this is the reason that dual scrubbers have an advantage: you can use up scrubber 1 almost for 100%, withouth big safety issues, because there is still scrubber nr 2
I also notice that the purple is far less clear in the axial than in the radial scrubber: must have to do with the 'heat-keeping' properties of the radial
what the pictures show: well at least that scrubber 2 is still active :-) (as I continued using it as primary scrubber for the next 3.5 hours, till end of the trip) (after that, I binned it: purple around central tube for +/- 2 cm) (I also binned the second scrubber then: there was not one purple grain in it: this means that the first one (in the 3.5hour test) (that is the second one in the 9.5 hour test) was stil active!

Paul;
Are the two scrubbers inter-changeable? (Can you throw out the used sorb from the upstream can, put the downstream can in the upstream position and put the newly re-filled can in the downstream position?)
If so, could be a nice way to more safely be efficient with sorb.
