I was wondering about what types of solutions can be run through a flow
cytometer without causing damage or corrosion. Is pure ethanol okay? On
the advise of others, I have run 50% hot bleach to clear up clogs, but I
was very weary about doing this since bleach corrodes stainless steel.
I've always followed with a 5 minute water rinse, but this concentration of
bleach seems a bit extreme (we routinely use 10% bleach at room temp).
If 0.1% triton or 70% ethanol is as effective as 50% hot bleach, than this
seems to be the way to go. Any thoughts about this? What do
manufacturers recommend?
