Half of the bill of materials has been received, including the 6 peristaltic pumps, the power supply, and micro SD card. 

The peristaltic pumps are tested. These work at a maximum of 5A with 12V (seen in Figure 6) and have an average flux of 72.2 ml/min.

Pump dimensions fit well with Prototype 4.

Some details were added to Prototype 4 in order to make the base of the structure more stable as it can be seen in Prototype 5 (Figure 7). These details consisted of 3 traverse columns under the main base and several extra supports that give enough stiffness to the structure, as well as enough space to store cabling.
