Description

This is the test tube photometer we describe in our recent paper:

To make it real open source hardware we put together a shopping list and building instructions which you can find on openplant.science:

Materials and methods

Both, the main body and the sleeve were printed with a Ultimaker Original + using black PLA.

It is very important to use black material because it influences the light leakage to the sensor!

Great tool! I recently wrote a term paper on engineering and described the creation of such a device. With the help of https://supremedissertations.com/ I structured my thoughts and got the maximum score.
