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 […]

Continuous Flow Systems For Chemistry on the Cheap
Continuous Flow Systems run chemical reactions by continuously flowing reactants past each other. Pumps control fluid channels holding the reagents and chemical reactions occur at intersections of those pumps. It’s the chemistry version of the Lab On a Chip. Flow chemistry doesn’t have to be small-scale, it’s used in industrial manufacturing, but it can be […]
Pairing Plastic Printed Parts Professionally with 3DHubs
Last week we saw Holden Lab at Newcastle University start a discussion about using threaded fasteners to secure 3D printed parts. Dr. Robert LeSuer pointed out an extremely thorough discussion on the matter on 3DHubs.com . 3DHubs has an incredible wealth of information on DIY construction, including an amazing cost analysis of 3D printing vs […]
ElectroPen: An ultralow-cost piezoelectric electroporator
Electroporation is a powerful alternative to heat shock for delivering small molecules such as plasmids across cell membranes. By application of an electrical field netivetly charged DNA is forced into elector-competent cells by an electrohoresis-type effect. Electroporators can be expensive, generally over $2000, hence the popularity of more chemical solutions such as heat shock. Enter […]
A 3D-printed Droplet Generator
This week the Harris Lab at Brown put up a paper on the creation of a 3D-printed droplet generator. The system is based off a previously published design by David Harris which generates droplets on the scale of 1 mm. This new system now provides ample open-source instructions, and is fabricated with a 3D printer bringing the […]
