DNA Quantification with the UV Open Colorimeter
In this post we share some information on using the UV Open Colorimeter with a 255nm UV LED board for nucleic acid measurements.
Protein Quantification with the UV Open Colorimeter
In this tutorial we are using the new UV Open Colorimeter for A280 protein quantification measurements using a UV sensor and 270-280 nm UV LED
Background
Protein concentration is an extremely useful and routine measurement in science with a wide variety of applications in biochemistry, molecular biology, environmental and biomedical
Measuring proteins with the Bradford assay
Methods for measuring protein concentration using the Open Colorimeter and 595nm LED.
Soil Active Carbon - POXC
This week we have a guest author post from Fabricio Cano, Pablo Cremades and Nano Castro. They are members of reGOSH in Argentina where they have been developing open hardware tools and methods for measuring soil active carbon.
Measuring beer color with a 430nm colorimeter
Revisiting and sharing some of our earlier work developing a beer color test for home brewers.
Measuring turbidity with a modified Open Colorimeter
In this post we describe a prototype right-angle (R/A) cuvette holder for turbidity measurements.
Ammonia, nitrate and nitrite Open Colorimeter assays for water quality testing
Testing three water quality tests for the Open Colorimeter. These assays are ammonia, nitrate and nitrite.
