Surface Area and Pore Size Analyzer is designed to satisfy busy laboratory needs for high analytical throughput, without sacrificing precision, flexibility or cost-effectiveness. Four simultaneous and independent analysis ports remove the limitations of single dewar systems allowing samples to be started as soon as previous measurements are completed. A dedicated transducer has been provided for measurement of Po (adsorbate saturated vapor pressure), so that continually measuring Po does not slow down analysis capabilities. The new BET “QuickModeTM” provides high throughput industrial materials characterization labs the ability to process samples at dramatically improved speeds. This measurement flexibility has never before been available in such a compact and cost-effective package.
