Thank you really much. This is a really professionall answere to my question. Thats what I wanted to hear. Now I am so angry about myself. Started yesterday with the Max Ion Tek and used tap water for boiling before the first freeze step. Now I will buy some destilled water asap.
The problem about heated naptha pulls or naptha here in generell is the good quality of the naptha.
Most of the teks here are written in the US. The German pharma naptha has such a low boiling point that it is a pain in the ass to work with. For example if you do warm pulls with eg. 50ml naptha you will loose it in less than 15 minutes...And you dont have a seperation layer anymore. If you close your extraction vessel with a lid the steams will build up a really high pressure after only 1 shake so that the glas or the lid could be able to burst. Thats why I always use big extraction vessels for laboratory use with a large volume like 5-6 L for just a few grams of bark. And pre evaping naptha before freeze preciepe takes only a few minutes of time. It happens really often to me that I go away for just a short time and when I come back I only have some goo in my evaping dish. This is really nasty... I know I could use lighter fluid but I dont want to... Not sure what is inside... I feel better with pharma solvents
Yes I know Xylene smells really terrible. Thats why I only use D-Limonene for "open" pulls for eg. when I am doing Q21 lime tek. But Xylene does not evap so fast than Naptha. You can easily give your mix a shake, go outside or to your window and release the pressure without any fear of exploding extraction vessel
When I do this with Naptha there is so much pressure / steam that I am even terrified about a burning light bulb or something else which could be enough for fire up the naptha air mix.
And yes Xylene pulls much more. I dont care about clean white crystals. This is exactly what I want. In my opinion using Naptha is a waste of some good DMT-material. Anyway... during the salting step for eg. using FASI / FASA you leave nearly 100% of the not wanted fats in the solvent
