YM Technology designs and manufactures spherical vacuum chambers to meet the highest standards for industrial and research applications, suitable for both High Vacuum (HV) and Ultra-High Vacuum (UHV) environments.
Spherical vacuum chambers are commonly integrated into a variety of surface analysis instruments, supporting techniques such as X-ray Photoelectron Spectroscopy (XPS), Auger Electron Spectroscopy (AES), Contact Angle measurements, and Atomic Force Microscopy (AFM).
These chambers feature multiple access ports of varying sizes to accommodate connections to experimental devices, vacuum measurement gauges, electrical and motion feedthroughs, and analytical instrument accessories. With advanced machining and welding capabilities, YM Technology produces spherical chambers in sizes ranging from 8 inches to 20 inches or larger. All dimensions and tolerances are meticulously crafted to meet UHV standards and customer specifications.
Technical Parameters of Common Vacuum Chambers:
1. Material: 304 stainless steel, 316L stainless steel, or customer-specified materials.
2. Operating temperature range: -190°C to +1500°C (water cooling required for high temperatures).
3. Sealing method: Fluorine rubber "O" rings or oxygen-free copper metal seals.
Factory Testing Procedures:
1. Vacuum leak rate test: Standard leak rate: 1.3×10⁻⁸ Pa·L/s.
2. Water cooling pressure test: Standard test pressure: 11.6psi, 24hour leak-free test.
Surface Treatments:
- Electropolishing
- Sandblasting
- Acid cleaning
- Mirror polishing.
If you need to order our vacuum chambers, please contact our professional sales team and provide the following information:
1. Whether the product generates heat during use, the specific high and low temperatures, and whether water or liquid nitrogen cooling is required.
