TEM Sample Preparation - Drop Casting

This video demonstrates how to prepare a powdered sample for transmission electron microscopy (TEM) analysis using the drop casting technique. Supplies you will need include: clean TEM mesh grid, TEM grid holder box, your sample in powdered form, glass vial, metal scoop/toothpick/glass rod, sharp tweezers, pipette, filter paper, and solvent of your choice (e.g., methanol, ethanol, isopropanol, DI water).
NOTE: If you will be making multiple samples, make sure to clean off your supplies (with a Kim wipe and methanol) and use a new pipette between samples in order to avoid cross contamination.

Great Sheri. I have done thousands of samples using JEM-2100F TEM.

which side of grid when you drop cast? shining or dull side? tq in advance

I drop on the darker side (the one with the C substrate).
