ABS & ABS Plus

The SpectraMax ABS/ABS Plus Microplate Readers

provide fast absorbance detection without the use of filters with monochromator-based wavelength selection for visible and UV-visible absorbance.

Our absorbance plate readers feature our PathCheck Sensor technology and industry-leading SoftMax® Pro Data Acquisition and Analysis Software. They can be combined with our StakMax® Microplate Stacker and can be easily integrated with leading partner robotic systems.
