Clean, functional and in excellent working condition. This spectrophotometer was very recently in service at a well maintained wine production lab before the facility closed its doors. Service contract maintenance and calibration were regularly conducted and the unit was well cared for by knowledgeable technicians. This unit was in use and functioning well at the time of the lab closure but the records don't seem to list its regular July 2021 maintanence. This unit has some light liquid staining on the exterior but is in otherwise excellent cosmetic condition.
This unit is currently fitted with the sipper assembly for automated, continuous sample reading. This system was a favorite with the lab technicians and was more frequently used that newer, more feature packed models due to its consistent, reliable results. A true staple of any lab setting, ready for long term productivity in your lab.
We have a full suite of manuals and software for the DU-800. Because of the fact that we have multiple DU-800's but, in the interest of space, only one copy of the manuals/software, we will be listing the suite separately for those that need it. If you don't have the software and would like a copy of the disc with your order, please let us know.
Hassle Free Warranty.
**We're on the fence about whether this unit should be shipped via standard carrier or freight. In appropiately protective packaging it is unwieldy and relatively heavy...the perfect target for box carrier abuse. This favors us to prefer freight shipping for the sake of the equpment. If you are willing to risk a box carrier, we are open to discuss it. Otherwise, contact us for a freight quote.**
