You may have come across pictures of an NMR spectrometer made entirely of LEGO bricks. This is currently supported on the LEGO Ideas pages:
As of today the project has 2548 supporters and there are 135 days left to support the project. If the project receives 10000 supporters LEGO may come up with a small kit to build a spectrometer. Please consider supporting this effort.
PS: I was actually much more of a Fischer Technik guy when I grew up in Germany.
