Eppendorf Biophotometer Spectrophotometer Visible/Absorbance Reader
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.

- 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
- Storage of the last 100 results and all corresponding data
- Storage of all calibrations
- Sample data and calibration data can be called up after being stored
