Customer Requirements
Importance: 1=Essential, 2=Customer Want, 3=Preference
![Page 13: P15080: Flow Culture System Multi-Disciplinary Senior Design Problem Definition Review September 11, 2014 Collin Burkhart – Lead Mechanical Engineer Katelyn](https://reader035.vdocument.in/reader035/viewer/2022070413/5697bfce1a28abf838ca98df/html5/thumbnails/13.jpg)
Essential Customer Requirements
Sterility, Temperature, pH
![Page 14: P15080: Flow Culture System Multi-Disciplinary Senior Design Problem Definition Review September 11, 2014 Collin Burkhart – Lead Mechanical Engineer Katelyn](https://reader035.vdocument.in/reader035/viewer/2022070413/5697bfce1a28abf838ca98df/html5/thumbnails/14.jpg)
Constraints
● It is assumed that the flow culture system will be using only animal endothelial cell lines
● This system may need to sit in an incubator to control temperature, media pH, and relative humidity
● Chamber that holds cells needs to fit on defined microscope stages
● System must be sterilized by autoclave● Budget of ~$1550

Benchmarking● Perform cell culture in BME Lab with Dr.
Bailey● Research and contact representatives of
current companies that market cell culture flow devices
● Confer with Dr. Gaborski and Dr. Man

Top RisksBudget: ● Materials too expensive
Schedule: ● Team member delays● Unexpected labor hours
Technical:● Unable to keep materials sterile● Material malfunction● Pump inadequacies● Lack of knowledge in electrical engineering spectrum for sensor
configuration
