Egg vacuum cups are double-bellows cups with a conical lower lip designed to gently grip eggs in a wide range of sizes.
The lower bellows and lip collapse and nest inside the larger upper lip to provide stability under shallow vacuum levels that will not harm the egg shell.
Common applications are sorting, incubation, rejection, or inoculation of eggs.
Egg vacuum cups come in one material: brick-red, 30 Shore-A silicone rubber.
