Celda electroquímica 12852A.
The 12852A flat panel cell
for coated plates consists of a cylindrical cell body with an O-ring
grooved bottom edge for direct clamping to a flat sample having a 3"
(7.6 cm)
or a 4" (10.2 cm)
width dimension and any length of 3" or more. The counter electrode
is parallel to the surface of the sample to provide optimum current
distribution for EIS measurements. The reference electrode is mounted so
as to fit through an opening in the counter electrode.
The cell body rests on the sample and is pressure clamped to the sample
between the top and bottom plates with four threaded stainless rods. The four rod clamping approach improves the alignment of
the cell body and sample over other designs. The cell will accommodate
samples having a 3" width and a thickness of 1/16" or less to
3/8" (<1 to 10
mm). The top and bottom cell clamping plates are
fabricated from " acrylic for corrosion resistance. All cell
hardware is stainless steel. A neoprene sealing O-ring is supplied with
each cell.
The cell is furnished with a top bar having holes for the mounting of the
counter electrode and support of the reference electrode. The cell top is
otherwise open and accessible. The counter electrode is Pt on Nb expanded mesh. The CE height over the sample is
2".
The exposed area of the sample is 32 cm2 and the cell electrolyte
capacity is about 250 mL. The cell container
body is acrylic (polymethyl methacrylate),
which has excellent chemical resistance and good optical clarity for
observation of the contents of the cell.
