Henniker specialises in advanced, compact plasma cleaners that deliver precision surface cleaning for electron microscopy applications, ensuring reduced contamination and sharper, more reliable results.
Our versatile systems are compatible with major TEM and SEM sample holders, offering fully automated control and gentle, low-power operation. Experience increased measurement stability, minimised common sources of error, and simplified sample preparation backed by robust, user-friendly technology that adapts to your research needs.

The HPT-100 plasma cleaner for TEM, SEM sample & specimen holders is designed specifically for controlled and repeatable cleaning.
A compact, benchtop format, the HPT-100 is a fully automated, programmable device with standard adapters suitable for TEM specimen holders from all the major microscope manufacturers. The plasma output power is fully variable over the range 0-l00W (0-200W option), allowing gentle cleaning that can handle both ultra-thin carbon and graphene grids as well as bulk carbon deposition removal after STEM imaging.
