Thermo scientific genesys 20 spectrophotometer,4001-000
This listing is for a Genesys 20 spectrophotometer by Thermo Scientific. Catalog number 4001-000. Perfect cosemtic condition. Appears to be unused since the lamp hours are at 0. Holds cuvettes with 1 cm path length. Manual is NOT included. Pictures show it blanks properly and addition of dilute fluorescein caused the predictable abosrobance at 495 nm. Also, I measured fluorescein solutions at different dilutions and saw the expected linear absorbance response. New from Fisher Scientific, this item sells for $1874.60 (cat# 14-385-445). If not satisfied with your purchase for ANY reason, send it back within 60 days for a refund. Thank you for your interest.
