A polarimeter is used to characterize a sample by measuring the rotation of polarized light when it interacts with the sample. They can cost upwards of ~$10,000, but a $350 DIY high-resolution polarimeter has recently been detailed in a paper by Andrew Harvie , Tom Phillips, and John deMello. The bill of materials for the […]

A DIY $125 liquid–liquid separator
Separating mixtures of immiscible liquids is a critical process in flow chemistry. Andrew Harvie, Jack Herrington, and John deMello have written a paper detailing how to make a useful piece of equipment to separate immiscible liquids for just $125. The project makes use of 3D Printing, a drilled out block of aluminum, a positional servo […]
MiCube: A modular fluorescence microscopy framework
miCube, not to be confused with µCube, is an a open and modular framework for the design and assembly of florescence microscopy optical devices, including devices with TIRF and widefield as well as an advertised confocal capabilities. The miCube has a peer-reviewed manuscript demonstrating it’s performance written by Koen Martens, Sam van Beljouw, Simon van […]
Cheap Desktop Micromills for Microfluidics
One way to make microfluidic devices, is to use a milling machine. A paper by Ali Lashkaripour, Ryan Silva and Douglas Densmore compares three micromilling machines (tiny milling machines), evaluated their accuracy, and provides methods for evaluating the accuracy of your own miromilling machines. The only machine evaluated that is still being produced, is the […]
AttoBright: A single-molecule confocal system built from a 3D-printed scaffold
The AttoBright is a 10×20 cm single-molecule confocal system capable of single photon counting and fluorescence correlation spectroscopy. The scaffolding is designed to minimize the amount of optical components needed, and make those optical components easy to install with automated alignment. A paper by James Brown, Arnaud Bauer, Mark Polinkovsky, Akshay Bhumkar, DominicHunter, Katharina Gaus, […]
