The 225ATS is Buck's educational model, which comes with two powered lamp brackets on the back of the instrument, and one internal bracket. Their simple optical design gives this system superior energy, and better results than double beam AA systems. Our unique design also allows our instruments to have a smaller footprint and a lower cost.
The Buck Scientific line of Atomic Absorption Spectrophotometers were designed to utilize the maximum energy of the single beam optical system. This allowed them to build a smaller, less expensive and more sensitive instrument. Background correction was achieved by inserting the deuterium lamp directly after the hollow cathode lamp.
A general rule of thumb for optical engineers is every time a mirror is introduced into a lightpath it deducts 10% of the energy. So in this case, less really is more!
With a 10" touchscreen computer on-board guiding you through your analysis, using an AA Spectrophotometer has never been easier! The All new Graphical User Interface utilizes five tabbed screens for; Analysis, controls, library, calibration, and samples. The 4 front facing USB ports make connecting a mouse and extracting data onto usb flash discs easy! Our Hideaway keyboard makes naming your samples easy and conveniently tucks in when not in use.
