The ILab Aries is a new member of the Instrumentation Laboratory (IL) family of bench top analyzers. Able to perform photometry, turbidimitry, and potentiometry tests, the ILab Aries is the most productive analyzer in its class. Samples to be measured are easily accessible and can be continuously loaded, thereby avoiding any interruption of work in progress. The Aries can perform up to 220 tests per hour, with the number increasing to 440 tests per hour when using the ISE module. The Aries runs on Windows XP, and its user friendly interface requires only a single menu for all operations. The unit has 66 sample positions and has an integrated bar code reader used to track the samples. Reagent bottles are also bar coded. Sample analysis results are normally provided within a three to four minute time frame.
