Eppendorf Biophotometer Spectrophotometer Visible/Absorbance Reader

Cambridge Scientific ID #: 22076


State-of-the-art technology with an easy-to-use format in a compact footprint: that is the Eppendorf BioPhotometer! It's large key pads, pre-programmed methods, and pre-set wavelengths and conversion factors greatly simplify the sample quantification. The large LCD screen displays the sample concentrations, absorption values, OD260/OD230 and OD260/OD230 and sample dilutions at a glance.



  • Compact design, easy to transport
  • Robust housing, splash- and water-resistant
  • High-value components guarantee high operating safety
  • Metal housing ensures high stability
  • Xenon flash lamp source with extremely long service life
  • Ready to measure immediately (no warmup time)
  • Self-explanatory, extremely simple operation
  • Measurement only takes approx 2 seconds
  • Programmed methods: ssDNA, dsDNA, RNA, Oligo, Protein, Lowry/Lowry micro, Bradford/Bradford micro, BCA/BCA micro, and OD 600
  • Optional background correction at 320 nm for UV methods
  • Automatic calculation of sample dilution
  • Simple conversion using the "Conversion" key
  • Up to 10 standards for colorimetric analyses
