S3 Cell Sorter Instruction Manual | 63
In front of each PMT is a holder for a neutral density filter or bandpass filter. Each filter holder
contains a screw-in retaining ring that can be removed or replaced with the provided red S3
spanner wrench.
5.4.2 Optical Filter Blocks
The S3 system includes two preset filter blocks. The filter set depends on the instrument
configuration. The optical filter blocks can be changed to accommodate dectection of different
fluorophores. These blocks can be easily removed with the silver handle (Figure 69).
The filter blocks contain the dichroic and bandpass filters. The optical filters within the block
are user changeable and will accommodate multiple filter sizes as described in Table 23. The
dichroic filter holders are locked from the bottom of the block. Once unlocked, they can be
removed and replaced from the top of the block.
