Standard copper TEM support grids from EMS (Electron Microscopy Sciences), for TEM sample preparation: G150 square mesh, FCF150 / FCF300 circular openings, 100 per pack.
EMS TEM copper grids are a basic consumable for TEM sample preparation, made of pure copper in several mesh types: G150-CU (square mesh, 150 mesh), FCF150-CU (Flat Carbon Film, circular, 150 mesh) and FCF300-CU (circular, 300 mesh). Standard 3.05 mm diameter for TEM sample holders, 100 per pack.

| FCF150-CU | Circular Flat Carbon Film | 150 mesh | Copper | 100 per pack |
| FCF300-CU | Circular Flat Carbon Film | 300 mesh | Copper | 100 per pack |
Outer diameter: 3.05 mm (standard TEM size).
How to choose TEM copper grids
Two main factors: opening type and mesh count (opening density).
| Factor | G150 (square) | FCF150 (circular 150) | FCF300 (circular 300) |
|---|---|---|---|
| Opening density | Sparse (large openings) | Medium | Dense (small openings) |
| Samples | Large particles, loose powders, fibers | Nanoparticles, thin films | Very fine nanoparticles |
| Sample support area | Large | Medium | Small (more support bars) |
📌 About FCF grids: FCF (Flat Carbon Film) grids have a very thin pre-applied carbon film on the surface, giving even sample support and reducing sample bending at the edges of openings — especially useful for observing dispersed nanoparticles. For versions without carbon film, please ask separately.
