I have one of those green mastercool #15 tanks I got from bvv. It does have a diptube in it, but it’s leaving about 1-2lbs of butane in it once I open it up to the column. I understand the dip tube doesn’t go down all the way and that’s why I’m having butane left in my tank.
My question is. How should I go about getting that last bit out? I’m used to vac’ing down my solvent tank before I recover to it. Makes it a little bit tough with that butane left over in the tank.
Since it’s a small tank should I just hook up to the vapor port and flip the tank over instead of using the dip tube?
What do you guys recommend?
Thanks for any help you can give. Appreciate it.
