Would anyone be interested in purchasing a retired but functioning IV pump for their pressure filtration setup? The units are shelved after so many hours of use, they still work fine but they are considered expired units, wasteful as hell. I知 trying to gauge interest before I tell this person yes and end up with 20 pumps I have no use for. Just kind of seeing if people would be interested. I値l post details and pics of the pumps once he sends them to me.
