Whitehouse Scientific Ltd

Whitehouse Scientific has been producing precision glass microspheres for calibration for 24 years and is the highest ranking European certification laboratory for primary methods of particle size analysis.

Having filled over 1 million bottles using a unique 100 stage spinning riffler system, we are now the world's leading manufacturer of single-shot glass microsphere standards.

The references, nearly all NIST traceable range in size from 0.1µm - 5.0mm and are available as single sizes or broad distribution standards.

Filter apertures between 3 and 1000 microns can be traceably measured through NIST references using a unique calibration procedure.
