There is forward momentum
Im doing pulls with heptane and its turning slightly yellow and cloudy.
From what ive read this is normal so i hope its going the right way
EDIT: I just took a look in the freezer and there seems to be crystals building in the heptane.
Will post back tomorrow with pics as well as a report on how much the yield was, Happy Dance
EDIT2: I thought it would be nice to include more info on what i did so here goes:
After the plant matter was separated from the acidic water by filtering through a tshirt and by squeezing it was boiled down to about a litre.
The litre was a bit much for the bottle i have so it was separated into two halves.
Water and lye were mixed in the bottle, then half of the acidic water was added and shaken to help with the bacification.
Then heptane was added and the bottle put into a double boiler to bring the temperature up.
I did three 30ml heptane pulls per half litre of MHRBwater and used a 10ml syringe to make sure none of the base got into the jar that is being used for the FP.
(and the rubber plunger expanded a bit in contact with the solvent as i had read it would, it got a bit stiff but luckily it didnt become unusable)
I figure there wont be a problem with using so much solvent as almost all of it can be recovered and reused.
