I too have been concerned about making aerosols of infectious agents
through droplet sorting. In a recent posting it was noted that the
ELITE has an exhaust fan that draws through a biohazard filter. I
recently checked to see if the fan was actually drawing air through
the filter. I placed a smoking Q-tip in the sort chamber and closed
the plexiglass door. The smoke filled the chamber with air currents
insufficient to show any clearing of the smoke. If I held the Q-tip
close to the exhaust port the smoke was dawn slowly towards the port.
If I removed the biohazard filter, the smoke was drawn from the
chamber much quicker.
I am left with a "catch-22". The fan will draw droplets out the back
of the instrument only if there is no filter to catch the infectious
agents.
