Filter-based 96-well plate absorbance microplate reader for ELISA, Bradford, Lowry assays & more

Consistent Answers to a Rainbow
of Assays at Your Fingertips

The Ao Microplate Reader has a multitude of features to help you save time with arrays like ELISA, Bradford, and Lowry assays with wavelength ranging from 340-750nm. Each system comes with an 8 position filter wheel with 8 filters: 405, 450, 492, 595, and 630 standard, plus 3 from the filter catalogue, built-in shaker with speed selection, single and dual-read modes, and analysis software. The Ao Microplate Reader offers top-end performance and flexibility found in much more expensive models at an affordable price. 


Filters for Every Assay

5 Standard Filters: 405, 450, 492, 595, and 630 nm for most ELISA, Bradford, and Lowry assays

3 remaining filters are selected from our wide catalogue, ensuring you will have the filter solution for your assays

Key Features


Select from pre-set or custom protocols and analysis options.

The Ao Absorbance Microplate Reader makes measurement and analysis easy by creating a standard curve and performing sample calculations automatically.

Ao Plate Reader Software showing pre-programmed bradford protocol
Choosing and setting up an ELISA or Bradford protocol is easy on the Ao Absorbance Microplate Reader with easy-access pre-programmed protocols.


The 96-well format allows for the testing of multiple samples simultaneously while still allowing for a broad detection range.

Touch a sample type to select it, then touch the desired wells to assign that sample type to the plate layout.

Touching the standard and quality-control sample types brings out a submenu that allows you to select up to 12 different standards, and nine different controls.

View and analysis your raw data on a large, 7" touchscreen.

After reading the plate, the software opens a REPORT tab with raw data measurements. The standard curve can be viewed and printed by selecting CURVE in the REPORT tab.

The curve-fit and axes can be changed through the PROGRAM tab or the button beside the curve plot, even after a plate is read.

Ao Plate Reader Software ELISA
The absorbance values of standards plotted against a Histamine EIA Kit showing designated concentration values. Touch “CURVE” to view and print the standard curve generated from the absorption readings of the provided standards.


With options for fast or normal measurement speeds, you can have your data in as little as six seconds.

Print or export your results in either report form or as raw data. Data analysis is automatically performed by built-in software.

Your results are easily viewable and exportable using the large touch screen interface, minimizing the need for outside analysis or calculation software.
