• Often considered the closest thing to a “bombproof” XRF window film.
• Incredibly strong and heat resistant to over 300 °C (572 ºF).
• Chemically impervious to almost anything except strong alkali solutions.
• Phosphate-based surface coating improves its handling characteristics.
• 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.
