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