About Vacuum Generators (VG)

Vacuum Generators was a UK-based company that became synonymous with high-quality UHV components and surface science instrumentation. Their products were widely used in:

• Surface science research (XPS, AES, SIMS, LEED)

• Molecular beam epitaxy (MBE) systems

• Electron microscopy and sample preparation

• Particle accelerator beamlines

• Semiconductor processing equipment

VG components are still highly regarded and compatible with modern UHV systems using ConFlat (CF)-type flanges .

CF Flange System

ConFlat (CF) flanges are the industry standard for UHV applications, featuring :

• Knife-edge sealing surface that embeds into a soft copper gasket

• All-metal seal for bakeable, leak-tight UHV performance

• Interchangeable across manufacturers following ISO 3669 standards

• Pressure ratings down to 1×10⁻¹³ mbar achievable

This chamber’s CF flanges ensure compatibility with a wide range of vacuum components, including pumps, gauges, viewports, and feedthroughs from various manufacturers.
