The Absorbance 96 is a uniquely designed microplate reader for assays in 96-well format. By far the most compact reader on the market, the footprint of the reader is almost as small as the plate itself. Convinced by this entirely new design, the judges at the SLAS Conference 2019 recognized the innovativeness of the device and awarded the Absorbance 96 with the New Product Award. Despite its form, the Absorbance 96 delivers precise and accurate results at an affordable price. Together with the Byonoy proprietary software, the Absorbance 96 is ideal for a variety of applications, extending from ELISA to protein and cell-based assays. 


Main features and benefits of the Absorbance 96 Reader:

  • Space-saving design
  • Fast readout speed
  • Reliable measurement results  
  • Intuitive operation
  • Maintenance-free
  • Affordable price




Innovative Compactness

Our technological solution enables us to build the Absor-bance 96 in a unique compactness, with a footprint of about one microplate. Our vision was to develop a reader that meets the needs of the user and gives him the advantages of complete flexibility. The Absorbance 96 fits into any lab and saves valuable bench space. It can be easily transported within the laboratory and also between different laboratories. This makes it  the perfect analytic tool for those, who want to explore new possibilities.



Incomparable flexibility

Our goal was to develop a reader that would simplify the workflow in the laboratory. This philosophy of intuitive operation was translated into the Absorbance 96. The unique open design, in combination with the small size of the reader, leads to an entirely new user experience. A simple USB connection provides both the power supply and access to Byonoy’s user-control software, which itself functions via plug-and-play technology. Easily transported within – and between – different workspaces and laboratories, the Absorbance 96 fits into every lab, saving bench space and providing unprecedented flexibility.



Revolutionary Engineering

The Absorbance 96 is the first microplate reader on the market to contain 96 individual detection units. This means that all wells can be read simultaneously - in parallel - allowing for extremely fast photometric measurements. Without the need to scan across multiple wells, the Absorbance 96 has no moving parts. In combination with long-life LEDs, this solid-state design provides a maintenance-free user experience and ensures reliable, high quality results.




The Absorbance 96 allows to read out of wide range of applications. The following examples are some of the most important applications for the Absorbance 96:

  • Protein quantification assays
  • Cell-based assays, e.g. Cytotoxicity assays
  • Endpoint and kinetic assays




The Absorbance 96 is the first reader using a setup with 96 detection units. This innovative technological system operates without scanning mechanics and is free of maintenance requirements. Beyond that, the 96 detection units are utilized to measure in parallel to enable accurate and fast photometric measurements.



  • 96 detection units for fast reading
  • No scanning mechanics, no maintenance requirements
  • Four-channel LED-optics
  • No lamp changes needed due to long-life LEDs
  • Two year warranty

The four standard filters – 405, 450, 492, 620 nm – allow for a wide variety of ELISAs such as PNPP, ABTS, OPD and TMB. Other filter combinations for protein (Bradford or BCA), cell-based (MTT, XTT), or cell density assays can also be provided.
