SpectraMax Spectrophotometers for UV-Vis Absorbance Detection

The SpectraMax® absorbance spectrophotometers and plate readers provide the versatility and convenience for a wide range of assays such as ELISAs, nucleic acid and protein quantitation, and microbial growth.

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.

We also provide GxP compliance and validation tools for optimal GLP/GMP lab performance.

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.

What’s the difference between an absorbance spectrophotometer and a microplate reader?

A standard spectrophotometer measures the absorbance of one sample at a time. The sample is typically placed in a cuvette through which light is sent horizontally. An absorbance plate reader offers higher throughput and can measure the absorbance of samples in microplates (typically 96-well or even 384-well) by sending light through each well vertically.
