The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: SLM Aminco - Model: JD-490 - Condition: Used and in Excellent Condition - Price: $550.00 USD - Availability: In stock, 1 available - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 5 lb, estimated - Shipping dimensions: 14X14X6 in, estimated ## Categories - Lab & Analytical > Analytical Instruments (primary) ## Details ### Includes - (2) Anode BNC Cables, Approximate Length: 10 ft. - (2) HV Cables, Approximate Length: 10 ft. ## Function Spectrofluorometric system with photon-counting detection for quantitative fluorescence measurement across excitation and emission wavelengths. Delivers high-sensitivity, low-background photon-counting data via a PMT-based detector with spectral scanning, variable integration time, and wide dynamic range. Supports steady-state and time-resolved fluorescence measurements, with excitation-emission monochromator pair enabling precise wavelength selection and spectral resolution suitable for trace-level fluorophores. Includes external cabling for high-voltage supply and signal transmission. ## Images - - - - -
