It does this by detecting the intensity of light that passes through the clear reference pedestal when no sample is present, effectively calculating the exact distance the light travels through the liquid layer. Ensuring Accuracy and Maintenance The primary advantage of this technology lies in its simplicity and speed.

Furthermore, the ability to measure samples directly in their native state—without dilution in buffers—minimizes handling errors and preserves sample integrity for downstream applications. Eliminating the need for disposable cuvettes and extensive sample preparation reduces waste and saves valuable time in the laboratory.
The small sample volume requirement is particularly beneficial when working with precious or limited quantities of DNA, RNA, or protein. Because the sample is held as a droplet between two optical surfaces, the physical height of the liquid column can vary.

Regular calibration using certified standards verifies the accuracy of the absorbance readings. This ratio of intensities is the transmittance, which the software converts into absorbance units.
