huh… 
glad to hear you’ve made progress.
however…
you have no way to actually know what you got without potency testing on your distillate.
basing production decisions on flawed or missing data isn’t a great strategy.
Consider acquiring In House analytics
if you don’t trust those that went before you, @zaxlol is correct, actually opening the wiper up to confirm the blades are still functional isn’t a bad move…the above were in a GLASS wiper (below were in a stainless one)
…presumably the operator could SEE the blades in the glass one…
extract?
or recover?
one implies COA on crude, the other on input biomass…
you only need potency, not a “full panel”.
