The spectrophotometer that we are using, the Vernier Spectrovis+, which can be found in 20.000 secondary schools, all over the world. It is created for 1cm × 1cm × 3 cm cuvettes, but our samples aren’t big enough to fill one of those. To solve this problem, our task was to design the model of a cuvette holder, which we can print in 3D. We offer to any team requires to send 3D painting information. Please contact us at our official e-mail address!

To do so, we had taken the following steps:

  1. To measure the distances properly, we used a vernier caliper, and an endoscope.
  2. By counting the pixels on the photos we had taken with the endoscope, we were able to calculate the real measurements of the cavity of the spectrophotometer.
  3. With the acquired measurements, we made a prototype in FreeCAD.
  4. We saved our finalized blueprint as a wavefront file.
  5. Then we could easily print the desired part with the 3D printer in the school.

Since the first try and product were unsuccessful, we had remodel it and repeat the steps mentioned before. Luckily, the second creation fit like it was hoped to.

There are two main advantages of this part to mention. Firstly, it won’t produce that much pollution to the environment. As we lower the capacity of the samples, we produce less pollution at the end of the experiment. Secondly, we can definitely declare, that it is much cheaper and has more opportunities in usage in life. Considering this fact, that it costs less. It is obvious that it will spread in global institutes more rapidly because it will be affordable for much more establishments around the world. This way we can measure the fluorescence of a hundred times larger number of samples than if we measured in cuvettes.
