The IKA
®
C 3000 isoperibol calorimeter system is used for calorific
value determination of solid and liquid substances.
This is done by placing a known quantity of a substance in a de-
composition vessel which is surrounded by a water jacket. The
sample is then combusted in an oxygen atmosphere . The calorific
value of the sample can then be calculated from the resulting in-
crease in temperature, the sample mass and the known thermal
capacity of the overall system.
The IKA
®
C 3000 isoperibol calorimeter system is subject to the
Pressure Vessel Directive 2014/68/EU comply with the safety in-
structions accordingly.
For adaptation to individual laboratory tasks, use original
IKA
®
consumables and accessories.
Correct use
The section “Description of system components“ describes the
system components, and the section “The standard calorimetric
procedure“ describes the essentials of calorimetry.
The calorimeter system is ready to perform measurements once
you have completed the procedures in the section “Setting up and
commissioning“, “Preparing a measurement“ and “Starting a mea-
surement“.
In this chapter you can find out how to work through these Oper-
ating Instructions most effectively to be able to work reliably with
the calorimeter system.
The instructions in the section ”Safety instructions“ must
be complied with.
The chapters are designed for you to work through them in order.
The section “Transport, storage“ is relevant for system reliability
and for ensuring high measuring accuracy.
User instructions
upto 27 °C; water consumption per measurement about
• 4 l; water pressure max. 1 bar upto 1.5 bar.
• Operation with active cooling unit 17-27 °C (e.g.
IKA
®
RC2;
optional)
• Measurement and calculation of gross calorific value according
to ISO 1928, ASTM D4809, ASTM D5865, ASTM 240, GB T213
• Calculation of net calorific value according to ASTM D4809,
ASTM D5865, ASTM 240, GB T213.
• Measurement range: max. 40,000 J (This corresponds to an
increase in temperature in the decomposition vessel of approx.
5 K).
System properties
The calorimeter system IKA
®
C 3000 isoperibol is routinely used
for deter-mination of gross calorific values of solid and liquid sub-
stances. The accessories of the system ensure customized adapta-
tion to laboratory tasks.
The system is characterized by the following features:
• Relieves you of routine tasks through automated measurement
procedure
• Integral oxygen filling
• Operation without the cooling unit: Connection to a water fau-
cet with the pressure valve IKA
®
C 25; temperature range 12 °C
DANGER
If the maintenance, and especially
the pressure testing, is not perfor-
med or is performed incorrectly,
there is a risk the decomposition vessel may burst or an
uncontrolled internal fire may occur at the electrodes
which could burn away the seals (oxyacetylene torch ef-
fect), thus posing a risk to life and limb.
• Only technical experts may perform pressure tests and ser-
vice work on the decomposition vessel.
• We recommend that you send the decomposition
vessel to our factory for inspection, and if necessary,
repair after 1000 tests or after one year or sooner
depending on use
•
• A pressure test must be performed after a decomposition
vessel has reached or exceeded the recommended number
of ignition cycles. Once the pressure test has been performed
a release code can be entered to enable the decomposition
vessel to be used for further measurements (see the sections
“Maintenance of the Decomposition Vessel” and “Inputting
a Service Code”).
The warning message will then disappear!
Note: You can then continue to use the device / decomposi-
tion vessel.
• Contact the IKA
®
Service Department to perform the pressure
test. Comply with the safety instructions in this respect. The
user will be given specific instructions on the relevant screen.
For the purposes of these operating instructions a technical
expert is someone:
1. who guarantees to conduct the tests properly on the
basis of his training, knowledge and experience gained
through practical work,
2. who is sufficiently reliable,
3. who is not subject to any instructions in terms of the
test activity,
4. who has suitable test equipment if necessary,
5. who can provide appropriate proof of the requirements
listed in 1.
NOTICE
National directives and laws must
be observed for operating pressure
vessels!
• Anyone operating a pressure vessel must keep it in a proper
condition, operate it properly, supervise it, carry out the ne-
cessary maintenance and repair work immediately and im-
plement the safety measures required in the circumstances.
