Analytik Jena has announced the Bio version of the Specord 250 double-beam UV/Visible spectrophotometer.
The dynamic range of the instrument removes the need for samples to be diluted, while samples such as proteins can be analysed without the need for a head-on detector.
The device provides fast measurement of optical density/absorbance, enzymatic analyses of DNA or proteins and much more.
The high dynamic range provides truly linear absorbance to more than +/-4A with the Peltier-Cooled double-detection system.
A special cell position is available for measuring turbid and highly scattering samples such as proteins, which keeps energy losses at a minimum.
The high-performance optical system brings optimal signal to noise, fast analysis times, low detection limits, plus short- and long-term photometric stability.
With a double monochromator for reduced stray light contributions and variable bandpass, the instrument readily conforms to the standards of pharmacopoeias such as Ph Eur, BP, USP, DAB or JPXIII.
The Specord 250 Bio provides a variety of pre-programmed measuring methods for DNA and protein analysis, as well as the flexibility to quickly construct and store user-defined analytical methods for future use.
Quantitative analyses of protein concentrations for methods such as the Lowry protein method, Bradford assay, Biuret method and BCA assay can be made by creating and storing calibrations from measurements of standards.
