SEM Preparation Procedure

1. Stick carbon tape to stub.
2. Minimize samples; Mammillaria seilmanniana, zygocactus, and Hemerocallis. 
3. Stick the 3 samples to tub, use tweezers to divide tape into 3 sections, creating fiduciary lines.
4. Check if samples are stuck to the sub by using canned air; stand 1 foot away and spray air onto stub, so loose ends fly off. 
5. Use side notch of SEM and click 4 times to the right.
6. Place cup with samples into slot, and push down until green light turns on.
