Chapter 3: Using BD FACSDiva Software 101
Sort Setup
Sort setup values for four different nozzle sizes can be downloaded using the Sort
> Sort Setup command. Default settings are provided for each sorting option,
along with a custom setting for each option.
As a general rule, for optimal results when sorting large or fragile cells, use a
larger nozzle size and lower pressure. To increase throughput and yield when
sorting smaller or less fragile cells, use a smaller nozzle size and higher pressure.
If you make changes to any of the settings, the changes are automatically saved
when you exit BD FACSDiva software or when you switch to a different sort
setup mode. When you restart, the most recently used set of values is restored.
Default settings are shown in Table 3-2 on page 102.
In addition, the sort setup menu has following menu items: 70 Custom, 85
Custom, 100 Custom and 130 Custom. Initially, all of these new setups are exact
copies of the corresponding original setups with the same defaults. This allows
you to create two sets of sort values (pressure, for example) for the same nozzle
size.
Sort Setup
name
Nozzle
(microns)
Default pressure (psi)
70 micron 70 70
85 micron 85 45
100 micron 100 20
130 micron 130 10
Do not use a nozzle size that is different from the sort setup setting. The gap
values and sensitivity algorithms are optimized for particular nozzles and
are not suitable for other nozzle sizes. The system performance could be
unstable.
