“Guery” is a Level AFM under high vacuum. It includes a turbo molecular pump and an oil free pre-vacuum pump, that evacuate the vacuum bell jar within less than 10 minutes to a pressure of 3E-5 hPa (mbar).
The main application for this device is for samples,
which have been prepared in HV chambers and cannot be stored
under ambient pressure for a long time without changing their surface properties.
