Capillary Condensation Flow Porometer is fully automated.

Dec 16, 2008

Passing vapor through sample held in sample chamber, PMI capillary condensation flow porometer measures pore size by pressure at which vapor condenses into pores, and determines pore distribution from vapor flow rate due to small imposed pressure gradient. It measures pore diameter of nanopore samples without using any toxic materials or extreme pressures and temperatures. Unit is suited for... Read More

Porometer tests filter materials.

Mar 14, 2002

On-Line Multi-Chamber Porometer performs tests on filter media without need to cut out sample. It can determine bubble point, mean flow pore size, pore distribution and gas permeability, including Gurley and Frazier permeability. Filtration medium simply slides through sample chamber. Tests can be performed in less than 10 min on production floor, and tested material is not damaged in any way.... Read More

Porometer determines volume without using mercury.

Nov 27, 2001

Capillary Saturation Porometer determines pore volume and measures liquid permeability. For volume, sample is soaked in liquid that spontaneously fills pores. Pressure of non-reacting gas on top of sample is increased to displace liquid from pores, and pore volume, diameter, and volume distribution can be computed. To measure liquid permeability, pressure is increased, and permeability is... Read More
