A new spin-off of Click Chemistry Tools called Fluoroprobes, is creating generic versions of fluorescent dyes. Our lab recently switched from buying Alexa Fluor® 647 NHS Ester from Thermo Fisher ($339/1mg) to the generic AF 647 NHS Ester from Fluroprobes ($139/1mg). Saves us quite a bit of $$$. We use this dye to label proteins […]

ManufacturingReports.com Helpful reviews of PCB manufacturers
On this website, at least 20 of the Do-It-Yourself pieces of research equipment that we have covered involve Printed Circuit Boards (PCBs). We once suggested using EasyEDA to design and order these components, and were told over time that we were wrong, and that you should download KiCAD and use that instead. But this is […]
More DIY Optical Shutters
Several months ago we wrote a short write up about making a cheap optical shutter out of a hard drive disk controlled via Arduino. Since then we have had two Uniblitz shutters fail. We have now seen 6 Uniblitz shutters seen fail relatively quickly, with different users and different use conditions, over three labs. Even […]
ODX: $25 For Turbidity (OD) Measurements
A couple of weeks ago we covered MicrobeMeter. At $420 it’s not exactly pennies, but you can buy it pre-built or as an easy DIY kit. For a similar price, we also covered a user friendly low-cost turbidostat. But now we are aware that there is a cheaper option. A much cheaper option. Ganga C. […]
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 […]
