Starting and Monitoring the Sort
1 Open the sort collection chamber door and install the collection tubes,
plate, or slide.
2 Install the sample tube onto the loading port and click Load.
3 Adjust the required flow rate, if necessary.
Typically, flow rates less than 6 give the best sorting results.
4 (Optional) Turn on the deflection plates and open the aspirator drawer.
The deflection plates turn off automatically each time a tube is unloaded. If
you do not turn them back on before beginning a sort, a dialog box appears
where you can turn on the plates and open the aspirator drawer by clicking
OK.
