The IKA
®
C 6000 global standards/isoperibol cal-
orimeter system is used for calorific value determi-
nation of solid and liquid substances.
This is done by placing a known quantity of a
substance in a decomposition vessel which is sur-
rounded by a water jacket. The sample is then
combusted in an oxygen atmosphere . The calo-
rific value of the sample can then be calculated
from the resulting increase in temperature, the
sample mass and the known thermal capacity of
the overall system.
The IKA
®
C 6000 global standards/isoperibol cal-
orimeter 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 calorimeter system is ready to perform mea-
surements once you have completed the proce-
dures in the section „Setting up and commission-
ing“, „Preparing a measurement“ and „Starting a
measurement“.
Numbers 1, 2, 3 etc. indicate operating instruc-
tions in the following sections. These must always
be carried out in the specified sequence.
In this chapter you can find out how to work
through these Operating Instructions most effec-
tively to be able to work reliably with the calorim-
eter system.
The instructions in the section „Safety in-
structions“ 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. The section „Description of system com-
ponents“ describes the system components, and
the section „The standard calorimetric procedure“
describes the essentials of calorimetry.
User instructions
• Operation with active cooling unit 17-27 °C
(e.g. IKA
®
KV 600; optional)

value according to DIN 51900, ISO 1928, ASTM
D240, ASTM D4809, ASTM D5865, ASTM
D1989, ASTM D5468, ASTM E711
• Calculation of net calorific value according to
DIN 51900, ASTM D240, ASTM D4809, ASTM
D5865, ASTM D1989, ASTM D5468, ASTM
E711
• Measurement range: max. 40,000 J (This cor-
responds to an increase in temperature in the
decomposition vessel of approx. 5 K).

System properties
The calorimeter system IKA
®
C 6000 global stan-
dards/isoperibol is routinely used for deter-mina-
tion of gross calorific values of solid and liquid
substances. The accessories of the system ensure
customized adaptation to laboratory tasks.
The system is characterized by the following fea-
tures:
• Relieves you of routine tasks through automated
measurement procedure
• Integral oxygen filling/degassing
• Automatic detection of decomposition vessel
• Operation without the cooling unit: Connection
to a water faucet with the pressure valve IKA
®
C 25; temperature range 12 °C upto 27 °C; wa-
ter consumption per measurement about 4 l;
water pressure max. 1 bar upto 1.5 bar.
