Rotary Rocking and Rolling
T
he HTR range can be used in the
heat treatment and analysis of
sulphide ores and metallurgical slags, and
the controlled calcination of mineral ores
and limestone.
F
or years, New Brunswick CO2
incubators have provided researchers with a reliable and easy-to-use system
for culturing cells. Continuing with this
tradition, they released the S41i CO2
incubator shaker. This shaker is designed
specifically for non-adherent cell culture
applications. It combines precise temperature and CO2 control with one of the best
laboratory shakers available.
HTR rotary° reactor furnaces combine many
of the advan tages of
fluidised bed reactors with those of
a rotary kiln. The
sample is contained in
either a 75mm × 100mm reaction chamber holding approximately 50ml
or in the larger unit, a 150mm × 200mm
700ml reactor. These quartz vessels reciprocate backwards and forwards through
an angle of 315°, at up to eight cycles per
minute. Internal vanes within the reactor
walls agitate the sample ensuring uniform
mixing and heating throughout.
Gas seals, a flow meter and control
valve allow an inert nitrogen atmosphere
to be maintained over the sample during
heating. Any exhaust gases are vented into
a removable stainless steel box that can
be vented into a fume extraction system.
Some of the customised HTR options
include the replacement of the quartz
glass reactors with Inconel reactors,
modi cation for use with argon and gas
fi
safety, and detection systems for use with
reducing gases. Carbolite routinely builds
these furnaces for use up to 1600°C.
These furnaces provide the capability
to continuously process samples or even
production quantities of material. Samples
can be fed into the furnace using vibratory
feeders or screw feeders. Designs are also
available to introduce process and collect
materials under modified atmospheric
conditions. ?

Shake your CO2 Incubator
The S41i has a unique
six-sided direct-heating
prof ile which provides
gentle convection circulation of the chamber
atmosphere for uniform
temperature control. It also
has a built-in New Brunswick shaker.
Combining their CO2 incubator and
shaker technologies creates a highly stable
environment for reliable cell
growth. When it comes to
high cell yields and viability,
and overall reliability, there
is no better solution.
The S41i incubator
shaker minimises the CO2
conumption without compromising cell
s
growth and viability. Their performance
tests show that it significantly reduces
costly gas consumption, making it better
for the budget and the environment. ?
