10.5 Operating Principles

10.5.1 Clean Fluid Cell and Protective Skirt

To reduce contamination problems and to obtain high quality images, clean the ﬂuid cell and

protective skirt as follows:

1. When sample imaging is complete, carefully remove the protective skirt and fluid tip holder.

2. Place the fluid cell and protective skirt in warm, soapy water and place a few drops of liquid

dish soap on them.

3. Gently rub the fluid cell and protective skirt with a cotton swab or finger.

4. Using distilled water, rinse the fluid cell and protective skirt completely.

5. Using filtered, compressed air or dry nitrogen, blow dry the fluid cell until all moisture

evaporates to prevent the buildup of salts or other contaminants on the parts.

10.5.2 Select Mode of Operation

Select Microscope > Proﬁle and choose the proﬁle for either Contact Mode or TappingMode.

Click Load.

10.5.3 Load the Probe

The probe is held in a small pocket on the bottom side of the tip holder by a gold-plated stainless

steel wire. The cantilever installation ﬁxture has three docking stations where different tip holders

may be mounted. Use the docking station that has a small wire between two of the sockets. The

steel wire is held against the cantilever substrate by a leaf spring mounted on the top of the tip

holder.

1. To mount a probe in the holder, turn the holder over so that the leaf spring and four sockets

are facing down and plug the holder onto the appropriate docking station of the cantilever

installation fixture.

2. Grip the tip holder by the edges and gently push down on the holder.

CAUTION: Avoid scratching the glass surface with abrasive material.
