A New Venture into Particle Sizing

The Fisher Sub Sieve Sizer (FSSS) has been used in labs for obtaining development and QC data for over 30 years; this instrument works on the principle of particle sizing by air permeability which was established in the 1940’s and has proved to be a very reliable way for many companies to prove the batch to batch consistency of their products.

Together with John Sherwood of AstraZeneca we have developed a new generation instrument - the Subsieve AutoSizer - based on the same air permeability principles,and using HEL's accumulated skills, experience and knowledge in automation and new product development.

The FSSS, now discontinued, shown here, in comparison to the new SAS with its automated touchscreen operation.
