[DIYbio] Re: DIY tube holder for vortex mixers

Why couldn't you use the foam block on a vortexer idea that I posted
about? I see that in the picture the tubes are horizontal, you could
just cut slots in the foam so the tubes are horizontal rather than
vertical. This would be easier than mounting an inverse dremelfuge to
a vortexer.
