Whitehouse Scientific Ltd

The company was founded by Dr Graham Rideal. He left ICI in 1983 where he worked as a senior research scientist. Here he headed a large team which embarked on pioneering work in the field of Nanotechnology. It was his fundamental studies of Angstrom sized mineral platelets that highlighted the need for improved measurement techniques and calibration standards for these ultra-fine platelets. The laboratory now manufactures one of the largest ranges of glass calibration microspheres available today covering sizes from nanometre to millimetre. Whitehouse Scientific is unusual in that it is research rather than sales driven as evidenced by over 60 technical papers and patents by Dr Rideal. A unique feature of the particle size standards is that they are packaged as dry samples for ‘single shot’ analysis so minimising operator sub-sampling errors. Over 1 million single shot bottles have now been produced for almost every particle sizing instrument. Recent years has seen an exponential growth in the use of the standards for calibrating filters. Innovative technology now enables filter performance to be unambiguously measured with results traceable in international standards of length. Sadly Dr Rideal passed away in September 2020. Whitehouse Scientific is now headed by his two daughters, Lauren and Bethany (who have nearly 30 collective years at the company).
