The DU Series 700 Spectrophotometer is a complete scanning UV/Visible spectrophotometer with a bandwidth of 3 nm and a wavelength range of 190 to 1100 nm. The instrument comes with a complete set of application programs and multi-language support.

The DU 730 contains the following modes: Fixed wavelength, time-based kinetic, wavelength scanning, single component analysis, protein assay analysis, nucleic acid analysis, % dye incorporation, and DNA/protein tools.

You can use the DU Series 700 for testing samples in the visible and ultraviolet wavelength spectrum. A halogen gas-filled tungsten lamp produces light in the visible spectrum (320 to 1100 nm), and a deuterium lamp produces light in the ultraviolet spectrum (190 to 360 nm).

The DU Series 700 Spectrophotometer provides digital readouts in Absorbance or % Transmittance as well as calculated units, depending on the mode. USB ports for a printer, keyboard, and memory devices are standard.

When you select a user-generated or programmed method, the on-screen menus and prompts direct you through the test. You can also use these menus to generate reports, run statistical evaluations of generated calibration curves, and report instrument diagnostic checks.

All of our equipment is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
