LAST???? Has anybody tried this?

Detlof and others- Not only is the trifluoro-trichloro-ethyl(e?)ne harmful the to ozone (altho the amount used is very small), it also is harmful to groundwater if you have a septic system/well. You wouldn't want to spill it on the ground or have it go down the drain.

Depending upon the cantilever size, this "siphoning" effect (technically known as capillarity) is a real physical phenomenon, relating to the surface tension of the fluid vs. the tube size. I do not know if this will cause a problem with these products attacking the cartridge, but small diameter tubes (capillaries) will definately draw a liquid up them (sorry, its too late to figure out a better way to write that sentence). You don't see it much in a straw due to its large diameter, but it can be significant for small diameter tubes.
