Agilent’s VacIon Plus pumps are available with Diode, Noble Diode, and StarCell elements for various nitrogen pumping speeds. Diode Vaclon Plus pumps are regularly used in general purpose ultra high vacuum (UHV) systems for evacuating electron devices, and in sensitive electron microscopes. Noble Diode Vaclon Plus pumps are used in UHV applications when a gas mixture is being pumped at constant pressure making it ideal to obtain UHV pressures in particle accelerators, synchrotron rings, and surface analysis applications. The StarCell’s patented design makes this the only ion pump that handles high amounts of noble gases and hydrogen. It also provides the highest speed and capacity for methane, argon, and helium. The StarCell Vaclon Plus is ideal for applications requiring constant operation at 10-8 mbar or above.
