The Oxford Instruments Hostaphan High-Performance XRF Sample Film is a laboratory-grade consumable designed for precise X-Ray Fluorescence spectroscopy. Manufactured from ultra-pure Hostaphan polyester, this film provides outstanding clarity, low contamination, and minimal spectral interference — essential for accurate trace elemental measurement.

Its 3.5 µm thickness delivers optimal X-ray transparency while maintaining tensile strength and sample containment integrity. Supplied in a 100m roll, the film supports high-throughput sample preparation in both benchtop and automated XRF systems.

Perfect for laboratories performing routine QC, research analysis, and multi-element detection across various industrial sectors.
