The 4" ID conflat 6-way spherical vacuum chamber is a high-quality vacuum chamber made of stainless steel. With a 4" inner diameter and 6-way spherical design, this chamber provides a large volume for vacuum experiments while optimizing space efficiency. Ideal for research and industrial applications, this vacuum chamber ensures a reliable and controlled vacuum environment for precise measurements and simulations.

Please look at the way the inner edges were done. This is a more expensive was and I believe it is done so there is less chance for power feed through thru issues.

100 in handling is for insurance.
