Description

The ZONESEMⅡ Tabletop Sample Cleaner uses UV-based cleaning technology to minimize or eliminate hydrocarbon contamination for electron microscopy imaging. Preparing, handling, or storing samples at atmospheric conditions may increase hydrocarbon build-up on the specimen, and under the influence of an electron beam these hydrocarbons can form a thick layer on the surface. Cleaning the sample surface with ZONESEMⅡ removes hydrocarbons and reduces available molecules for beam induced contamination. Preventing contamination from specimen surfaces is essential for true observation in electron microscopy. ZONESEMⅡ utilizes vacuum-controlled UV irradiation and activated oxygen to gently remove hydrocarbons from the specimen surface prior to imaging and without the use of any chemicals or reagents. With a lab-friendly footprint and intuitive touch screen, the second-generation ZONESEMⅡ is a safe, easy-to-use addition to any laboratory. 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. Cleaning Process The ZONESEMⅡ uses a UV lamp with wavelengths of 185 nm and 254 nm to efficiently remove hydrocarbons.
