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.
With more than 30+ years of plate reader expertise and life science research, we’ve amassed an extensive collection of application-focused content in our Resource Hub. Our featured absorbance application notes include:
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.
ELISA (enzyme-linked immunosorbent assay) is a method used to quantitatively detect an antigen within a sample. An antigen is a toxin or other foreign substance, for example a flu virus or environmental contaminant, that causes the vertebrate immune system to mount a defensive response.
Absorbance, also known as optical density, is the quantity of light absorbed by a solution. Microplate readers with absorbance read capability are widely used in biological and chemical research, drug discovery and quality control.
