SnapRack - modular, space-saving, snappy

The SnapRack system is designed to easily reconfigure your sample handling rack on the fly to suit the needs of your current task.

It fits 1.5, 2.0, 5.0, 15, and 50 ml tubes/falcons.

Whether you want to pipet a master mix from a 15 ml falcon to an array of 2 ml tubes or split your 12 samples into two groups of 6 for different treatments. The SnapRack makes attaching and detaching of modules easy (and quite fun).

You don't risk spilling or agitating the samples with the smooth snapping of the modules.

The notches and ridges in the snapping mechanism help you align the modules for a flush fit and wiggle-free handling.

SnapRacks are ideal for working in constrained spaces such as flow-hoods. Only take as many modules with you as you need. No need to place two whole racks under the hood for only a few 50 ml Falcon and 1,5 ml tubes when doing media exchanges for your cell culture.

I also use them extensively to store samples and reagents in small spaces, that would not fit larger racks, like in fridge door compartments or between the storage boxes in the freezer.

You can even use them as basic building blocks to quickly fix something in place or make an impromptu phone holder.

Printing instructions and material properties

The modules are optimized for easy printing without supports.

I recommend PETG due to its flexibility and chemical resistance. PLA works well but will make the fit much stiffer initially and get looser over time. ABS and PP are fine as well. Especially consider PP if you intend to autoclave your SnapRacks. PLA, PETG, and ABS will NOT withstand a standard autoclaving cycle.

Disinfection with ethanol or chlorine gas has been tested and works well.

Freezing in liquid nitrogen will not affect the functionality or structural integrity of the racks.

Changelog

Added tube modules with 2 and 4 rows.

Added blank versions of all modules for easier remixing.
