The SpectraMax® ABS and ABS Plus Absorbance ELISA Microplate Readers bridges the gap between the affordability of filter-based readers and the flexibility of monochromator-based systems with PathCheck® Sensor—the only patented technology available that measures the depth (optical pathlength) of samples in a microplate. 

SpectraMax® ABS and ABS Plus absorbance microplate readers – A Filterless reader provide consistent results with steady temperature regulation 

The SpectraMax® ABS and ABS Plus absorbance microplate readers provide 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 a 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.

Key Features of SpectraMax® ABS and ABS Plus absorbance microplate readers 

  • 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.

  • Eight-channel optics

    The optical design of the reader enables simultaneous detection of 8 wells. The eight-channel system delivers both precision and speed across the microplate.

  • Dual wavelength reads

    The reader delivers high performance with round-bottom, flat-bottom or half-area well plates. Dual wavelength readings report the actual absorbance at each wavelength making data analysis convenient.

  • Flexibility to 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.
