there is a “waste” package adjustment excuse.
if you’re not using it, you’re probably not documenting your process appropriately.
I adjust every package for “waste: transfer losses from pyrex to jar. including tools”. occasionally shit goes sideways and there are greater losses. that gets a more detailed “excuse”.
We also document the weight of the biomass we chuck (waste: post-extraction biomass), then the solvent loss from leaving booth to leaving oven.
as MOISTURE: “solvent loss in oven” (yep that’s what they told us to do!). or “solvent/terpene loss during purge”.
biomass going into the machine gets a tag (new package).
extract going in to the oven is a “new package” (production batch; so we can “in house qc”), then it is “adjusted” as it moves along.
If we spin; that’s two new tags. if we combine batches (seldom don’t), that’s a new tag, and a new production batch, usually between oven and safe (more “samples”. got to get this shit dialed right? how?!?).
when spun, there are “waste” adjustments for “transfer loss ; pyrex, tools, basket” (THCA) and “transfer loss, pyrex, tools, centrifuge bottle”…and there was the occasional “shatter” which was documented either as “waste: broken jar, product contaminated with glass”, or repackaged with “contains GLASS” in product name (headed to distillate)…before “transfer loss, pyrex, tools, jar” became obsolete.
