Unpacking and inventory
Unwrap all packages carefully and compare con-
tents with the packing list, making sure all items
arrived. If any part is missing, contact your local
sales office. Inspect all components for damage
that may have occurred while the unit was in
transit. If any part appears damaged, contact the
carrier immediately. Be sure to keep all packing
material for damage claims or to use should it
become necessary to return the unit.
Lower buffer chamber
The lower buffer chamber is transparent acrylic,
which allows visual tracking of electrophoresis
progress. The chamber is chemically resistant to
common electrophoretic buffers but not to organic
solvents or strong acids and alkali. Temperatures
above 45 °C may cause the chamber to warp.
Upper buffer chamber
The upper buffer chamber is molded polysul-
fone, which is chemically resistant to common
electrophoretic buffers but not to organic sol-
vents or strong acids and alkali. The upper elec-
trode (cathode) runs along the center ridge, and
terminates at a banana plug. The lower electrode
(anode) runs along the edge of the electrode fin
on the underside, and terminates at a second
banana plug.
Safety lid
The banana plug on the upper buffer chamber
at the terminus of the cathode wire connects to
the black lead. The banana plug on the lower
electrode fin at the terminus of the anode wire
connects to the red lead. The 4-mm shrouded
color-coded leads plug into color-coded jacks in
the power supply. Always install the safety lid
before use!
Note: Before using the first
time, disassemble the unit and
wash with a dilute solution of a
laboratory detergent and rinse
thoroughly first with water and
then with distilled water.
