[Soxhlet]

do you remember this gem?

Heat shrink instead of vacuum grease?

I have a food grade version i don’t advertise. We have a fresh batch in the way from Europe in a week. It was helium leak detected at 11 scale. This is fda certified grease and completely non toxic. It cost 125 a tube shipped. [IMG_2544]
