Heating, annealing, degassing, and sample preparation are essential processes in many ultra-high vacuum (UHV) applications. Selecting the appropriate heating technology is critical for achieving reliable temperature control, minimizing contamination, and ensuring reproducible experimental results.
UHV Store offers three proven heating technologies to cover a wide range of research and industrial applications:
PBN/PG Heating – Clean, highly stable radiative heating up to approximately 1000 °C. Pyrolytic Boron Nitride (PBN) and Pyrolytic Graphite (PG) heaters provide excellent temperature uniformity, low outgassing, and outstanding chemical purity, making them ideal for UHV, MBE, thin-film deposition, and sensitive surface science applications.
Direct Current (DC) Heating – Efficient resistive heating of conductive samples by passing electrical current directly through the sample or sample holder. This method enables rapid heating and cooling cycles and temperatures of up to approximately 1300 °C, making it well suited for annealing, cleaning, and routine sample preparation.
Electron Beam (E-Beam) Heating – High-performance, non-contact heating for refractory materials and applications requiring extreme temperatures. Electron beam heating can achieve temperatures of up to approximately 2000 °C while minimizing thermal load on surrounding components, making it ideal for demanding UHV research and materials science applications.
The maximum achievable temperature depends on factors such as sample geometry, material properties, thermal shielding, mounting configuration, and the overall vacuum system design.
