Pull with the heavy naphtha (100-140), re-x with the light naphtha (60-95)

i.e., buy both!

(Interested to know what shop that is...)

In my most humble opinion, heavier (but still aromatics-free) naphtha has shown itself to be advantageous to use when pulling from warm base soup with a view to freeze precipitation. For one thing, it evaporates more slowly which could be considered a positive if evaporation is not part of your plan. It does mean that recrystallisation from a lower-boiling solvent is preferable, however.

I think the temperature/solubility gradient is more favourable with a heavier naphtha although that's only my anecdotal word.

I've been getting a consistent low yield on every extraction attempt, first pull always yields 250mg and the second usually 50mg or less (from 50g of MHRB). So far I've tried about 3 different A/B teks with 2 different root bark sources, both shredded and powdered and yet I still get the exact same yields. Only thing I haven't changed in each extraction attempt is the solvent, which has this composition:
[CAS 110-54-3] n-Hexane ≥25% - <50%
[CAS 142-82-5] Heptane ≥25% - <50%
[CAS 64742-89-8] Low boiling point solvent naphtha ≥10% - <25%
[CAS 111-65-9] Octane, all isomers ≥5% - <10%
Could this solvent be the reason I'm getting such low yields? If so, what should I use instead?

I've just tried STB from Cyb's salt tek and got the same results as with A/B. 1st pull 255mg and second pull 68mg (0.6% yield total)

Solvent seems to be OK. Are you using lab-grade chemicals?
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.

No, the only lab-grade chemical I'm using is distilled water. The rest (lye, vinegar, solvent) are store bought.
