Guide of Using EASY SCAN STM
2. Tip Preparation
A. Using ethanol, cleaning Ir/Pt wire & other tools. This step isn`t necessary, but may help if you are having problems obtaining a good image.
B. You`ll then cut a piece of wire that is about 5mm to 10mm long. Make sure you don`t lose it!!
C. Still holding this piece of wire with the pliers, place the cutters at the free end, as obliquely as possible (see picture)
D. Close the cutter until you can feel the wire, then in the direction shown below, pull and cut at the same time, The tip needs to be torn off rather than cleanly cut off in order to get the required point.
E. Hold the wire with the tweezers behind the freshly cut tip.
F. Insert it carefully under the golden tip holders in the scan head without twisting them
Important
A. Never touch the tip end with anything
B. The golden tip holder in the open part of the scan head are very delicate and not to be twisted
