In Transmission Electron Microscopy (TEM) experiments, the selection of support films on grids directly affects imaging quality and experimental accuracy. As commonly used laboratory consumables, ZJ series TEM copper grids are widely preferred due to their stable material quality and precise specifications.
This article provides a comprehensive overview of the ZJ TEM copper grid product line, covering structure, specifications, and application scenarios, helping you quickly identify the most suitable option for your experiments and avoid common selection mistakes.
This product line is supplied by SCI Materials Hub, a professional scientific materials provider offering reliable sourcing, customization services, technical support, and stable inventory. It supports both small-scale research procurement and pilot-scale production, serving universities, research institutes, and enterprises worldwide.
ZJ TEM copper grids are divided into five main categories:
⚡ ZJ Ultra-Thin Carbon Film
🧱 ZJ Standard Carbon Film (Regular Carbon Film)
🧫 ZJ Holey Carbon Support Film (Conventional Microgrid)
🧬 ZJ Small-Hole Microgrid Carbon Support Film
⚙️ ZJ Thin Carbon Film
Each category is designed for specific experimental needs, with differences in structure, specifications, and application scenarios.
The ultra-thin carbon film adopts a three-layer structure, where an additional ultra-thin carbon layer is deposited on a microgrid support film.
Unlike pure carbon films supported only by grid holes, this ultra-thin layer (<5 nm) is one of the thinnest available support films, specifically designed for well-dispersed nanomaterials.
This structure enables uniform sample distribution and is ideal for:
🧬 1D nanomaterials (nanowires, nanotubes)
🔬 Low-contrast, small-size nanocrystals
