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 TEM sample plasma cleaners/plasma ashers are fully automated and come with standard adapters suitable for the sample holders supplied with all the major microscope manufacturers.
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.
Additionally, we offer an optional TEM holder vacuum storage manifold, capable of holding up to three sample holders (extendable to 5). It includes blanking plugs to seal individual sample holder chambers when not in use.
The TEM plasma cleaner/plasma asher is an application-specific solution for low-pressure plasma cleaning and preparation of electron microscopy samples including:
- Plasma cleaning
- Low power operation
- Front feed of TEM sample holder
- Integral TEm holder vacuum storage manifold
- Multiple TEM grids and SEM stub cleaning
- Re-entrant style sample holder introduction
- Dual gas inlets for O2/Ar and other gases
- Recipe store and recall
