Absorbance readers Visible

Absorbance determines the optical density of your product, by measuring how much of the initial (100%) light is transmitted through the sample: the loss in amount of transmitted light is related to the concentration of the molecule of interest.

It is important to know the spectral range for your application as well as the type of optics needed. The choice is between a filter, monochromator or diode array based wavelength selector.

Filters and monochromators select the wavelength prior to the sample; the diode array splits the light after the sample and uses an array of detectors. For sensitive measurement it is advised to work with a system which selects the wavelength prior to the sample, for quick full spectrum measurement and flexibility, a diode array is preferred.

Beside the optics, the type of lamp in the Spectrophotometer is important; it is critical for the wavelength range which is available.

We offer a variety of dedicated Plate readers for measuring absorbance.
