Patent ID: 7146999

Claim:
A modular fluid handling device comprising a series of blocks, each having a block top face, an opposing block bottom face, and a series of block sides therebetween, wherein: a. the block faces are shaped as tessellating regular polygons, b. each block includes a central bore extending between the block faces, wherein the central bore has a polygonal cross-section, whereby an insert having a complementarily-shaped polygonal perimeter may be non-rotatably fit within the central bore; c. each block includes channels extending between opposing block sides, wherein the channels intersect at the central bore and extend therefrom at equal angular intervals; wherein: (1) the blocks may be arrayed together in side-to-side abutting relationship to form a two-dimensional array of blocks wherein abutting block sides have their channels coaxially aligned; (2) the blocks may be arrayed together in face-to-face abutting relationship to form a stacked array of blocks wherein abutting blocks have their bores coaxially aligned.
