How do they look under microscope? Square Grid Hexagonal Grid • 200 mesh • 55% open area, • 28 µm bar width • Thick:17.8 µm 3 mm
TEM Grid Preparation • There are two sides in carbon coated ultra-thin grid • Formvar side - lighter side (less hydrophobic than the carbon film) • Carbon film is on the darker side.
TEM Grid Preparation • Hold the grid with tweezers. • Do not touch/contaminate the grid. • Do not bend the grid.
TEM GRID PREPARATION • Take a micropipette and put a droplet on top the grid. Let the solution sit on the grid. • After 10-12 min, wick away the rest of the solution with filter paper. Do not touch the grid! • Finally let it sit until the grid dries off.
