Transferring Filter Modules to an alternative housing
If sample filtration was performed in a housing other than one suitable for use with the Pressure
Elution Station, you must transfer the Filter Module to an appropriate housing before elution.
1. Remove the lid of the housing used for sampling or the transport container, and carefully
transfer the Filter Module, bolt-head down, to a Filta-Max
xpress
Filter Housing, which will be
used in the Pressure Elution Station.
2. Pour any remaining liquid from the Filter Housing or container into the centrifuge tube.
3. Rinse the Filter Housing or container with reagent-grade water, and transfer this rinse to the
centrifuge tube. The total volume transferred to the centrifuge tube should not exceed
50 mL.
4. Seal the second housing as described in
"Assembling the Filter Module and filtering the
Understanding the control panel
Instruments with a
four-button
control panel:
The menu screen displays the following:
•
F1
starts the elution cycle.
•
F2
checks the pressure.
With the buffer reservoir cap sealed, press and hold the
F2
button for 3 or more seconds.
Listen for any air leaks, and monitor the low-pressure gauge for pressure changes.
•
F3
resets the cycle counter.
Press and hold the
F3
button for 3 seconds to display the number of cycles completed (i.e.,
the number of samples eluted).
Press and hold the
F3
button for 5 seconds to reset the counter to zero.
•
F3

F4
display total cycles run (this counter is not resettable).
Press and hold the
F4
button, and then press and hold the
F3
button to display the total
number of cycles run on the Pressure Elution Station.

Note:
A Filter Housing without a Filter Module must be in place.
A centrifuge tube must be in the centrifuge tube holder.
The buffer reservoir must be empty.
The buffer reservoir cap must be securely sealed.
