This listing is for a Great Operational Condition SHIMADZU DOUBLE BEAM AA-6200 ATOMIC ABSORPTION SPECTROPHOTOMETER as can be seen in the pictures.
IMPORTANT: SOFTWARE IS NOT INCLUDED WITH THIS EBAY SALE SINCE THIS EBAY SALE DOES NOT INCLUDE THE COMPUTER NEEDED TO RUN THIS UNIT!!!
Picture is of the actual item buyer will receive, we took pictures in two different locations that's why some pictures have different light contrast from one another but the unit is exactly the same.

This unit was recently removed from service from a Federal University which took excellent care of it and that is why it is in such great condition.
Technical Information in Italics Blue below was taken from Manufacturer's website:
Equipment Description - Purpose of Use for Shimadzu AA-6200 Atomic Absorption Spectrophotometer.
Atomic absorption spectroscopy is used to detect trace amounts of specific elements in solution to a high degree of precision. The sample passes through an acetylene-air flame, upon which it is atomized. This collection of atoms contains mostly atoms in the ground state and very few that have been excited to a higher energy state by the flame. An element-specific lamp that produces light at an extremely narrow wavelength shines upon the collection of atoms in the ground state and the absorbance is measured. The concentration of the sample is then calculated using Beer's law from a calibration curve of standard solutions of known concentration.
Shimadzu's double beam AA-6200 atomic absorption spectrophotometer combines high performance with affordability. The double beam system provides the superior baseline stability expected from high-performance optical systems at an affordable price. A compact system, the AA-6200 uses some of the smallest bench space of an atomic absorption spectrophotometer in the world. In spite of its compactness, the performance and capability are superior.
Analysis of samples is relatively fast, compared to UV-vis spectroscopy. The path length in an AAS is also comparatively long (between 10 and 15 cm), which maximizes the accuracy of detection of trace amounts of analyte.
Relatively large sample amounts (around 1 to 2 mL) are required for analysis.
