10.3.2 Larger Samples
For larger samples, it may be desirable to image a small region under a drop of fluid (see Figure
10.3a ).
1. Put the drop of fluid onto the sample.
2. Lower the AFM fluid tip holder into the drop.

10.3.3 Smaller Samples
Alternatively, it may be desirable to image smaller samples that are totally immersed in a liquid
bath.
1. Place the sample in a plastic petri dish.
Note: If you wish to construct a custom sample holder, please contact Veeco for more
information.
2. Secure the sample to the bottom of the petri dish lid or other sample holder with epoxy or
other non water-soluble adhesive.
Note: For non-critical applications, Devcon 2-Ton Epoxy works well. For
applications where contamination control is more critical, use a more inert,
solvent-free epoxy like Master Bond EP21LV, EP21AR, or a hot melt adhesive.
3. Follow the manufacturer's directions for mixing and curing to obtain the best resistance to
leaching and chemical attack. For lower resolution applications where it is desirable to image
a sample quickly without waiting for an adhesive to cure, you can use double-sided tape as
long as fluid never touches the tape.
Note: Do not use cyanoacrylate glue (like Super Glue) for mounting samples in fluid.
