The LKB Nova Ultramicrotome is a precision instrument used for preparing ultra-thin sections of soft materials, typically ranging from 50-70 nm in thickness, using a diamond knife. This makes it ideal for preparing TEM/STEM (Transmission Electron Microscopy/Scanning Transmission Electron Microscopy) lamella of polymers or biological materials. Ultramicrotomes are essential tools for high-resolution imaging, producing sections typically between 20 and 150 nanometers thick, allowing for detailed visualization of internal structures at nanometer scale resolution. While this model does not offer a cryo option, it is highly versatile and can be used for a wide range of materials, including biological specimens, polymers, metals, and ceramics. The ultramicrotomy process is known for being relatively fast and efficient, yielding clean sections with minimal artifacts, which is crucial for high-quality TEM sample preparation.
