An Open-Source Plate Reader

Plate readers are instruments which are used to detect properties of samples in microtiter plates, via absorbance, fluorescence, and luminescence. Karol Szymula, Michael Magaraci, Michael Patterson, Andrew Clark, Sevile Mannickarottu, and Brian Chow published a paper in September 2018 detailing the construction and performance of an open-source plate reader. The extensive supplementary materials provide everything you will need, from software to parts list to a […]

Open-Source Potentiostats for Electrochemical Detection

Potentiometry measures the potential difference between an indicator electrode in a solution and a reference electrode. This provides a quantitative non-destructive measurement of a liquid sample. A common electrode is the glass-membrane electrode used in a pH meter., but various indicator electrodes are designed for specifically for various solutions. The potentiostat is an unloved staple in most wet-labs […]
