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
