Sample Cleaner

ZONESEMⅡ

The ZONESEMⅡ Tabletop Sample Cleaner uses UV-based cleaning technology to minimize or eliminate hydrocarbon contamination for electron microscopy imaging.

ZONESEMⅡ Sample Cleaner

ZONESEMⅡ

Designed specifically for Hitachi specimen holders, the ZONESEMⅡ provides optimized sample cleaning and storage modes of operation. The ZONESEMⅡ serves as an excellent desiccator to prevent holder out-gassing.

Easy-to-use touchscreen panel
Programmable up to 24hrs
Variable pressure control

Cause of contamination

Interactions between hydrocarbons on the specimen surface and the irradiated electron beam generate sample contamination. Hydrocarbons are generally non-covalently attached to the specimen surface during sample handling, preparation, and storage.

Sample Cleaning Necessary

Cleaning Process

The ZONESEMⅡ uses a UV lamp with wavelengths of 185 nm and 254 nm to efficiently remove hydrocarbons. Ozone is generated from oxygen in the vacuum-controlled specimen chamber, and generated ozone is broken into oxygen and activated oxygen. Hydrocarbons on the specimen surface are broken into volatile molecules such as CO₂, H₂O by radical oxygen and UV. The exhaust pump evacuates the free molecules from the sample chamber.
