The Hitachi SU3500 is a premium variable-pressure scanning electron microscope (VP-SEM) designed to deliver high-resolution imaging across the full range of sample types — from conductive metals to uncoated biological specimens, ceramics, polymers and paper — without the need for conductive coating. Its newly designed low-aberration objective lens and hex bias technology achieve 7 nm SE resolution at 3 kV and 10 nm BSE resolution at 5 kV. The large specimen chamber accommodates samples up to 200 mm diameter, 80 mm height and 8 kg weight, with a 5-axis eucentric motorised stage. Variable pressure mode (6–650 Pa) enables imaging of hydrated, outgassing and non-conductive samples.
