iPore Capillary Flow PorometeriPore Capillary Flow Porometers are used for R&D and quality control in industries worldwide such as filtration, nonwovens, pharmaceutical, biotechnology, healthcare, household, food, hygienic products, fuel cell, water purification, and battery to provide pore size distributions of through pores in materials. Samples often tested include filter media, membranes paper, powders, ceramics, battery separators and health care products.
Capillary Flow Porometryi Pore is based on capillary ﬂow porometry, where a non toxic wetting liquid is allowed to spontaneously ﬁll the pores in the sample and a non reacting gas is allowed to displace liquid from pores. First the largest pores will get emptied, as they require lower pressure than smaller pores. As the pressure is increased, more and more smaller pores are progressively emptied. The pressure and ﬂow rate of gas through the emptied pores provides the through pore distribution. The pressure at which through pores empty is inversely proportional to the pore size. Through pores are the pores connected from one side of material to the other side. i Pore capillary ﬂow Porometer measures the pore throat diameter, which is the most constricted path of the entire pore. Bubble point, pore size distribution, pore flow distribution and density can all be calculated.
i Pore PorometersThe i Pore is an advanced capillary ﬂow porometer series, which yield accurate and reproducible data. The i Pore series porometers require minimal operator involvement with considerably small test durations. The i Pore porometers are designed for linear turbulence free ﬂow of test gas, the pressure is measured closed to the sample thereby minimizing the correction in differential pressure measurement. i Pore series has six different models to suit varying pore size ranges and ﬂow rates. Each model has appropriate measuring system with pressure control, sensing, acquisition and data analysis software, sample holders, various unique upgrade options, accessory and consumable kit.
