High-quality SEM and TEM imaging is frequently hampered by hydrocarbon contamination. These carbon-based residues, which can be added during sample preparation or accumulated during imaging, can obscure smaller features, skew data, and are time consuming to correct.
This contamination can be safely and effectively removed without chemicals at the lab bench using the Hitachi ZoneSEM II and ZoneTEM II UV-based Sample Cleaners. These small devices use activated oxygen and low-energy UV light to gently clean the samples without causing surface changes or breaking delicate structures.

Features and Benefits
Gentle, Chemical-Free Cleaning
The ZoneSEM II and ZoneTEM II cleaners use UV lamps to break down hydrocarbon bonds. In the presence of oxygen, the UV light triggers the production of ozone and reactive oxygen species that oxidize the hydrocarbons into volatile compounds like CO2 and H2O. This process safely removes contaminants without needing solvents, reagents, or external gas supplies.

Vacuum-Controlled Process for Sample Safety
The integrated pump's adjustable vacuum gives users precise control over the cleaning intensity, allowing them to optimize the process for their specific sample.

Easy to Use, Easy to Repeat
A user-friendly touchscreen interface makes it simple to select and run cleaning protocols. Recipe memory allows users to save and recall process settings, which is ideal for labs with multiple users or routine workflows.

Cleaning and Storage in One
The ZoneSEM II and ZoneTEM II serve as both sample cleaners and storage units. This helps prevent re-contamination and minimizes sample outgassing before imaging. The ZoneSEM II is specifically designed to work with Hitachi holders.
