2. 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

3. 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.

4. TEM Grid Preparation Hold the grid with tweezers.
Do not touch/contaminate the grid.
Do not bend the grid.

5. TEM GRID PREPARATION
Take a micropipette and put a droplet on top the grid. Let the solution sit on the grid.
After 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.
