My lab has a VG Instruments Prism II SIRMS (vintage 1990) with a carbonate (common acid) system and multiport manifold that is available, either as an entire unit or for parts. If you or someone you know would have interest in this, please have them contact me ([log in to unmask]).
The system saw some water damage when the overhead plumbing leaked. I cannot vouch for the condition of the electronics but all of the mechanical systems should be fine.
There is some urgency in getting the system removed due to renovations taking place in the lab.
