Capillary flow porometers: Porometer 3G

Composition of solids

“ No need for calibrations: saving operator time and effort The pressure sense line in Porometer 3G instruments measures the pressure directly at the sample, and is therefore unaffected by changing flow rates. In contrast, conventional capillary flow porometers measure the pressure at some fixed point prior to applying the sample, and use sample-specific flow path calibrations to predict the pressure at the sample. Because the amount of airflow within this path affects the pressure gradient that exists, each sample type requires a calibration to be performed and applied. The unique design of Porometer 3G eliminates the need for calibrations. This means much less effort and ultimately more accurate measurements. Automatic pressure regulation ensures ideal measurement conditions every time Porometer 3G instruments use an intelligent pressurization routine designed to ensure results within equilibrium throughout the measurement. This routine eliminates the problems that come with conventional systems, due to the fact that measurements made with a constant ramp rate, which is too fast, provide smaller-than-correct pore sizes, as they don’t allow enough time for equilibrium to be achieved at each pressure data point. Conversely, similar measurements made too slowly accentuate the effects of wetting fluid evaporation, providing larger-than-correct pore sizes. Porometer 3G units automatically regulate the pressure - which leads to accurate results independent of the settings. Complete through-pore size distribution for the full set of data Porometer 3G makes all flow measurements on a single flow meter, and thus obtains a continuous account of through-pores present in your material. This includes the crucial region between the maximum and mean pore sizes. Capillary flow porometers that switch measurement devices after the bubble point is reached run the risk of missing a portion of this data. You can rely on Porometer 3G to deliver a complete data set. Wet-then-dry, dry-then-wet – you choose Capillary flow porometry measurements involve both a “wet curve” (the flow resulting from the expulsion of wetting fluid from pores at different pressures) and a “dry curve” (the flow through the material over the pressure range of the measurement when wetting fluid is present). Measuring wet-then-dry is much simpler for the operator and does not involve opening the sample holder in the middle of the experiment. Dry-then-wet measurements remove concerns about potential effects on the sample during the creation of the wet curve. Both measurements are available on all Porometer 3G instruments. You can enjoy the workflow ease of wet-then-dry measurements and still have the option to perform dry-then-wet measurements when samples warrant it. Adapts to the wide range of sample requirements in your lab All Porometer 3G instruments have the ability to use different shape factors and different fluids in order to develop a test method specifically catered to your sample measurement needs. In addition, their design is perfect for adapting to samples of various sizes and shapes via external holders for use with hollow fiber, solid piece, or rigid tubular configurations. ”

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.
