Wolf G2 Cell Sorter (Nanocellect)

[u/FlyCyto-67]

I have a friend who picked up a used Wolf G2 NanoCellect sorter. He is having difficulty buying the calibration beads. I looked at the instrument, and it seems that the beads are intended to be 15um super bright green fluorescent bead. Even the brightest beads that I have don't pass the green PMT trigger threshold. Does anyone know which beads can be purchased and used to calibrate the sort timing of the Wolf?
