Capillary Flow Porometers:
Porometer-3G
Get the most easy-to-use capillary flow porometer available
The Porometer 3G series of capillary flow porometers delivers accurate and repeatable through- pore size distribution results, typically within only 30 minutes for any sample. As these units do not require the constant calibration of the pressure gradient within the flow path, they make the process of multi-instrument alignment much simpler. Sample throughput is greatly increased by their simplified operation and measurement speed. Three distinct models are available to fit the specific air permeability and pore size characteristics of a wide range of membranes and filtration media.
