SpectraMax ABS and ABS Plus Absorbance ELISA Microplate Readers
Filterless readers provide consistent results with steady temperature regulation
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 our patented PathCheck™ Sensor. The temperature independent PathCheck sensor 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.

SpectraMax ABS Plus Feature Demonstration
Features
-
Pipetting errors eliminated
This reader utilizes Molecular Devices' patented PathCheck® Sensor 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 mimics a dual-beam spectrophotometer. Each well has its own sample beam and reference detector. 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.

Applications of SpectraMax ABS and ABS Plus Absorbance ELISA Microplate Readers
-
ELISA
Enzyme-linked immunosorbent assays (ELISAs) are used to measure the amount of a specific protein, typically in a microplate format, and results are most often detected via absorbance in the visible wavelength range. Chemiluminescent and fluorescent ELISA formats offer enhanced sensitivity for accurate quantitation of less abundant analytes.

Chemiluminescent and fluorescent ELISA formats offer enhanced sensitivity for accurate quantitation of less abundant analytes.
Cell Viability
Cell viability can be assessed by examining parameters such as cell membrane integrity or the activity of cellular enzymes. On a microplate readers, these parameters can be detected using fluorescent reagents. For example, a red cell-impermeant, DNA-binding dye only stains dead or dying cells whose membranes are compromised, while a green live-cell dye only fluoresces when metabolic enzymes are active.
