Beckman Coulter DU640 Spectrophotometer 190-1100nm 110/120V 50/60Hz 200W - Parts

Current Stock:

Product Description

Manufacturer: Beckman Coulter

Model: DU640

Condition: For Parts or Not Working. This Spectrophotometer is in fair to poor cosmetic condition with scuff, scratches, and general wear from regular industrial use.  The enclosure is no longer firmly attached to the unit and wants to separate when pulled up.  There is no monitor or keyboard included.  The inside of the machine is visibly dirty with sample material from past use.  Comes in non-original packaging. The photos show the exact item(s) the buyer will receive.

Notes: We powered on this Spectrophotometer and found that some aspects are functional and some are not.  We were not able to test fully.  When we powered it on the computer passed the post and begins a self-test.  There were a number of failures including the Detector (which sounded bad), Visible Lamp, Light Path, and Filter.  All other details passed the self-test.  For these reasons we are selling AS/IS and FOR PARTS. No manuals, cords/cables, or additional items are included if not listed or shown.
