hi Ged - re weight I'm pretty sure we are talking of grammes - I did actually buy one some years ago (never used though) as it was (then) so cheap but now can't find it
Nice find Chris, and not as expensive as sometimes things in this, er, neck of the woods can be. Any idea what it weighs?
Something like that could be handy if, say, you're very short of fuel. If not, I think I'd still opt for ten minutes at a rolling boil, just to be on the safe side.
Nylon line is not so good when using a fire because it can/will melt. I intended to replace the line with metal wire but could not find any suitable. (I tried stripping a single cable that had lots of thinner wire in it but the individual wires kept snapping - so if anyone has any good ideas on how to find some wire about one foot long and the thickness of fishing line please let me know)

It depends on the chemical - some will evaporate before the water, so you would end up concentrating them!
Boiling for a bit, then distilling would seem to be the way forward. The initial boiling drives off the low-boiling temp chemicals.
