reasonably chemically resistant.
• 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.
• 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.

Order Info Available in a variety of materials, each resistant to a range of chemicals. All sizes are compatible with X-Cell sample cups.
