Overview
The Modulus™ Microplate Multimode Reader is skillfully designed for
today’s life science laboratory. In addition to having performance on
par with single-mode instruments, the Modulus™ Microplate blends
user-friendly operation with easy data handling and flexible purchasing
options. The result of this design is an instrument with superior
performance that is easy to use, is affordable, and can be customized to
your laboratory’s needs.
Performance
The Modulus™ Microplate Multimode Reader combines the superior
performance expected from single-mode instruments with the functionality
of multiple modes. To achieve industry-leading performance, the Modulus™
Microplate is designed with optical channels dedicated to each
individual technology. Unlike other multimode systems, readings taken
with the Modulus™ Microplate are not degraded by indirect fiber-optic
transmission or crowded optical channels. Dedicated optical channeling
ensures that the Modulus™ Microplate provides sensitivity and dynamic
range on par with the highest performing single-mode instruments.
Ease of Use
The Modulus™ Microplate Multimode Reader is designed to be put into
use straight from the box, without the need to read a manual or obtain
special training. To achieve this plug-and-play usability, the Modulus™
Microplate combines a color LCD touch screen with a Windows-based
onboard computer. The built-in computer eliminates the connectivity
hassles, cost, and space requirements of running an external computer.
Assay set-up on the Modulus™ Microplate is effortless with several
flexible set-up options to choose from. Once an assay is run, data can
be transferred in Excel-compatible .csv format from the Modulus™
Microplate using the built-in USB drive and the USB stick that comes
with the instrument.
Affordable Modularity
The Modulus™ Microplate is a modular instrument that easily fits into
most budgets. Purchase the technology or modes that you need now and add
onto the system later as your needs expand. For example, the Modulus™
Microplate can be purchased as a luminometer, then fluorescence and/or
absorbance modules can be purchased and added later.
There is no need for a service call or downtime. Installations take less
than ten minutes and can be done right in your lab using just an Allen
wrench which is provided with the module. In addition, after installing
a new module, you will not need to download and install new software.
The Modulus™ Microplate instantly detects the newly installed module(s)
and will automatically adjust screens, protocols, and options.
Figure 1: The Luminescence Module light path is
isolated through a dual-masking system at both the detector and at the
well being read. The dual-masking system is designed to eliminate stray
light by creating a column through which the light from the sample
passes to the detector.
Figure 2: The Fluorescence Module uses an
epifluorescent design to ensure a consistent measurement position. This
approach reduces the impact of small sample volume fluctuations by
consistently measuring the sample at the same position from well to
well.
Figure 3: The Absorbance Module comes with four
factory-installed filters for measuring ELISA and protein quantitation
assays. In addition, custom filters can be easily added to the two
removable filter paddles for expanded assay options.

Luminescence Module(Factory Installed)
The Modulus™ Microplate Multimode Reader with the Luminescence Module
is designed to deliver performance equivalent to dedicated microplate
luminometers while also offering the flexibility of a multimode reader.
To achieve sensitivity on par with that of a dedicated luminometer,
the luminescence channel is separated from other measurement
technologies and positioned directly above the sample well. These
conditions maximize light capture for the best possible sensitivity. In
conjunction, a low-noise photomultiplier tube ensures that collected
light is not compromised in any way. This design makes the Modulus™
Microplate between 10 to 1000 times more sensitive than competing
multimode luminometers.
In addition to high sensitivity, the Modulus™ Microplate boasts
greater than 8 logs of dynamic range, eliminating the need to dilute
samples or manage detector-driven gain changes. To achieve this extra
large reading range, the Modulus™ Microplate is capable of
simultaneously measuring samples of varying brightness. The
photomultiplier tube automatically adjusts for the optimum reading of
bright or dim samples. This means that the Modulus™ Microplate is
capable of achieving a reading range of 2 – 3 logs more than competing
multimode luminometers.
For further functionality, a Modulus™ Microplate with the
Luminescence Module is designed to reduce crosstalk. The luminescent
light path is isolated through a dual-masking system at both the
detector and the well being read. Dual masking eliminates stray light by
creating a column in which the light from the sample passes directly to
the detector. When using 96-well white plates, this dual-masking system
effectively results in a crosstalk rejection of 5 x 10-5.

Fluorescence Module (User Installable)
A Modulus™ Microplate Multimode Reader with the Fluorescence Module
installed is designed to deliver both high performance and user
flexibility.
To achieve high performance, the Fluorescence Module utilizes
powerful light-emitting diodes (LEDs) as excitation sources. LEDs have
very specific light-output profiles which closely match the excitation
profiles of commonly used fluorescent molecules. LED usage increases
sensitivity by fully exciting the fluorophore and reducing non-specific
light leakage, a problem often found when using broad-spectrum light
sources. Additionally, the Modulus™ Microplate Fluorescence Module uses
an epifluorescent design to ensure a consistent measurement position.
This pinpointed approach reduces the impact of volume fluctuation within
small samples by reliably measuring at the same position from well to
well.
The Modulus™ Microplate Fluorescence Module accepts different
Fluorescence Optical Kits for measuring a variety of fluorophores. Four
standard optical kits are available to measure the most popular
fluorophores including Hoechst dye, fluorescein, rhodamine, Cy3, and
Cy5. In addition, custom optical kits can be readily made for
non-standard applications. Optical kits can be easily exchanged in
seconds and built-in software ensures that the installed optical kit
matches the selected application protocol. Protocols for nucleic acids
and proteins such as PicoGreen®, RiboGreen®, and Quant-iT™ assays are
preprogrammed into the Modulus™ Microplate for your convenience.
The Modulus™ Microplate Fluorescence Module is designed as a
user-installable module. This means that you can either buy the
Fluorescence Module now or add it to your system later when your lab is
ready to run fluorescence experiments. The ability to add modules as you
need them gives you great purchasing flexibility. Installation is easy
and takes less than ten minutes with the provided tool. There is no
downtime or need for a service call.

Absorbance Module (400 - 800 nm) (User Installable)
By purchasing the Modulus™ Microplate Multimode Reader with the
Absorbance Module installed, the instrument stands alone as a
high-performance photometer. As an alternative, purchase the Absorbance
Module later and install it yourself. Installation is easy and takes
less than ten minutes with the provided tool. There is no downtime or
need for a service call.
The Modulus™ Microplate Multimode Reader with Absorbance Module
provides measurements that are highly sensitive and cover a wide dynamic
range. The absorbance channel has a reading range of 0 - 5.0 Optical
Density (OD) with an accuracy that deviates less than 2%. The channel
consists of a white LED with a spectral range of 400 to 800 nm
positioned at the bottom of the instrument. As it shines through the
bottom of the plate, your sample absorbs the light in a wavelength range
that is dictated by your individual application. The final stage for
measuring absorbance involves the light passing into a large-area
photodiode where it is measured and processed.
The Absorbance Module comes with two open filter slots and four
factory-installed filters. The preinstalled filters are for 450, 560,
600, and 750 nm as these cover the most common ELISA and protein assays.
With two open filter slots, you can also customize the absorbance module
by adding the filter paddle of your choice. In addition, it is easy to
run ratiometric absorbance-based assays to adjust for optical
imperfections. Simply use the color touch screen to select the two
desired wavelengths. OD values for each wavelength or a ratio of the two
wavelengths will appear on the easy-to-read display screen.
Intuitive User Interface
The Windows-based computer built into the Modulus™ Microplate Reader
offers dynamic user-interface capabilities. Simply choose from three
options on the instrument touch screen to start setting up a run.
Injectors
Both single and dual injectors are available for the
Modulus™ Microplate Luminometer. Each injector has a volume range of 25
– 200 l in 5-l increments. Installed injector systems are automatically
recognized by the instrument and controlled using the touch screen and
fluidics wizard. Prime and Flush commands provide easy maintenance and a
Reverse Purge command saves valuable reagents. Injectors are recommended
for labs running experiments with flash-based luminescence applications
or dual-reporter assays.
Luminescence Light Plate
The optional Luminescence Light Plate provides an external control to
confirm that the luminometer functions properly. Some labs require this
additional verification procedure. Reading the light plate before taking
measurements is a quick and easy way to ensure quality control over
linearity and consistency of readings.
Microplate Format
The Modulus™ Microplate Multimode Reader accepts 96-well plates
conforming to the SBS plate standard.
Data Analysis
