The larger pins are for connection to the safety lid and complete the
electrical circuit when the lid is in position.
The small left land pin is used to connect the EPH/IEF or card-mounted
cathode electrodes. The small pin on the right connects to the card-mounted
anode or the EPH/IEF cathode via the red lead mounted on the unit.
The buffer tank holds the four adjustable levelling feet, supports the cooling
plate and is covered during electrophoresis with the safety lid.
The buffer tank includes four buffer chambers, each with a 1 liter capacity,
allowing the user to choose one of two orientations for electrophoretic runs.
The safety lid contains electrode leads, apertures for voltage measurement,
and a safety interlock.
The well-recessed cathode connector (black) and anode connector (red) for
connection to power supplies ensure safe operation at high voltages.
The polycarbonate lid snugly fits the contours of the buffer tank. This makes
it possible to reduce the atmospheric CO
for IEF at basic pH intervals) and provides increased protection against
condensation.
Note: Polycarbonate is not resistant to concentrated acids and
bases, or to halogenated and aromatic hydrocarbons.
