FastSpec 528 Interface

Price: $ PACKAGE ONLY - not sold separately

The FS-528 is a spectrophotometer that operates in the range of 360-880nm. It simultaneous measures Fluorescense/ Absorbance / Scatter / Transmission for color comparisons, water quality tests, and timed kinetics activities at 16 wave lengths. Turbidity & nephelometry data is collected at 880 nm, the international standard wavelength.

Our newest interface, the microLAB FS-528 has added functionality and lower cost than the previous models.  By integrating the circuit boards for the FastSpec and Electrochemistry Module into the Interface circuit board, microLAB was able to dramatically reduce manufacturing costs and pass the savings on to you!

Technical Description

The name microLAB takes on a new meaning with out 5th generation FS-528 Laboratory Data System.  The FS-528 is a true stand alone "Micro-Laboratory".  It provides a wide variety of measurement, analysis, and sample management tools and does so with near research grade precision.  The FS-528 includes five new functions beyond the previous models: software controlled rotating magnetic stirring, adjustable sample illumination, a Constant Temperature Heater, a regulated power supply, and a tactile control for interactive "real-time control" of experimental conditions.  All of this has been added on to the existing platform capable of measuring temperature, pH, redox potential, pressure, conductance, voltage, dissolved oxygen, time, and FASTspecTM technology for fluorescence, absorbance, transmittance, scatter and turbidity measurements.
