The A3 Atomic Absorption Spectrometer is a high performance automated instrument designed to meet the requirements of the modern laboratory. Due to its versatility and performance it can be used for a wide range of applications.
Three flame options are available to the user with the Air/Acetylene being the standard configuration. This flame can be used for nearly all standard elements while the N2O/Acetylene and the Air/LPG (natural gas) are available as an option for the more demanding of elements. All three flame configurations offer coded burner for full safety protection.
The graphite head is fixed into the optical path to maximize performance and eliminate drift. The temperature of the transversely heated graphite tube is accurately controlled by means of a precision feedback system. Pyrolytically coated platform tubes are supplied as standard to improve the performance and eliminate many analytical problems associated with this technique.
The flame and graphite furnace can be changed over by a simple selection in versatile AA Win Pro software.
â—† Easy to use, complete software control
â—† Integrated safety precautions for user protection
â—† Flexible configuration for a wide array of industrial apps
â—† Time-saving high speed analysis

The SmartReader 96 comes complete with 4 popular filters: 405,450,492,630nm and twenty six additional filters are available separately to cover a full range from 340 to 750nm. The integrated filter wheel allows up to 8 filters to be loaded at once, and filters can be selected during programming. Up to two filters can be used for 2 measurements of the sample plate, for calculated comparisons. Kinetic calculations can be performed by setting multiple readings. The SmartReader 96 is a convenient stand alone reader, all software and the programing system is incorporated into the electronics. However, a convenient USB port on the side allows quick and easy saving of data files to a USB drive, and the universal .csv files can then be shared or transferred to a computer for storage or further processing. A data port can be used for connecting a computer or basic printer.

Accuris Analytical balances incorporate electromagnetic sensor technology and precision mechanical components to offer superior weight determinations to a fraction of a milligram. Two capacity ranges are available in the Analytical Balance line to weigh samples up to 120g or 210g. Readability for both ranges is 0.0001g (0.1mg), with accuracy and linearity specifications that match up with the top brands in the industry. The W3100 balances tare and stabilize quickly to provide immediate results. Both ranges offer an optional “Quick-Cal™” internal calibration feature that allows quick and convenient calibration without the need for a calibration standard weight. The glass draft shield enclosing the weighing chamber has sliding doors on the sides and top for easy access to the weigh pan. Leveling feet on the rear of the balance extend laterally to provide stability, and a sensitive leveling bubble aids in the leveling process.
The Accuris analytical balances have feature-rich software with different modes available for basic weighing in grams, ounces or carats, piece count weighing, determining percent deviation, and also check weighing for component inspection.
