Patent ID: 6935159

Claim:
A sample chamber for a centrifugal permeameter for testing permeant conductivity of a porous sample, said sample chamber comprising: a rigid outer sleeve; a resilient inner sleeve mountable over said sample and within said rigid outer sleeve; fluid inlet means for introducing fluid between said inner and outer sleeves; sealing means acting between said inner and outer sleeves for maintaining said fluid therebetween; a porous top member for mounting over a top face of said sample and supplying said permeant to said sample, said top being movable with said sample to maintain a radially outward permeant force on said sample as said sample is being spun in said centrifugal permeameter; a permeant supply for supplying said permeant to said porous top; and, a permeant accumulator for receiving and accumulating permeant which has passed through said sample.
