Open Spin Microscopy
Awhile back we talked about OpenSPIM, which has a great step by step tutorial on how to make a light-sheet microscope. In the same vein there is Open Spin Microscopy, a website with several DIY light sheet microscopy projects including a much simpler optical tomography design. The website can be a little tricky to use, […]
Paperfuge: A Paper Centrifuge for QBC Capillary Tubes
Using some card stock paper, a braided fishing line, some PVC pipe (or wood), and drinking straws with acrylic a team at Stanford proposes a basically free alternative to QBC centrifuges with comparable performance. To paraphrase from the paper: “The hematocrit results obtained in 1.5 mins on the paperfuge are comparable to the results obtained […]
A Magnetic Tube Rack for DNA Extraction
Gabriel tweets: ” @LabOnTheCheap We build a magnetic tube rack for DNA extraction and wanted to share the stl file to all interested in 3D-printed lab equipment. “ And here’s the link to the STL file hosted on the NIH 3D Print Exchange. It’s crazy that these devices are often sold for hundreds of dollars. […]
Waldoes (3D Printed Micro-manipulators)
Need a micro-positioning device for your magnetic tweezers or dissections? Check out open-labware’s 3D-printable micromanipulators. These seem to be based off unmotorized models by BackyardBrains which are also open source in design but can be bought directly. That latter option isn’t cheap though, at around $100 a pop. Here’s why I call them Waldoes.
