Barnstead DIamond RO Water Filtration System w/ Filters

Current Stock:

Product Description

Manufacturer: Barnstead

Model: D12671

Condition: Used. Comes in non-original packaging. This system is in Fair overall cosmetic condition with minor scuffs/stains from prior use. The internal filters are all used, but there is a set of filters that are sealed in bag and look unused, with expiration dates in early 2021. The quick-release fitting on the feedwater inlet does not seal when no hose is attached, so we installed a hose barb with a pinched bit of hose to keep it all sealed for now (you can reuse the barb to build your hose when you get the system). The photos show the exact item(s) the buyer will receive.

Notes: This system was working in service when we removed it from a decommissioned lab setup.  The lights come on as shown when it is powered on with nothing connected. No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
