Measuring cell growth in style

Kinetics measurment

Knowing the speed at which cells grow on agar was immensly important throught out experimentations with different agar additives. Which is why we decided to build our own kinetics measurment system.

Camera system

Our engineering team used a raspberry camera 2 to capture the images of petri dishes. The camera is lit by our own 3D printed reflector that was painted on the inside with a barium sulfide based paint.

Petri exchange system

Also using 3D printing, we made a barrel that can hold up to five 90mm petri dishes. The barrel is powered by a NEMA17 stepper motor which is also connected to the raspberry pi using a stepper driver.
