SpectraMax ABS, ABS Plus Absorbance ELISA Microplate Readers

The SpectraMax ABS and ABS Plus absorbance microplate readers provide the flexibility, sensitivity, and convenience for a wide range of assays such as ELISAs, microbial growth, and protein quantitation. Both readers feature an 8-channel read head for fast reads and a subset feature, the temperature independent PathCheck sensor that automatically normalizes and ensures accurate absorbance values by detecting pipetting errors. Combined with a wide application base, industry-leading SoftMax® Pro Software and validation tools, these readers fit in every lab and every budget.

Eliminate Filters
Eliminate the need for purchasing and changing out filters with monochromator-based wavelength selection for visible and UV-visible absorbance

Get consistent Results
Mix samples thoroughly in microplate wells with user-programmable Automix feature and monitor temperature-sensitive reactions with consistent temperature regulation from ambient to 45°C.

Integrate with ease

Measure micro-volumes: Compatible with the SpectraDrop™ Micro-Volume Microplate, enabling high-throughput measurement of low volumes (<5um) – ideal for DNA, RNA and protein quantification.





Pipetting errors eliminated
This reader utilizes Molecular Devices' temperature independent PathCheck Sensor technology to measure the depth (optical pathlength) of samples in a microplate. It also allows for the elimination of standard curves

Optimized optical path
The reader’s unique quartz fiber optic system minimizes stray light for precise readings across a microplate. The spectral resolution ensures accuracy of DNA absorbance measurements.

Read a variety of plate formats
SpectraMax® Absorbance Microplate Readers can run both cuvette-based and microplate reader applications on the same instrument. Read one sample or up to 384 in a single plate read using any standard cuvette, or 96- or 384-well microplate.

Validation made easy
Verify the accuracy of your absorbance measurements with the SpectraTest® ABS1 Absorbance Validation Plate, using NIST-traceable standards. Testing can be done in your own lab, on your own schedule.
