UV-vis is your standard?
The Eppendorf BioPhotometer D30 is the third generation of Eppendorf's well-established line of BioPhotometers. The compact instrument clearly processes data, records at fixed wavelengths and makes evaluating results fast and simple. For specific methods, additional measurements are recorded and displayed as a graph, making impurities easier and quicker to identify. More information

Product Information

The Eppendorf BioPhotometer D30 is the 3rd generation of Eppendorf spectrophotometers to become an established standard in the life sciences. Routine pre-defined wavelengths are easily selectable, allowing for quick and simple programming. Users are guided through every step of the assay with short, simple on-screen instructions. The ultra-stable Xenon flash lamp doesn't require any warm up time and a measurement typically takes 5 seconds. Raw and processed data are clearly presented on the large color screen and can be exported directly from the instrument in a variety of common formats. Eppendorf disposable UVette® cuvettes enable measurements with as little as 50 µL of sample and the Eppendorf µCuvette® G1.0 reduces this further to 1.5 µL of sample.

Nucleic acid purification is a major application in molecular laboratories. Purity and homogeneity of the sample are important considerations for subsequent applications. In practice, nucleic acids are purified with the help of commercially available kits which allow for the separation of most cellular components. However, the presence of proteins or other organic components in the eluate may not be entirely eliminated.
When purifying nucleic acid without a kit, additional contamination risks are posed by the chemicals used in the process, e.g. phenol or ethanol from a phenol/chloroform extraction. To ensure minimum contamination of the sample, it is essential to verify its purity by photometric measurements.
The ratios of the absorbance values at the wavelengths 230 nm, 260 nm and 280 nm (260 nm/230 nm and 260 nm/280 nm), provide a clear picture of the purity of a nucleic acid sample. The following values represent a pure DNA sample:
A260/A230 ≥ 2.0
A260/A280 = 1.8 – 2.0

Raw Data

In general, the purity of a DNA solution is easily defined using purity ratios. It is possible that reduced purity may be attributed to the fact that the sample is solubilized in water instead of in buffer. Since water and buffer have different properties, the absorbance of the sample being measured will be affected by this disparity.
For this reason, the BioPhotometer D30 is capable of recording a “Purity Scan” which displays the absorbance properties of a sample graphically, thus enabling fast and simple visual quality control.


In addition, all important raw data pertaining to the DNA sample are displayed in table format. The table optionally lists the purity ratios (A260/A230 and A260/A280), the absorbance values (raw data), as well as the background absorbance, e.g. at 320 nm.
Thus, the two display formats complement each other perfectly to allow for an evaluation of the quality of a DNA sample.
