Sorry for no updates! Here is where we are at now:
Finalization for design of the capper is underway. We are starting to set up a prototyping model for the end of the capper that will actually interact with the cap. We are using PVC to test different diameters.
We have yet to actually have a cap. All the materials for the mold are in, but it still needs to be made. Then we can inject plastic in order to actually get a cap and test it.
The idea for the vortexer is underway using a dc motor to spin a rubber disc which with vortex the tube by use of friction.
