The working face of the suction cup is made of elastic, flexible material and has a curved surface. [3] When the center of the suction cup is pressed against a flat, non-porous surface, the volume of the space between the suction cup and the flat surface is reduced, which causes the air or water between the cup and the surface to be expelled past the rim of the circular cup.
The self-sealing suction cup is a suction cup that exerts a suction force only when it is in physical contact with an object. Unlike most other suction cups, it does not exert any suction force when it is not in contact with an object. [1] Its grasping ability is achieved entirely through passive means without the use of sensors, valves, or ...

A Büchner flask, also known as a vacuum flask, [1] filter flask, suction flask, side-arm flask, or Bunsen flask, is a thick-walled Erlenmeyer flask with a short glass tube and hose barb protruding about an inch from its neck.
For micro-suction tape, the necessary force is proportional to the attachment surface area. Compared to a suction cup, the force is smaller for the tape (assuming the same attachment surface area) because only a portion of the surface area contains craters that form vacuum chambers, and the maximal force factor is determined by this portion.
