Microplate Reader with PatchCheck®

The SpectraMax® 190 spectrophotometer is ideal for most life science applications, especially DNA analysis. For aqueous solutions, our patented* PathCheck® sensor technology senses the depth of the liquid in each microplate well, and normalizes the absorbance value to a 1-cm pathlength. The corrected absorbance is within 5% of the value obtained in a conventional spectrophotometer.  
Industry leading SoftMax® Pro microplate analysis software provides comprehensive instrument control and data reduction.
