Beckman DU 730 UV/VIS Life Science Spectrophotometer
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.
Most 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.

Yes, all equipment from American Instrument Exchange comes with a warranty.
Used/reconditioned/refurbished equipment is tested to make sure it operates to the manufacturer’s specifications and comes with a 90-day warranty (unless otherwise noted). New equipment comes with a warranty from the manufacturer.
Testing requirements vary across all the equipment categories we sell. Temperature controlled units are tested with NIST traceable probes and data loggers. Gaskets, external housing, glass, handles, controls and control screens are all thoroughly inspected for integrity and functionality.
We test all equipment using the manufacturer's parameters and specifications to confirm that the unit operates properly. While we may not be able to test for specific analytical applications we do our best to simulate the conditions under which the equipment will be used in your lab. If you have particular testing requirements please let us know and we’ll work with you to make sure these are addressed during testing.
We can ship products both nationally and internationally using a well-established network of transporters. Smaller items will ship via UPS. Larger equipment will be palletized and shipped either LTL or air-ride, depending on the specific equipment and/or delivery requirements. In many cases we can offer inside delivery. Customers are also welcome to make pick-up arrangements using their own preferred carrier.
All shipments are FOB Haverhill, MA. American Instrument Exchange will take reasonable steps to protect the equipment during shipment and the equipment will be fully insured. The customer will be charged for all shipping and handling charges, and fees incurred in the process of delivering the order.
For local customers in and around New England we can offer shipping and delivery using a local moving company trained by our staff to handle and deliver lab equipment. Our local movers can provide either standard dock-to-dock delivery or bring the equipment into your lab and set it in place.
Prior to signing the POD (Proof of Delivery), you are responsible for inspecting the goods for any damage. You MUST note any damage on the POD prior to letting the driver leave. This is to protect you, the receiver of the goods in the unlikely event of any damage. Once you sign the POD free and clear from damage, the goods are then deemed delivered in good order and no further claims would be applicable. This is the standard for all transportation so we want to protect you, our valued client.
American Instrument Exchange will accept the return of any product that is not working as represented and could not be replaced or repaired to the customer’s satisfaction by American Instrument or a technician hired by/vetted by American Instrument Exchange’s during the warranty period. The customer will be responsible for proper packaging of the equipment and all included accessories.
Customers who cancel orders after refurbishing has begun or after delivery where there are no equipment performance issues will be subject to a cancellation and restocking fee of between 20% and 40% and responsible for the full total of the shipping & handling costs for both the delivery and the return of the equipment.
