This article shows how the absorbance maxima of Ponceau-S is determined over a wavelength range of 220nm to 800nm using the Eppendorf BioSpectromenter ®. The methods of analysis using this ...

This guide on troubleshooting will enable users to get reliable results when quantifying nucleic acids through various devices available in the Eppendorf photometer series (Figure 1). Therefore, the ...

Colorimetry is the field of determining the concentration of a coloured compound in a solution. A colorimeter, also known as a filter photometer, is an analytical machine that acts as the tool ...

New Tools Bridge Gap between Single and Multiple Sample Absorbance Instruments For generations after Gustav Kirchhoff and Robert Bunsen deduced that almost all molecules in nature absorb and emit ...

Proteins containing the appropriate amino acids are absorbent to light on the UV-spectrum, specifically light that has peak wavelengths of 260 – 280 nanometers (nm). This makes it simple to analyze ...
