Proper Use - IKA LR-2.ST Operating Instructions Manual

The equipment is not designed for overpressure use.
The appliance is designed for operation at vacuum settings up to 25 mbar (see Accessories).
Please follow the safe procedures specified for handling reactants and reaction products.
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 microbiological substances.
Moving and rotating equipment parts also constitute a hazard.
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.
If the anchor stirrer or dispersing element rotate when they are covered in a product and the reactor is open,
this will cause parts or liquids to be projected outwards.
The LR 2000.1 and LR 2000.2 laboratory reactor vessels may only be heated without pressure using the dou-
ble shell with thermostats 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 labora-
tory reactor vessel.
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 maximum permitted temperature inside the reactor vessel is 230°C. Do not exceed this temperature.
Burns Hazard. The heated reactor vessel and cover are very hot. Wear protective gloves when handling hot
parts.
Use the splinter guard provided. It will also prevent you from accidentally touching the hot reactor ves-
sel.
Ensure that the thermostat used for tempering is fully efficient. A defective thermostat can cause
uncontrolled reactions.
Before you fill the reactor vessel, ensure that the reagents used do not corrode the FFPM seal.
Only use IKA

te and optimise chemical reaction processes and can also be used for mixing, dispersion and
homogenisation in modelling processes.
The working volume is 500 to 2000 ml.
Thanks to the highly resistant FFPM seals the medium in the reactor vessel can be heated to 230°C. Vacuum ope-
ration is possible up to 25 mbar (see Accessories).
By adapting the VM 600 Basic Visco Module (see Accessories) you will also be able to use torque measurements to test
the rheological properties and the flow and deformation behaviour of materials.
The IKA ® laboratory equipment range is vast. It provides numerous opportunities for building equipment combinations
customised for a wide variety of individual applications.
You can use these in conjunction with labworldsoft
suring, controlling, regulating and fully documenting all laboratory processes.
