I agree - interesting replies! Good to learn something new.
I had no idea there were instruments used for hydrocarbon service that incorporate wood. Never seen one, not in 28 years, not in the oilpatch, refinery, bulk station, railyard, or retail - with the exception of some wooden tank dippers a long time ago on farms (thanks for the reminder!). Everything I've used was either Nalgene or other inert polymer, metal, or glass. And the occasional natural cork for a thief sample.
Maybe my experience is too modern - or maybe the regs are different in different places.
