The Beckman Coutler DU 730 Uv/Vis Spectrophotometer gives you precise, repeatable results in a small package, well suited to life science applications. Using a focused beam design, the narrow bandwidth of this spectrophotometer allows you to scan small samples at a superior resolution. The narrow beam eliminates the need for masking, and by using the entirety of the energy, a wide dynamic range and linearity is achieved. The Beckman Coulter DU 730 UV/Vis Spectrophotometer is intuitive to navigate, using a touch based interface, and powerful but simple software servicing a wide array of applications. Applications including fixed wavelength, wavelength scan, kinetics over time, single component analysis, protein assay analysis, nucleic acid analysis, dye incorporation, and DNA/protein tools.  Up to 50 user protocols can be created and stored, quickly recalled and applied.

The Beckman Coulter DU 730 UV/Vis Spectrophotometer has a variety of beneficial features, you may choose from startup diagnostics and a range of system checks to ensure the instrument performs to specifications, whether either of the UV and Visible lamps are turned off conserving lamp life. This UV/Vis spectrophotometer has USB ports to allow for plug in and play printers and keyboards, and data may be exported either via USB memory stick or CSV format. The Beckman Coulter DU 730 can be protected by a password with individual access control. The cells of this uv/vis spectrophotometer are easy to clean, samples can be recovered easily, if they’re not diluted. The Beckman Coulter DU 730 comes with a single cell holder, with the transport mechanism for a 7 position carousel built in.
