Poseidon is a well documented open source microfluidics and imaging system consisting of a set of three DIY syringe pumps for $180 and a compatible microscope for $220. Poseidon is documented in a paper on BioRxiv by A. Sina Booeshaghi, Eduardo Beltrame, Dylan Bannon, Jase Gehring, and Lior Pachter . In the paper, the system is benchmarked to Harvard Apparatus […]
OpenFlexure Block Stage: 3D printed sub-micron mechanical precision
OpenFlexure Block Stage is a 3D printed flexure translation stage with sub-micron mechanical positioning. You can get the files to build it on GitHub. The project is 3-axis, short travel, high accuracy spinoff from the stage of the amazing OpenFlexure Microscope which we still haven’t covered, but we thought this stage deserved a post of its […]
Surplus Chemical Programs
At some universities, Chemical Surplus Programs provide an official channel to leave and take chemicals stocks. If your lab has a chemical that you aren’t going to use up, you donate it and save space. If your lab needs a chemical, you can check the surplus program before purchasing it and save some money. Below […]
Smartphone spectrophotometer for less than $6
We’ve covered smartphone florescence spectroscopy before, and we also have a post on building your own Lego spectrometer. In a similar vein check out a dedicated spectrophotometer detailed in a paper by Vasco Pereira and Bill Hosker. Maybe. The paper covers a 3D-printed version and teases a Lego constructed version. Either way, you have a […]
UV Transilluminators and Imaging on the Cheap
We’ve written about Gel Electrophoresis before, the punchline of which was that MiniPCR has good gel electrophoresis and imaging system for just $350. However, that system is for blue light. If you are trying to image faint bands of DNA stained with ethidium bromide you need a light source on the low end of 300 […]
