PAGE Rack
The rack serves three purposes:
1. It divides the tank into anodic and cathodic chambers and supports
and seals the gel cassettes vertically inside the separation tank with
rubber gaskets.
2. It holds the platinum wire electrodes that conduct the current
during electrophoresis.
3. Features in the base create the circulation pattern to maintain
constant temperature, and provide efficient cooling if the SE900 is
connected to a recirculating water bath.
The PAGE rack locates in four channels in the clear sides of the tank.
The PAGE rack has only one proper orientation. A cutout in the base
(Fig 6) aligns with a key in the separation tank. If the PAGE rack is
inserted incorrectly, the buffer circulation will not function properly,
and the safety lid will not fit.
The electrodes terminate at banana plugs that connect to the safety
lid (Fig 7).
Slots with rubber seals accept the gel cassettes and hold them verti-
cally in the separation tank. If one of the six positions is empty, the
rubber seals eliminate electrical leaks without the need for blank
cassettes or space fillers.
