This Amicon Moduline G90X500 Cast Acrylic Chromatography Column is in used condition and is guaranteed to be  functional. This column came from a local lab that had surplus equipment and 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: It is unclear if the model stamp indicates G90X5000 or the last zero was unintended. Please reference photos for column size. We will be happy to provide additional information as well as photos so please feel free to contact us with any questions.
