This is magnetic stand for 8 tubes PCR strip. It has been designed to be used with neodymium rod magnet Ø 3 mm, height 8 mm. They were bought on https://www.supermagnete.com . Purification with paramagnetic beads such as AMPure XP is fast and effective. Elution volume can be recovered without dead volume and residual beads. Holes have been designed to be a little bit to small in order to be adjusted with a drill. Magnets have to be pressed in their hole at the deep (~3mm) that will make them in close contact with the PCR strip, no glue is required. This is a first prototype, comments are welcome.
I have used Ngen filament because it is water and ethanol resistant.
