Impressive user interface and small footprint


Average Rating 5.0

Application Area:

Cell density measurement

We achieve quality results with the greatest accuracy between 0.1-0.3 range. As OD600 increases, there is more interference, and the output number becomes less linear. That being said this is not the most accurate device on the market, but for the value and user interface this is a phenomenal tool to take rapid measurements and results are easy to interpret. The footprint of this device is incredibly small making it transportable and able to use just about anywhere. I hope to see Byonoy software being available for more device interfacing, such as Apple products. The sales team has been attentive and very quick to respond to questions and troubleshooting. I feel this has been worth our dollar and look forward to continuing a relationship with Byonoy.

Durable, portable, good data. Can be picky about the ambient light.


Average Rating 4.7

Application Area:

Amino acid quantification, 280nm

I used this cuvette reader for amino acid quantification in the UV (280 nm), and it worked well and gave reliable, reproducible results. It is easy to use, although it can be a bit picky about the ambient light conditions - I found that I needed to turn certain lights in the room on or off, and I sometimes needed to exclude natural light to get successful readings. I think that these problems could be circumvented with the addition of a small cover, or it is certainly possible that the lighting in our field lab was odd. That said, even in our field lab in the tropics I was able to get consistent readings and nice data. The software is intuitive and works smoothly. Overall, I would absolutely recommend this spectrophotometer for field work and teaching labs. It is super portable and easy to set up. It is also durable - I accidentally knocked it off the table, put it back, and it kept on working. Perfect for field work, and really an impressive little machine.

Meet Absorbance One, the UV/VIS spectrophotometer, that's bespoke to your assay!

Into the Darkness: The discrete design of the Absorbance One places it among the premium cuvette spectrophotometers. Capable of reading up to 5 OD, the Absorbance One pushes the boundaries of dynamic range, while wavelengths from 340 to 1,000 nm allow for a wide variety of endpoint and kinetic assays. The Absorbance One is capable of reading multiple cuvette variants, allowing for standard, semi-micro, and microvolume measurements.

Almost Magical: Byonoy‘s ambient light cancelling technology results in an open design, allowing the user to place the cuvette directly into the reader. Loading initiates an automatic measurement in a fraction of a second and results are displayed instantly in the Absorbance One App.

Auto cuvette-detection, auto initialization, auto measurement: A single USB cable connects the device to a computer, tablet or smartphone and provides access to the Absorbance One App, where a clean and user-friendly interface allows measurement results to be easily recorded and exported in the desired digital format.
