8-Inch Quartz Tube Specifications and Compatible Tools

Key specs: 200mm OD, 1,200mm length, 3–5mm wall thickness, 99.99% fused silica, max temp 1,200°C. Compatible with:

Lam Research Centura RTP (2010–2018)
Applied Materials 300mm furnace (model 5500, 2012–2020)
Tokyo Electron Lambda Twin-Star (2008–2015)
Exclusion: Avoid part #SG-QT-200-12 on Veeco Discovery tools (2003–2007) due to incompatible flange threading (ISO 9001 vs ASME B16.9). Verify O-ring groove dimensions before purchase.

What to Check Before Buying a Used 8-Inch Quartz Tube in 2026

Microcrack inspection: Use 5× magnifier; reject if >2 cracks/cm² are visible near the mid-length.
Thermal shock test: Heat to 1,000°C for 30 min, then quench in water. Measure warping with a dial gauge (<0.1mm deflection acceptable).
Wall thickness: Use digital micrometer at 4 points; deviation >0.5mm from spec indicates uneven erosion.
Purity verification: UV-Vis spectroscopy must show <5ppm OH⁻ contamination (peak at 2,730nm).
Lifecycle data: Reject tubes with >5 years in high-temp cycles (>800°C) without recertification. Request furnace logbooks showing max temp history.

FAQ

Q: Used vs refurbished quartz tube—what’s the difference?
A: Used parts are resold as-is; refurbished units undergo recertification (purity, structural integrity) and are warrantied for 6–12 months.

Q: How to test for quartz contamination?
A: UV-Vis spectroscopy identifies OH⁻ and metal impurities. Alternatively, perform a 10% HF etch test for surface pitting.

Q: Compatible with 300mm wafer processes?
A: Yes, but confirm the tube’s ID matches your tool’s susceptor dimensions. Most 8-inch tubes handle 200–300mm
