![]() I had suspected that someone out there had come up with a home-spun way of doing this. And you drop from the syringe into a bottle so it ain't wasted.Ĭlick to expand.Dude, YOU are effing brilliant. My 50/50 was too thick to wick, and my dilution wasn't repeatable. Measure over a few ml and column pressure drop shouldn't matter between liquid as most are pretty close to the same density anyway. Should be laminar pipe flow by that time. Let the needle run for about 1ml then start timing. Without dilution the 50/50 (if PG Nic juice I cut with VG, and if VG Nic juice cut with PG) gives about 3 minutes per ml. I vape 50/50 juice (PG/VG) and cut it with 100 proof Vodka (water and ethanol, right?) to get between 1 minute and 1.5 minutes per ml drop time. ![]() A few different PG based Chinese Juices that also drop at about 1.5 minutes per ml.Ĭutting the PG and VG with distilled water at about 10%, 25%, 50% gives an exponential curve of decreasing drop times. I have some PG that may have absorbed some atmospheric water vapor that drops at about 1.5 minutes per ml. I run VG through it and the drop time is about 12 min/ml. I use a 10ml ink cartridge hypo with a rather LARGE blunt needle. I have a method I use that does not produce a real viscosity value, just a relative value that is repeatable.
