The Eppendorf BioPhotometer D30 is the third generation of Eppendorf BioPhotometers, which have become an established standard in the field of life sciences. It utilizes fixed wavelengths, making the Eppendorf BioPhotometer D30 the ideal device for quick and precise routine applications.

• Absorption measurements for one or more fixed wavelengths
• Integrated application and results memory
• Xenon flash lamp
• Compatible with microvolume measuring cells and standard cuvettes
• Integrated self-test and calibration history

The ultra-stable Xenon light source of the D30 quickly lights up for immediate instrument use

The D30 allows user to scan for specific UV applications with automatically determined purity ratios. Includes preprogrammed applications for quick start and applications with evaluation via factor, standard or standard series. Data transfer is made via USB interface, Ethernet or via e-mail and direct printout of results. Software process is guided to minimize errors. A Help box has explanation of each individual step in five languages.

Applications of the D30 include nucleic acid quantification, direct protein quantification (UV 280® nm), microvolume measurement via µCuvette G1.0 for highly concentrated samples, bacteria growth measurement (OD 600), and colorimetric assays for protein quantification, e.g., BCA, Bradford, Lowry. Also useful for 340 nm: assays using NADPH or NAPH, 405 nm: assays using para-nitrophenol, and 490 nm: cytotoxicity assays.

Data is clearly processed, making the evaluation of results fast and simple while minimizing mistakes. Additional help menus assist the user and offer an additional level of security. Relevant ratios are automatically determined for the corresponding applications. The Eppendorf BioPhotometer D30 offers the option of recording a scan for specific applications in the UV range. This allows a quick visual identification of contaminants in the sample.
