Objective● Primary goal:
○ Develop device safely removes embryo of a quail egg for cancer research■ Extraction rate > one egg/ minute■ High success rate ~90% (current: ~50%)
● Adjustable for varying egg sizes● Should be cleaned weekly and maintained annually● Easily operated

Results
Customer Feedbacks
● Main concern: sanitary!○ Components withstand
high temp. ~ 120 C○ Must conform to
biosafety level 2 requirements
Hirayama sterilizers hve 50
Other Issues
● Vacuum suction○ Albumen into valves○ Piston not providing proper suction
● Leaks in vacuum seals○ Porous 3D printed parts
Next step● Vacuum
○ Additional valves--change suction to compression○ Filter or trap in case of egg breakage (e.g. syringe filters)
● Puncturing device○ Design/ materials: carbon steel○ Incorporate with handheld device
● Material selection○ Suction cups: silicone (withstand high temp.)○ Components: acrylic
