Ultra High Vacuum Cryostats

Ultra High Vacuum (UHV) cryostats by ARS are designed to meet the stringent requirements of surface science, space simulation, quantum materials research, and advanced microscopy. The UHV modification is typically applied to the instrumentation skirt of the cryocooler, allowing for installation in any orientation. To enhance functionality, translators, rotators, custom thermal shields, and extensions can be pre-installed to support a wide range of research applications.

Models:

• B True HV Variants – ARS cryostats feature a fully-welded flange (Conflat, ISO-F, ISO-K, ISO-KF, or custom), achieving a True-UHV rating of 10⁻¹¹ mbar.
• X-20 B ULV Variants – For applications demanding ultra-low vibration, UHV-compatible cryostats with specialized vibration isolation are available. These designs not only minimize mechanical noise but also allow the cryocooler to be easily detached without breaking vacuum, enabling chamber bakeout up to 200°C, a crucial feature for maintaining pristine experimental conditions.
