Over engineering a tube holder as far as it will go. Introducing the modular tube rack! 

Looks fun. I'll definitely try some.

this is an excellent idea and use of the gridfinity platform!

Never thought I'd see gridfinity in the lab, great design.

I rhink the lights open up lots of cool ideas! Imagine a test / manufacturing procedure thats guided by light based work instructions.

This is actually a great solution! I am a bioengineer and usually even when i make simple assays I end up using two different holder, and their size are minimum 8x2. This makes me laugh because sometimes their duty is just to hold one falcon and 3 eppendorfs.

one of the biggest issues with PCR is cross contamination. in many cases you do want that physical separation. while you are just messing around in a home lab, much of this will be fine, but it isn't any good for working in an actual lab. you would have to unlearn all the bad habits. this is more than likely why a solution doesn't already exist, because it wouldn't be commercially viable to produce stuff just for a home lab that doesn't follow best practices for an actual lab.

Woo! More gridfinity!

Excelent idea. I work in a lab too, and the racks are a problem
