Liquid Cell
Liquid Cell with Standard Sample Plate 191
Liquid Cell with MAC Mode 193
Flow-Through Liquid Cell 193
The liquid cell enables in-situ AFM or STM imaging for better control
under realistic environments. The cell is made from chemical-resistant
polycarbonate and can be used with a wide variety of liquids. The cell
can be used in conjunction with a standard, MAC Mode or temperature
control sample plates.
A flow-through version of the liquid cell is also available with 0.9 mm
holes included for tubing.
Eight-degree angle nose assemblies are recommended for imaging in
liquid because the smaller angle takes into account the different angle
the laser makes as it goes in and out of the fluid, compared to operation
in air.
Figure 125 shows the components of the liquid cell: two retaining clips,
an O-ring gasket and the liquid cell plate. Figure 126 shows the
components as assembled on a standard sample plate. Note that, when
assembled, the sample itself comprises the bottom of the liquid
CAUTION
Some nose assemblies, such as the two-piece nose assemblies, are not
sealed and should never be used for imaging in liquid. Be sure to use only
approved nose assemblies for imaging with the liquid cell.
