Masterwave BTR Kilolab microwave

The Masterwave BTR Kilolab microwave is NOW AVAILABLE for booking in our laboratories.

SabiNano (Pty) Ltd is one of the few companies in South Africa that owns the all-new Masterwave BTR benchtop reactor. The reactor, for the first time is transferring the microwave synthesis to the kilolab. Lab productivity of up to kilogram amounts per day is made possible. The benchtop reactor’s magnetically driven paddle stirrer provides independent stirring regimes for individual content. Due to its rising-sensor temperature measurement technique, Masterwave BTR features the high temperature accuracy required for direct method transfer from any smaller microwave device. This upscale synthesis microwave can now be booked for utilization by both industry and academic researchers. Contact us on info@sabinano.co.za or call (011)709 4798 to make further enquiries about the microwave’s offerings, booking procedures and pricing.

Professor Neil Coville, PhD

Neil Coville obtained his B.Sc. (Hons) and M.Sc. degrees at the University of the Witwatersrand (Wits), Johannesburg, before proceeding to McGill University, Montreal in 1968 where he obtained his Ph.D degree (1973). After post-doctoral work at Harvard University he returned to Wits in 1976. He worked his way through the ranks in the School of Chemistry, from lecturer to Chair of Inorganic Chemistry before becoming an Emeritus Professor. He is still a member of two DST-NRF Centres of Excellence (Catalysis; Strong Materials) and maintains an active research group. His research work is focussed on carbon chemistry – synthesis and applications - and this has led to many studies on the shaping and doping of carbons. The applications include the use of the carbons as catalysts supports (e.g. in Fischer-Tropsch catalysis) and for use in sensors and solar cells.
