Hach DR/4000 U, UV-Vis Spectrophotometer, 1-inch-4 Position Carousel Adapter, Cuvette, Operations Manual and Power Cord
The DR/4000 Spectrophotometer is a powerful scanning spectrophotometer that gives you advanced capabilities and performance. It has ultraviolet and visible spectrum analysis capabilities with a range of 190 to 1100 nm, customer calibration, kinetics, time course and multi wavelength readings capabilities.
The DR/4000’s optical system consists of a Seya-Namioka split-beam diffraction grating monochromator, a light source and silicon photodiode detectors.Innovative reference beam technology ensures stable, accurate readings. A halogen gas-filled tungsten lamp the light source for visible spectrum analysis, while a deuterium lamp provides the light source for UV analysis. When you power up the DR/4000, a self-test procedure checks offset correction, wavelength calibration, lamp alignment, memory system and voltages.
Hach DR 4000 UV-Vis Spectrophotometer is accurate, easy to use, and affordable! By design, the Hach DR/4000 is ideally suited for both routine testing and demanding analysis in water treatment, industrial processes, surface finishing, food and beverage processing, pharmaceutical production, and chemical synthesis.
The DR/4000’s innovative sample modules slide in and to accommodate manual testing modules, multi-position carousels, pour-thru cells, a sipper system module, and a temperature control module. Plus, more than 130 preprogrammed use PA accepted Hach methods are permanently stored in instrument memory, and you may add up to 100 calibrations of your own.
Sophisticated Software
Using the DR/4000's sophisticated software and advanced interactive user interface, you can call up programs and wavelengths with just a few keystrokes. You get fast, accurate and convenient testing results when you use the DR/4000 with Hach simplified methods and prepared reagents.
Stable Analysis
The DR/4000 Spectrophotometer's optical design allows for an exceptionally stable analysis system to be compacted into a small, efficient package. A large graphical display with adjustable LCD shows graphical representations of wavelength scans, and peaks and valleys are available in tabular form.
Flexible software means you can choose readout values in concentration, ABS or %T, scan any wavelength range, perform time-course operations, or use the innovative standard addition function to check for accuracy.
