control breakthrough with launch of Redostat
innovative product guaranteed to assist scientists in fields as
diverse as medicine, mining and the environment, by controlling
and recording the oxidation-reduction potential in experiments will
be launched at the International Biohydrometallurgy Symposium, 25
29 September 2005.
Redostat system maintains the redox potential, a master variable
in many chemical and industrially important reactions by using electrical
current as an oxidising or reducing agent.
to specifically address the problems of scientists that arise with
variation of redox potential during experiments, Redostat
has chemical, environmental, biochemical and biotechnology applications,
specifically in areas such as mineral leaching, bacterial growth,
acid mine drainage, and medical studies.
units have already been sold to amongst other: A & M University
in Texas, University of Cape Town and Mintek. Researchers at A &
M University in Texas are using Redostat to study the growth
of bacteria on Martian soil.
design has been published and the results from this design have
led to the most clear and thorough information on the role of bacteria
in the leaching process to date.
Frank Crundwell, inventor of the Redostat says: "At last
scientists can maximise their time in the lab by having access to
a reliable experimental apparatus which significantly increases
the accuracy of experiments, particularly for the careful study
of critical reactions that are dependent on redox potential. What
is exciting for the industry is that Redostat will enable
researchers to conduct unique experiments, charting unexplored worlds!"
Redostat package incorporates instrumentation and control
systems in a compact bench unit. Other features include: a computer
control and an experiment chamber for control of redox potential,
pH control, temperature control, agitator speed indicator, dissolved
