Uncoated Wide-Rim Hexagonal Mesh Copper TEM Grids

Uncoated copper TEM grids with a hexagonal mesh pattern, also described as round-hole grids, a 3 mm outer diameter and a wide 350 um rim, made by etching. No support film is included. The grid is used to hold thin sections, particles or films that you prepare yourself, and a film can be added for imaging dispersed nanomaterials. Eight mesh sizes are available: 50, 75, 100, 150, 200, 230, 300 and 400. Pitch, bar width and hole size in um: 50 mesh 580, 80 and 500; 75 mesh 405, 55 and 350; 100 mesh 280, 30 and 250; 150 mesh 180, 30 and 150; 200 mesh 140, 20 and 120; 230 mesh 119, 19 and 100; 300 mesh 90, 15 and 75; 400 mesh 75, 10 and 65. A higher mesh number gives smaller openings and more bar area, with a smaller viewing area. Each bottle contains 100 grids.
