Whitehouse Scientific has a unique method for determining the cut point of filter media.

Using specially prepared, precision glass microspheres to challenge the filter, it is possible to measure filter efficiencies within micron resolutions.

The Whitehouse Scientific method uses narrow particle size distribution standards and covers pore sizes from just a few microns to more than 600 microns. Results are highly reproducible and traceable to international standards, NIST for example.

We produce a comprehensive range of glass microsphere standards for calibrating all methods of particle size analysis from laboratory sieves to the most complex laser diffraction analyser. From single sizes to 10:1 ratio blends, they come in single-shot bottles to reduce analyst sampling errors. Whatever the particle sizing method, we have the perfect solution.
