Electrophoresis power supply - LCD display

Electrophoresis power supply - LCD display

We have recently updated the electrophoresis power supply [https://iorodeo.com/products/electrophoresis-power-supply] to include an LCD display as shown in the images below. The price of the power supply kits remains the same ($65 for a kit). We also have a fully assembled and ready-to-use

Making a custom electrochemical cell

Making a custom electrochemical cell

In this blog post we describe making a simple custom electrode mount that we used in cyclic voltammetry experiments with the Rodeostat potentiostat. The electrodes we used were purchased from CH Instruments but the custom mount could be easily modified for use with other electrodes.

Chronoamperometry with glucose test strips

Chronoamperometry with glucose test strips

In this electrochemistry experiment we used the Rodeostat potentiostat to measure glucose in liquids using commonly available glucose test strips. Glucose test strips are a type of biosensor - they convert biochemical reactions to an electrochemical signal. Each glucose test strip contains the enzyme glucose oxidase (GOx) and an electron transfer

Reversible Cyclic Voltammetry

Reversible Cyclic Voltammetry

In this blog post we carried out a cyclic voltammetry experiment with ruthenium hexamine Ru(NH3)6 a reversible redox couple.

Open source potentiostat features

Open source potentiostat features

In this blog post we give a quick overview of some of the main differences between two open source potentiostats: Rodeostat and Cheapstat.

Testing a lead colorimetric assay

Testing a lead colorimetric assay

In this blog post we describe our initial testing of a colorimetric kit for measuring lead in drinking water. In 2015, a Virginia Tech research team [http://flintwaterstudy.org/about-page/about-us/] found that over 40% of the homes in Flint, MI had elevated lead water levels with 25%

Measuring emission spectra for the blue LED transilluminator

Measuring emission spectra for the blue LED transilluminator

Our blue LED transilluminators [https://iorodeo.com/collections/gel-imaging] use a 470 nm LED array in combination with blue and amber acrylic filters for viewing DNA bands in agarose gels stained with DNA dyes. Images of gels stained with Greenview, GelGreen and others can be seen in previous posts
