This testing station will hold it all. It holds 4 Hanna Testers with all the things that go with them. Small holes next to the testers are for the syringes, so you don't mix them up for which test they go with. Spots in the front will hold the glass test tubs for both the Hanna tests and the API tests. Test tubs are held tightly to be stable for adding the chemicals or water. The slot behind the front holes are for the titration cards or directions for the test. Pegs and cup are for proper drying of the test tubes and caps.

This is still a work in progress, but I have been using the prototype for months. The original print was also printed on my CR-6se. There will be more and updated models to come for this project.
