About us

Gearing Scientific Ltd

Gearing Scientific was formed in 1995 to specialise in certain areas of polymer and other materials analysis, based on >25 years experience of selling and supporting polymer analysis apparatus worldwide by its MD, John Gearing.

We specialize in thermal contract testing in particular in: Thermal conductivity up to 250°C mean T for rigid solids, or less for liquids and softer solids, using 6 off Lasercomp Inc apparatus (now TA.) 2. Thermal expansion up to 1000°C on a pukka TMA by TA Instruments. 3. DMA from <<-100°C up to >>300°C for solids and composites. 4. We can also do DSC and TGA but sub-contract these out so that the very fast delivery cannot always be confirmed immediately!

Finally we offer narrow GPC/SEC calibration standards with discounts for Universities, and other special polymers with particular end groups for research and pharmaceutical applications such as drug delivery. The main 2 suppliers are: www.polymersource.com and www.ampolymer.com both from North America. (For 20 years I was involved with Du Pont and then Polymer Laboratories Ltd in selling GPC / SEC systems etc.)

John Gearing is a member of the composites processing association, the plastic consultants network (pcn), SAMPE, the Nottingham University Composites Club, and the Institutes of Materials, Physics and Mechanical Engineers.
