A Specimen Holder for Liquid Sample Analysis in TEM


K-kits are sample holders designed to facilitate convenient TEM observation of liquid samples, allowing nano-objects, aggregates, and agglomerates (NOAAs) in liquid samples to be characterized.


With vacuum compatible sealing of liquids in electron-transmitting thickness, K-kits are micro reaction chambers for countless experiments in materials, chemical, and biological research.


Features • Applicable for most TEM holder brands


• Strong structural reliability under vacuum • Sealing glue compatible to many solvents • Disposable • Free of cross-contamination • Easy to use
