The Eppendorf BioPhotometer Model #6131 is a versatile, single-beam photometer designed for rapid, simple, and convenient measurement of nucleic acids, proteins, and bacterial densities using photometric principles. Equipped with a xenon flash lamp, it offers fixed wavelengths at 230, 260, 280, 320, 562, and 595 nm and features a holographic concave grating for precise spectral dispersion. Its program-controlled wavelength selection and low spectral bandwidth—5 nm for lower wavelengths and 7 nm for higher wavelengths—combine with minimal systematic and random errors to deliver exceptional measurement accuracy, with a reading precision of 0.001 A and stray-light levels below 0.05%. Enhanced by 12 preprogrammed, modifiable method programs and high-quality silicium photodiodes for sensitive detection, this bio-photometer provides outstanding reliability and repeatability. All of these features are housed in a robust metal casing that ensures long-term operating stability, making it an indispensable tool for any laboratory.
The Eppendorf BioPhotometer Model #6131 is fully tested to perform at factory specifications before being shipped.
The Eppendorf BioPhotometer Model #6131 includes:
- > Calibration Certificate
- > Power Cord
- > Operator's Manual
- > Full 180 Day Parts and Labor Warranty
