Whitehouse Scientific, the highest ranking European certification laboratory for primary methods of particle size analysis, has launched its new PoreSizer^TM system for image analysis.

The PoreSizer^TM is a static image analysis system that measures particle size and shape, sieve meshes and filter pores using an optical microscope and high quality 1.4 megapixel camera. Specifically designed for the measurement of geometric pore sizes of filter media, the system is the culmination of a development programme spanning a number of years and provides a bespoke, transparent measurement process that is validated and fully traceable using certified...

Whitehouse Scientific, the highest ranking European certification laboratory for primary methods of particle size analysis will be exhibiting its state of the art calibration microspheres and services at FILTECH 2016 between 11-13 October in Cologne, Germany

Dr Graham Rideal, CEO of particle sizing standards company Whitehouse Scientific, will present an image analysis technique to ensure accurate, robust and reproducible particle size measurements at PARTEC 2016, the International Congress on Particle Technology (Nürnberg, Germany: 19-21 April 2016), in a paper entitled Particle size analysis – Investigating Measurement Uncertainties in the Development of a Robust Validation.

Participating in the Applications of Particle Technology session at PARTEC, Dr Rideal will speak on the challenges of proving that the imaging technique employed measures the correct dimension constantly and consistently throughout the analysis process. His paper investigates methods to ensure the validity of results and addresses all the elements that could be challenged in proving an unbroken link to the international definition of the...

World renowned standards company, Whitehouse Scientific, will exhibit its unique range of filter calibration products and services on Booth A1212 at the 12th World Filtration Congress (Taipei International Convention Center, Taiwan: 11-15th April 2016).

Dr Graham Rideal, CEO of Whitehouse Scientific, will also present a paper on the latest developments in wet challenge testing to accurately define pore size in a filter, to an audience of scientists, engineers and practitioners operating in the filtration field. Dr Rideal™s presentation, Latest Developments in Wet Challenge Testing, will highlight the importance of being able to accurately measure maximum pore size in filters across a wide...

Whitehouse Scientific, a world-renowned producer of calibration microspheres, helped celebrate the landmark 50th anniversary of The Filtration Society’s annual international conference and exhibition as an established and major sponsor.

Taking place at the Riverside Innovation Centre, Chester, UK, over  100 international visitors joined the two day event, which featured  the presentation of  over twenty technical papers by international industry experts and a ‘full to capacity’ trade exhibition, showcasing the latest technologies in wet and dry filtration. Dr Graham Rideal, CEO of Whitehouse Scientific and science correspondent for The Filtration Society, said, “The conference...

Dr Graham Rideal, CEO of Chester based calibration standards company Whitehouse Scientific, has once again serenaded patients, visitors and staff at the Countess of Chester Hospital by playing the saxophone and clarinet to raise funds for the Trust's Relative Comfort Appeal.

Through his musical performances, Dr Rideal, a former patient at the hospital, has now donated over £3,000 to support this appeal. The Trust has raised in excess of £300,000 which will help provide overnight accommodation and counselling rooms for friends and family of critically ill patients. "The hospital has helped me through both colon and liver cancer and I owe my life to the doctors who treated me. I know how much loved ones are...

Dr Graham Rideal, CEO of Whitehouse Scientific, will present a keynote lecture at FILTECH 2015 on the topic of ‘Measuring Filter Cut Points and Pore Size Distributions by Challenge Testing’.

The conference takes place from 24-26 February in Cologne, Germany, where Whitehouse Scientific is also an exhibitor, and Dr Rideal’s lecture is on Wednesday 25 February at 9.00 am. Challenge testing is a direct or primary method for measuring pore size in filters, which involves collecting and measuring the challenging particles that pass through the filter. It has advantages over secondary methods, such as porometry, which rely on theoretical predictions...

In March 2014, Chester (UK)-based calibration standards specialist Whitehouse Scientific continued their co-sponsorship of the Philippines national team in the second Street Child World Cup held in Rio de Janeiro, Brazil.

During the 10-day tournament, Dr Graham Rideal, CEO of Whitehouse Scientific, was able to catch up with one particular team member from the Philippines who he had met previously while undertaking voluntary work in Manila. Crystal was a member of the Philippines girls team which beat South Africa, El Salvador, England and Mozambique before losing by just one goal to host nation Brazil in the final. Dr Rideal, takes a very active role in working with street children in the Philippines. “The highlight for me was meeting Crystal again. She was born in a municipal cemetery and was raised on the street, scavenging for food and shelter,”...

For the second successive time, Chester (UK)-based calibration standards specialist Whitehouse Scientific is sponsoring the Philippine’s national team at the Deloitte Street Child World Cup.

Whitehouse Scientific CEO Dr Graham Rideal has for many years been involved in projects to support young people in the Philippines and in 2010 Whitehouse Scientific was one of the inaugural team sponsors involved in the Deloitte Street Child World Cup.Street children representing up to 20 countries from all five continents will kick off a ten-day tournament in Rio de Janeiro, Brazil, on 28 March 2014. Not only will they play football but they will also be raising awareness towards gaining rights for street children all over the world....

More than 80 delegates from several countries attended the most recent of the Filtration Society’s popular two-day technical meetings.

 ‘Filter Media 6’ was held in Chester, UK, on 5-6 November 2013. The one-day conference on 6 Nov focused on ‘filter media’ and was preceded on 5 November by an educational course on ‘Media for Gas and Liquid Filtration’. Billed as the most comprehensive introduction to filter media anywhere in the world, the short course was presented by filtration expert Professor Richard Wakeman and consultant engineer Dr Steve Tarleton....

Whitehouse Scientific is once again a major sponsor of The Filtration Society’s annual international conference and exhibition, returning on 5-6 November 2013 at the Mercure Chester East Hotel, Christleton, Chester, UK.

This year the main one-day event focuses on ‘Filter Media’ and will be preceded by a ‘Media for Gas and Liquid Filtration Course’. Attendance at Filtration Society meetings is open to everyone - members, non-members, UK and non-UK delegates. The full conference programme, registration and exhibition details are now available.
