Chemistry modules are single or multi-channel and can accept
up to 3 heating baths and a UV digestor. Manifolds are interchangeable
and cooling fans are fitted for 37°C baths when high temp
baths are adjacent. Spillage and overflow drains avoid seepage
of liquids to electrical controls. A see-through protective cover
prevents damage to manifold glassware.
A variety of chemistry manifold types and combinations are offered.
1 to 4 channel chemistry bases accommodate high performance UV
digestion, high and low temperature dry heating baths, distillation
heads, Anidet components and cadmium columns. All controls are
housed and conveniently positioned away from liquids at the front
of the case. A see through cover allows the operator to view
the temperatures and indicator lamps. Each base has a fixed number
of acrylic manifold platens which have safety spillage galleries
that couple to a common waste manifold. Any overflow or leakage
of liquid materials passes out through the rear of the unit.
An acrylic cover is supplied with each base to protect the glassware.
has always been an important feature for the SFA 2000 chemistry
manifolds and systems generally, so assembling suitable distillation
components to mount directly on to the SFA 2000 chemistry base
is a natural progression.
The distillation head operates at temperatures up to 165° C
controlled to +/-0.1° C. A stable temperature is reached
within 5 minutes of start-up. The dry bath heater uses a standard
glass coil (approximately 6ml volume) with a pre-set digital
temperature control adjustable from 37° C. The manifold components
are situated close to the distillation head. This creates operating
convenience and considerable saving of space.
The unit avoids the use of "bulky" oil baths and lengthy
glass connections associated with other analysers. When fitted
to the 4-channel chemistry base the interconnection, for example,
to a cyanide chemistry on an adjacent platen is simple.
As the distillation requires an air purge a mounted air regulator
and precision flow meter are offered as standard equipment. The
distillation water jacket is connected to a low flow water pump
for cooling. Any spillage from the system flows along the deck
gallery to a waste outlet at the rear of the unit.
An acrylic safety cover is supplied with each assembly. The
distillation head can easily be removed from the mounting stem
by slackening a single plastic knob on the universal clamp. The
heating bath is accessed by lifting the manifold platen.
On-site installation and training in the use of the system are
available. For details on flow injection systems, continuous
flow analysers, data handling systems and specialised process
control equipment please contact Burkard Scientific.
