Measuring proteins with the Bradford assay Methods for measuring protein concentration using the Open Colorimeter and 595nm LED.
Measuring beer color with a 430nm colorimeter Revisiting and sharing some of our earlier work developing a beer color test for home brewers.
Open Colorimeter Plus: Implementing the dual light sensor design In this post we provide an update on the Open Colorimeter Plus design. Using different white light LED boards we measured baseline light intensity and the scattered light intensity from a single 100 NTU turbidity standard.
DNA Quantitation with the Open Colorimeter Plus In this post we describe how to perform DNA Quantitation with a commercial dsDNA fluorescence kit and our new Open Colorimeter Plus.
Update on developing a turbidity test with the Open Colorimeter This is a continuation of our documentation on developing a turbidity test for the Open Colorimeter. Check out part one below for more background on this project! Measuring turbidity with a modified Open ColorimeterIn this post we describe a prototype right-angle (R/A) cuvette holder for turbidity measurements.IO Rodeo
