SpectraMax M5 / M5e is a dual-monochromator, multi-detection microplate reader with a
triple-mode cuvette port and 6-384
microplate reading capability. Detection modalities include absorbance (UV-Vis), fluorescence intensity (FI),
fluorescence polarization (FP), time-resolved fluorescence (TRF) and luminescence (Lum). The optical performance is
comparable to a top-of-the-line dedicated spectrophotometer or spectrofluorometer with no trade-off between instrument
performance and the number of read modes.
The M5e offers the additional benefit of being certified for the Cisbio HTRF assay.
Endpoint, kinetic, spectrum and area-well scanning read types and Molecular Devices' PathCheck® Sensor allow
homogeneous and heterogeneous biochemical- or cell-based microplate assays to be performed in one flexible system.
The SpectraMax M5 / M5e allows easy conversion and optimization of very-low-throughput
to medium-high-throughput assays,
faster, more precise results and reagent savings. In addition, assays requiring a read in two or more modes can be
combined and run by issuing a single command.
Dual Monochromators
With the SpectraMax M5 / M5e, there is no need for expensive filters. The system uses two scanning monochromators to
determine optimal excitation and emission settings. Changing methods or fluorophores requires only a few mouse
clicks to optimize the system.
Patented PathCheck Sensor
PathCheck is the only patented technology available that measures the depth (optical pathlength) of
samples in a microplate. With SoftMax® Pro software, it can automatically normalize the well absorbance to a
cuvette equivalent pathlength of 1 cm—similar to using 96 or 384 cuvettes simultaneously. PathCheck allows you
to eliminate standard curves and, for compounds with a known absorptivity, concentration can be calculated directly
from absorbance.
Superior Optics
The optics in SpectraMax M5 / M5e are designed to give you optimal assay performance.
The reference diodes enable elimination
of measurement noise due to slight fluctuations in excitation light intensity. The angled emission beam improves
signal-to-noise, especially in narrow Stokes shift fluorophores, by reducing stray light. Elliptical mirrors are used
instead of lenses for maximum transmission with minimal wavelength distortion. Top-quality UV-grade fibers give the
highest light transmission down to even the lowest wavelengths.

Early ADME Compound Profiling Assays
SpectraMax microplate readers are ideal for increased throughput of early ADME compound profiling assays
such as the Transil® Membrane Affinity assay and
Transil® Human Serum Albumin Binding assay. The
Membrane Affinity assay provides high-throughput lipophilicity data equivalent to liposome-based methods
without the need for ultracentrifugation. The Human Serum Albumin Binding assay provides high-throughput
blood protein binding data by measuring the fraction bound to Human Serum Albumin.
Comprehensive Data Analysis
SoftMax Pro software provides data acquisition, analysis and
management capabilities, allowing cross-plate analysis and custom calculations. There is no need to
export data to a spreadsheet program.
Instrument & Software Validation
The SpectraTest® ABS1 absorbance and FL1 fluorescence validation
packages allow validation of optical characteristics. The
SoftMax Pro Software Validation Package and IQ/OQ/PQ validation
protocols provide tools for FDA 21 CFR Part 11 compliance.
robotics compatibility
SpectraMax microplate readers are the number one choice in microplate readers by our
robotic partners. The plate carriage design has no springs or clamps, and its
robotic communication interface makes integrating custom applications on the SpectraMax M5 / M5e straightforward.
The SynchroMax™ ET plate handler from Molecular Devices can be added to
increase the capacity to 320 microplates.
