If you use more non-polar, you have to pre-evap for better saturation - thus easier freeze-precipitation.
Do not use any filter if possible, just let it for a day in the freezer and then pour of the non-polar carefuly as fast as possible when out of the freezer.
Acceptance of the fact that our reality is not real doesn't in fact mean it is not real. It just leads to better understanding what real means.
