The Au-Flat TEM Grid features a precise 1.2 µm and 1.3 µm hole pattern on a robust 300 gold mesh, making it an essential component for high-resolution cryo-electron microscopy (cryo-EM) sample preparation. Crafted from high-quality gold, this grid offers excellent conductivity and stability, which are critical for optimal imaging performance and minimizing sample drift in cryogenic environments. The uniform hole pattern facilitates consistent ice thickness and particle distribution, crucial for achieving high-quality data. Designed for reliability and ease of handling, these grids support a streamlined workflow for vitrification and subsequent imaging. They provide a stable and optically clear substrate for delicate biological specimens, contributing to enhanced resolution and reproducibility in structural biology research. This product is supplied in a convenient box of 5 grids, ensuring a ready supply for demanding experimental needs in cryo-EM.
