Custom Stainless Steel Vacuum Chambers

Precision-Engineered for Demanding Vacuum Applications

With nearly 20 years of expertise in vacuum equipment manufacturing, we deliver high-quality, custom-engineered stainless steel vacuum chambers built to meet your exact specifications. From R&D labs to large-scale industrial production, our chambers provide reliable performance, exceptional durability, and outstanding vacuum integrity.

Why Choose Our Custom Vacuum Chambers?

Tailored to Your Needs
No two applications are the same. We offer flexible customization – including size, shape, port configuration, material grade, surface finish, and accessories – to perfectly match your process requirements.

 20 Years of Vacuum Experience
Our long-standing track record means you benefit from mature manufacturing processes, rigorous quality control, and deep technical knowledge. Every chamber is backed by two decades of real-world application engineering.

 Premium Stainless Steel Construction
Made from high-grade SS304 or SS316/316L, our chambers offer excellent corrosion resistance, low outgassing, and high strength. Ideal for high-vacuum and ultra-high-vacuum (UHV) environments.

 High Vacuum Performance
Achieve vacuum levels down to 10⁻⁷ mbar (or lower depending on configuration) with leak rates ≤ 1.3×10⁻⁷ Pa·m³/s – thanks to precision welding, smooth internal finishes, and careful material selection.

 Certified Quality
Each chamber undergoes helium leak testing, pressure testing, and surface inspection.
