In a follow-up to my all time favorite post, Protein Purification on a Budget: Technical Tuesday, today we are covering a design for a fraction collector for <$100. In their recent preprint, Low-cost, scalable, and automated fluid sampling for fluidics applications , A. S. Boosehaghi, Y.A. Kil, K. H. Min, J. Gehring and L. Pachter […]

A low cost microfabrication toolbox
If you are interested in working with microfluidics and are having difficulty getting started, check out a paper by Jérôme Charmet, Rui Rodrigues, Ender Yildirim, Pavan Challa, Benjamin Roberts, Robert Dallmann, and Yudan Whulanza. The paper describes cheap solutions to several chamber fabrication techniques including photolithography, micromilling, 3D printing, xurography (knife cutting) and screen-printing. The […]
A $400 SLA-3D-printed peristaltic pump for multi-channel systems
The FAST Pump is an elegant, low cost, small, and easy to fabricate alternative to commercial peristaltic pumps which will cost you between $140 to $400 depending on quality and DIY considerations. Detailed instructions on how to make the device are covered in this paper by Alexander Jönsson, Arianna Toppi, and Martin Dufva . Lab […]
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 […]
$2 microfluidic pumps made of latex balloons and stockings
Generally, microfluidic systems require an external pump system to operate. Self-sufficient microfluidic systems are microfluidic systems that have all the components they need on the microfluidic device itself. This is a key concept in lab on a chip designs (the devices from whence this website puns its name). A paper from Peter Thurgood, Sergio Suarez, […]
