Summary

Methodologies such as Polymerase Chain Reaction (PCR) can require sampling from many standard sized microtubes to a commonly used 96-well or 384-well format. Many downstream methodologies align with this 96 well format, yet the default tube holder arrangement for Eppendorf tubes does not allow for multichannel usage. This can lead to tedious and error prone workflows when there are many tubes that require sampling.

This is a tube rack that allows for multichannel sampling of tubes into a 96 well format. Staggering tips on a multichannel allows for sampling from adjacent Ependorfs into every-other 96-well tube, or every 4, 384-well tubes. Zig-zag organization schemes of samples and various other strategies allow for a wide variety of applications with an increased throughput while also providing additional redundancies for common errors such as skipping or repeating samples.

Notes:
This STL is one file removed from the final version and does have the conical bottoms. (will update when able)

Printed face down on mirror surface with minimal padding and 60C heat bed.

Note: The mirror ended up being a single use item as some shards of glass came free with the build, but were able to get cleaned off with some care. The shiny result was worth the effort.

Post-Printing

I had to clean shards of mirror off the tube face, but aside from that. no sanding or removal of supports were required with the final version of this print.
