Regular calibration and proper cleaning of the optical surface are essential to maintain consistent and reliable performance. Its primary role is in nucleic acid quantification for downstream applications like PCR, cloning, sequencing, and microarray analysis, where precise input is essential.
Nanodrop Spectrophotometer Comparison: Key Differences and Choosing the Right One
The instrument assumes that all absorbance at 260nm is due to nucleic acids, meaning that contaminants like carbohydrates or phenol can artificially inflate concentration readings. The Core Principle: Spectrophotometry Made Simple At its heart, a Nanodrop operates on the fundamental principle of UV-Vis spectrophotometry.
It provides a rapid checkpoint for verifying that raw materials, such as plasmids or oligos, meet specified concentrations before they are used in manufacturing. The resulting A260/A280 and A260/A320 ratios are then compared against established purity ranges to give an immediate quality assessment.
