Eluting the sample
1. Turn on the Pressure Elution Station by depressing the on/off switch to the
I
position. The
green LED (power) and the red LED (machine ready) are lit.
The on/off switch is located on the back of the Pressure Elution Station.
2. Remove the lid from a 500 mL centrifuge tube, and place it into the collection vessel holder.
3. With the Filter Housing QF stem facing upward, attach the outlet diverter fitting to the QF stem
by pulling back the collar and pushing the fittings together.
4. Turn the Filter Housing over, and place the outlet diverter over the centrifuge tube to catch any
sample that may leak.
5. Connect the Filter Housing QC body to the QC stem on the Pressure Elution Station by
pushing the fittings together.
Note:
If you have already performed a system check, you can skip steps 6–7 and proceed
directly to step 8.
6. Check that the air supply is set up correctly, the air line is connected to the Pressure Elution
Station, and the air inlet valve is open.
Note:
Compressed air must be used with the Pressure Elution Station.
7. Ensure that there is sufficient buffer solution in the buffer reservoir bottle and that the seal
between the closure cap and the reservoir bottle is airtight.
8. To start the filter elution cycle:
On the
four-button
control panel
press
F1
.
On the
touch-screen
control panel
press
Start
.
IMPORTANT:
During the elution cycle, the collection vessel holder and centrifuge tube are
lifted into position. Do not override the door sensors as they protect you from pinch points
produced by this movement. If the door sensors fail to function, do not place your hands or
any objects in this area. Contact IDEXX Technical Service for assistance.
9. At the end of the elution cycle, disconnect the Filter Housing from the Pressure Elution Station
by pushing the collar on the QC body upwards while pulling the Filter Housing down; then
disconnect the outlet diverter fitting from the Filter Housing.
