SciAps X-505 Replacement Measurement Windows – Prolene & Kapton Options

These replacement measurement windows are designed for use with the SciAps X-505 Handheld XRF Analyzer and are manufactured by Alloy Geek to support reliable, repeatable field testing across soil, mining, and materials analysis applications.

Measurement windows are a consumable component on handheld XRF analyzers and should be replaced periodically to maintain analytical performance and protect the detector assembly. Alloy Geek offers two window material options—Prolene and Kapton—to match different testing environments and sample types.

This product listing allows you to select the appropriate window type based on what your X-505 has been calibrated to use. Please use the same type of window that came with your handheld XRF.

Available XRF Window Options

Prolene Measurement Window

Prolene windows are optimized for applications where light element sensitivity is important and minimal X-ray attenuation is desired. They are much thinner than the Kapton windows. Used for:

• Alloy Testing (allows Light Elements)
• Soil contamination screening
• Environmental site assessments
• Mining and geochemistry applications
• Situations where maximizing sensitivity to lighter elements is beneficial

Kapton Measurement Window

Kapton windows provide greater mechanical durability and resistance to tearing, making them well suited for harsher field conditions. Used for:

• Rugged field environments such as soil testing
• Alloy testing where light elements are not required
• Applications where window longevity is prioritized over maximum light-element sensitivity

Compatibility

• Designed for use with SciAps X-505 Handheld XRF Analyzers
• Precision-cut to fit the X-505 measurement window faceplate
• Compatible with soil sample cups, films, and test stand use

Why Replace Measurement Windows?

Measurement windows protect the detector while allowing X-rays to pass through to the sample. Over time, windows may become:

• Punctured or torn
• Stretched or fatigued
• Contaminated with dust, soil, or residues

Replacing worn windows helps maintain:

• Analytical accuracy
• Repeatable results
• Instrument longevity

Frequently Asked Questions

Which measurement window should I use for soil testing?

For most soil testing applications, Kapton measurement windows are typically used due to their durability for field conditions. Prolene windows are generally selected only when improved light-element sensitivity or higher analytical sensitivity is required.

Can I switch between Kapton and Prolene windows?

Each SciAps X505 analyzer is calibrated for use with a specific measurement window type. You should only use the window material your instrument was calibrated for to ensure proper performance and accurate results.

What happens if I use the wrong window type?

Using a window type different from the one your analyzer was calibrated for can affect analytical performance and result accuracy. If you are unsure which window type your X505 is calibrated for, contact Alloy Geek before ordering.

How often should measurement windows be replaced?

Replacement frequency depends on sample type and field conditions. Soil, powders, and abrasive materials typically require more frequent window replacement.
