This Pharmacia Biotech SMART HPLC USeperation UPeak Monitor UPrecision Pump 18180500 is in used condition and was removed from a working environment. This unit came from a local lab that had surplus inventory after upgrading equipment. Unit shows some aesthetic signs of normal use. We urge customers to view all photos as they show overall condition, included accessories and useful information. Please Note: As seen in photos the fraction collector door is missing. This does not affect functionality but the issue has been reflected in list price. At time of listing we do not have the means for full testing. We are however offering a 30 day full money back guarantee return policy on this system (buyer handling return shipping). We will be happy to answer any questions as well as provide additional photos so please feel free to contact us.
