Storing the Pressure Elution Station
If the Pressure Elution Station will not be in use for longer than a week, store the unit appropriately,
following the guidelines below, to ensure that the unit remains fully functional.
1. Purge the unit of buffer by running two complete elution cycles using reagent-grade water.
2. Drain the blue liquid feed line as follows.
Instruments with a four-button control panel:
A Filter Housing containing a Filter Module, an outlet diverter fitting, and a centrifuge tube
must be in place before you begin.
a. Remove the closure cap from the buffer reservoir, and then remove the silicon tube
section that holds the tube weight.
b. Ensure the buffer bottle is 3/4 full.
c. Replace the closure cap.
d. Start an elution cycle, and allow the first two cycles to complete.
Some instruments may display a High Flow error. This happens when the water in
the lines has been replaced with air. Press the emergency stop button to reset the
instrument. The purging (draining) process is now complete.
e. Press the emergency stop button to halt the elution cycle process.
f. Air dry the closure cap, feed lines, and silicon tubing before storage.
Note: Do not detach the closure cap from the air and blue liquid feed lines.
Instruments with a touch-screen control panel:
A Filter Housing without a Filter Module, an outlet diverter fitting, and a collection vessel must
be in place before you begin.
a. Detach the closure cap from the buffer reservoir.
b. Empty the reagent-grade water from the buffer reservoir.
c. Replace the closure cap.
d. Press the Pressure Test button on the control panel.
e. Press and hold the Line Purge button until all the fluid is purged from the line. This
usually takes about 10 seconds.
Note: Pressing the Line Purge button will lift the centrifuge tube and purge the fluid from
the lines.
f. Press Exit to return to the start screen, and then remove the centrifuge tube.
g. Dry the liquid feed tube and closure cap..
Note: Do not detach the closure cap from the air and blue liquid feed lines.
3. Clean the pressure chamber as follows:
a. Remove the pressure chamber lid.
b. Dry the inside of the chamber using paper towels.
c. Clean the inside of the pressure chamber using absolute ethanol, and allow the
chamber to air dry.
d. Replace the pressure chamber lid.
4. Detach the Filter Housing and the diverter fitting, and remove the centrifuge tube.
5. Clean the inside of the unit following the procedure in “Maintenance and cleaning.”
6. Detach the air supply.
