Pfeiffer Vacuum

Customized Vacuum Chambers

Our many years of experience have ensured that we are familiar with almost all specific applications, and we can offer you detailed advice on system specification, design and engineering.
Our scope of work caters for your requirements: our first step towards the finished product involves producing an idea outline and a complete set of drawings.

In standard chambers we use stainless steel 1.4301/304 for pipes, chamber walls and ISO flanges, and 1.4307/304L for CF flanges. All possible austenitic stainless steels and aluminum alloys can be used as other chamber materials. For very low outgassing rates and high strengths after vacuum annealing above 950°C, premium stainless steel 1.4429 ESU/316LN ESR is available. We can provide 3.1 certification for materials upon request.

Our standard interior and exterior treatment is glass bead blasted. Surfaces can also be sanded, sanded and electro-polished, chemically stained and passivated, as well as vacuum annealed.
