BLACK & WHITE TUBE PHOSPHOR APPLICATION (ii)

Just in case you thought Sebastian and his co-workers had to heft these long and wieldy tubes to remove the supernate, actually, no, they were placed on a rotating carrel that was tilted at such a rate as not to disturb the accreted phosophor film that sat on the inner face of the tube.  Here you see a laboratory coating system, however, the full size plant used a similar principle  - such fun!
