Final Design Solution

Final Design Solution: Fluid Distribution

• Reservoirs for each fluid solution

• 3 Peristaltic pumps to drive fluid flow and 1 air pump

• 3 Fully primed manifolds for each fluid solution ( 1 inlet to 10 outlets)

• Check valves at the end of every outlet before a coming together at the column

• Combiner uniting 1 outlet of every manifold and air into a single new outlet (4 inlets to 1 column outlet)

• Manual end plugs to stop flow when fewer than 10 columns are being washed, along with electronic selection

Final Design Solution: Control Interface

• Main Power Switch (On/Off)

• 4 Momentary Push Buttons (Manual Priming for Individual Fluids and Air)

• 2 7-Segment Displays (Process Time + Column Selected/Process Label)

• 3 Push Buttons (Start, Stop, and Reset)

• 1 Push Buttons (Looped +1 Column Selection)

Final Design Solution: Component Packaging

• 3 Pump Mounting on Bottom Base Plate

• 3 Manifold Mounts (Outlets facing up)

• Tiered Perforated Tray (To support tubing upright)

• Tiered Tube Rack (To hold tubes at the same height)

• Column Holder Tray (Slip fit for columns to be held during the process)

• Filter Paper Tray (Used to collect final wash sample)

• Microcontroller and PCB Space (Fluid-resistant enclosed area)

• Button Control Board (User display and controls)
