before operating instrument.
NOTICE:
1. Safety: Different kinds of acid like hydrochloride, nitric acid,
hydrofluoric will be used for sample preparation. Most of acid
are volatile and harmful to health, so operating instrument in
ventilated environment is recommend, various corresponding
protective measures must be taken. When use digestion reagent
contained HClO4, quantity of HClO4 and digestion temperature
must be controlled carefully, then operation security could be
guaranteed, otherwise fire and explosion hazards could be
created
2. Operation: Operating instrument in the environment which is
specified in this manual. When the instrument is not in use,
unplug the plug. When clean the dirt on the surface of graphite
block, wiping with soft cloth, don’t use organic solvent as
possible and don’t destroy the coat on the surface.
3. Storage: The instrument is not in use for a long time，store in
the environment which is specified in this manual.

3. 2 Feature
l Heating module is made of graphite block, temperature control
accuracy is ±0.2℃ .
l Good temperature uniformity, temperature difference of hole is
±1.5℃, ensure good digestion consistency.
l Teflon (PTFE) coat prevent graphite block from eroding by
strong corrosive substance and ensure its long service life.
The anticorrosion design of whole structure ensure it can adapt
to all kinds of wicked environment.
l Corrosion resistance reduce sample contamination.
l Digestion time can be adjusted, depending on sample type and
digestion method.

be set in each heating step. For the sample difficult to digest,
heating step is set flexibly and made to a method database,
maintained conveniently.
l Temperature control range is between room temperature to 210
℃, built in overheating protector. Internal temperature
measurement mode or external temperature measurement
mode can be selected, temperature control accuracy is well.

l Instrument Indicator: “Power”lamp is power supply indicator,
“Hot”lamp is heating indicator “1、2、3”lamp is running
step indicator. Three lamps will light at the same time when the
running step numbers is more than three.
l For treat a great deal samples conveniently
. After place
digestion tube in racket (optional), put them into digestion hole
all together. The sample should be put in the middle digestion
hole as possible is recommend. When there are many samples,
place averagely for the best results. .
