BioPhotometer Plus UV/Vis Photometer from Eppendorf

With the BioPhotometer plus, Eppendorf offers a compact UV/Vis photometer for use in molecular biology, biochemistry and cell biology. The photometer provides instant, out-of-the-box access to 32 routine methods, of which 9 methods are freely programmable:

  • Measurement of DNA, RNA and protein concentration (UV and colorimetric)
  • Incorporation rate of fluorescent molecules (550 nm/650 nm), e. g., for microarray experiments
  • Enzymatic assays (e.g., peroxidase, alkaline phosphatase, β-galactosidase)
  • Optical density of cells (OD 600)

Both measurement and calculation of results are performed at the press of a button, and the results of the analysis, as well as all accompanying data, are available at a glance. This guarantees safe, error-free operation and reliable results.

In addition to its low weight, the photometer is small, yet extremely sturdy due to a robust metal housing, which allows for easy transport and cleaning.

The BioPhotometer plus is designed for use with cuvettes such as the Eppendorf UVette®, but is also optimized for measurement of small volumes through the use of microliter cells such as Hellma® TrayCell.
