General instructions
Read the operating instructions completely
before starting up and follow the safety inst-
ructions.
•
Keep the operating instructions in a place where they
can be accessed by everyone.
•
Ensure that only trained staff work with the device.
•
Implement the accident prevention regulations for
this typ of activity and workplace. Wear your personal
protective equipment at all times when working with
the laboratory reactor.
•
Only use the device under an all side-closed exhaust,
or a comparable protective device.
•
Do not use flammable or explosive gases, vapours or
solvents in the laboratory reactor!
•
Any reaction vapour released at the reactor lid must
be extracted.
•
The device is not designed for use in explosion hazard
(Ex-certificate) areas!
•
Certain applications and materials may be hazardous.
You should take precautions to prevent contact with,
or inhalation of, toxic liquids, gases, fumes, vapours
or powders.
•
Risks may also be posed by biological or microbiologi-
cal substances.
Do not touch rotating parts.
DANGER
Moving and rotating equip-
ment parts also constitute a
hazard.
There is a danger of crushing
CAUTION
when lowering the reactor lid.
Power supply / switching off the device
The safety disconnector does
CAUTION
not apply to the heating bath.
•
Devices that need to continue operation once the
reactor cover has been opened (e.g. thermostat), must
not be operated via the safety disconnector.
•
Only operate the device under a laboratory extractor
hood (closed on all sides) or other appropriate safety
device.
•
There must be an EMERGENCY STOP facility which
disconnects all poles to the laboratory reactor system
from the power supply. The laboratory reactor must
only be operated using the safety disconnector pro-
vided or in an extractor hood with emergency stop.
•
Connect the laboratory stirrer and the disperser drive
to the mains power supply over the LR-2.SI safety dis-
connector. Connect these devices to the multisocket
on the safety disconnector only
•
Connect these devices to the locked socket strip with
safety disconnector only.
Safety instructions
Performing trials
DANGER
•
The laboratory stirrer/disperser is fitted with a limit
switch which prevents the unit from being started until
it is in the fully lowered position. The anchor stirrer and
the dispersing element must only be operated when
the reactor vessel is fully closed.
•
Do not start up the laboratory reactor when it is open.
Device configuration
DANGER
WARNING
•
The reactor system must always be ventilated when
working under normal pressure in order to prevent any
pressure build-up caused by highly volatile gases or
unpredictable reaction pressure gradients. Condense
volatile gases using a cooler with a standard ground
connector (e.g. a reflux condenser) on the reactor
cover.
•
The device is designed for operation at vacuum settings
up to 25 mbar (see Accessories).
•
Please follow the safe procedures specified for hand-
ling reactants and reaction products.
•
The laboratory reactor vessels may only be heated
without pressure using the double shell with ther-
mostats or similar heat sources. Do not under any
circumstances use a heating mantle or a hot plate
(Bursting hazard!).
•
We recommend that you use the IKA HBR 4 digital
heating bath to temper the LR 2.1 single-walled labo-
ratory reactor vessel.
Heating
CAUTION
•
Ensure that the thermostat used for tempering is fully
efficient. A defective thermostat can cause uncontrol-
led reactions.
Chilblains/burns due to low/
high temperatures on the hose
coupling. Open the hose cou-
pling only at room tempera-
ture.
Glass breakage due to pressure
differences at the quick-release
connectors.
When
quick-release connectors the
double jacket is completely
sealed. Pressure differences
can occur due to cooling/war-
ming of the medium.
Tempering liquids must be at
room temperature when chan-
ging/releasing. The equipment
is not designed for overpressu-
re use.
Burns Hazard. The heated reac-
tor vessel and cover are very
hot. Wear protective gloves
when handling hot parts.
