THE 1a CF AND 2¾ CF SPHERICAL CUBESThe MCF133-SphCube-A6 Spherical Cube is a six port Multi-CF miniature UHV vacuum chamberconsisting of a hollow sphere intersected by six 1a CF sealing surfaces. The MCF275 Spherical Cubes
are six to twelve-port Multi-CF miniature UHV vacuum chambers, consisting of hollow spheres
intersected by four to six 2¾ CF sealing surfaces and/or zero to eight 1a CF sealing surfaces. Interiorspace has been greatly increased over previous designs. Each 2¾ CF sealing surface has one pair ofGrabber Grooves. Two to eight external tapped holes allow mounting without utilizing the gasket
crushing bolts. The holes may also be used to attach small heaters for chamber bake-out.
