Environmental chamber
The environmental chamber includes eight ports which may be used to
introduce or remove gases from the chamber, or to allow wiring access
for sensors or other electronics. Several types of screw-in fittings are
available from Keysight for wires, liquids or 3 mm (1/8 in) inner
diameter gas tubing. The ports can be used in any combination. For
example, one gas port may be used to introduce a gas while another
simultaneously vents the chamber (i.e., when the gas cannot be safely
vented directly into the lab). One such example would be a non-aqueous
electrochemistry experiment requiring the saturation of an inert as with
an organic solvent.
To use the chamber:
1
Prepare the sample on a sample plate.
2
Mount the sample plate on the microscope.
3
Loosen the retaining screws on the front right and left corners of the
microscope base and swing the top section up on its hinge.
4
Lower the microscope base over the environmental chamber, being
careful to avoid contact with the sample plate. The legs of the
microscope base will fit into grooves in the environmental chamber
base.
