Various Expanded Spherical Cubes, with 6 CF, 4½ CF, 2¾ CF, and 1a CF ports(approximately 0.25x scale)

THE EXPANDED SPHERICAL CUBESThe Expanded Spherical Cubes are similar to Spherical Cubes but with an expanded diameter to provide a larger number of ports in a cubicalsymmetry and a larger internal workspace. They consist of hollow spheres intersected by six sealing surfaces forming the cubical faces,with additional
optional smaller sealing surfaces on the corners and edges. Each 6 CF, 4½ CF,or 2¾ CF sealing surface has Grabber Grooves for internal mountingof apparatus.
CUSTOM EXPANDED SPHERICAL CUBES with custom port configurations are available, consult Kimball Physics Engineering.

2¾ Multi-CF Expanded Spherical Cube
MCF275-SphCube-C6A8THE 2¾ CF EXPANDED SPHERICAL CUBE
The 2¾ CF Expanded Spherical Cube is a small Multi-CF UHV chamber witha maximum of 14 ports in a cubical symmetry. It consists of a hollow sphereintersected by six 2¾ CF sealing surfaces and eight 1a CF sealing surfaces
on the corners. Each 2¾ CF sealing surface has a pair of Grabber Grooves.
The 2¾ Expanded Spherical Cube has a 3.300 inch spherical inner diameterand a 4.582 inch outer diameter (3.680 inch between the 2¾ CF ports).
