• The equipment is designed for operation at vacuum set-
tings up to 25 mbar.
• 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.
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 connec-
tor (e.g. a reux condenser) on the reactor cover.
• Observe the maximum permissible temperatures (see sec-
tion “Technical data“) in the reactor vessel.
Before you fill the reactor vessel,
ensure that the reagents used do
not corrode the seal.
• Ensure that the external temperature sensor is inserted in
the media to a depth of at least 20 mm.
• Only use IKA® approved accessories!
• Use only original IKA® spare parts!
•
When the reactor vessel or the vessel cover is removed
during operation, the stirring and the heating function
will be switched off automatically. Restart the stirring and

Safety instructions
General instructions:
•
Read the operating instructions fully before starting
up and follow the safety instructions.
• Keep the operating instructions in a place where they can
be accessed by everyone.
• Ensure that only trained staff work with the equipment.
• Follow the safety instructions, guidelines, occupational
health and safety and accident prevention regulations.
• Uncontrolled reactions can be triggered by mixing the
heated material insuciently or by the energy generated
by selecting a speed that is too high. In case of these and
other increased operational hazards, users must take additional appropriate safety precautions. In any case, when
using critical or hazardous materials in your processes,
IKA® recommends to use additional appropriate mea-
sures to ensure safety in the experiment. For example, users can implement measures that inhibit fire or explosions
or comprehensive monitoring equipment. Furthermore,
users must make sure that the unit switch of the IKA®
product can be accessed immediately, directly and without risk at any time.
If installation or positioning cannot ensure this access at all times,
an additional EMERGENCY STOP
switch that can be easily accessed must be installed in
the work area.
• Only process media that will not react dangerously to the
extra energy produced through processing. This also applies to any extra energy produced in other ways, e.g.
through light irradiation.
• Do not operate the instrument in explosive atmospheres,
with hazardous substances or under water.
• Process pathogenic materials only under a suitable fume
hood. Please contact IKA® application support if you
have any question.
• Set up the device in a spacious area on an even, stable,
clean, non-slip, dry and fireproof surface.
• Protect the instrument and accessories from bumping and
impacting.
•

from the power supply.
Covering or parts that are capable of
being removed from the unit with-
out accessory equipment have to be
reattached to the unit for safe operation in order to prevent, for example, the ingress of fluids, foreign matter, etc..
Stirring and dispersing:
• Moving and rotating equipment parts also constitute a
hazard.
Rotating tools are dangerous! The
anchor stirrer and the dispersing el-
ement must only be operated when
the reactor vessel is fully closed. Do not start up the laboratory reactor when it is open.
• If the 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.
• Gradually increase the speed.
• The equipment may heat up by stirring.
Heating:
Risk of burns! Exercise caution when
touching the heating block and the
glass vessel. The cover of the vessel could reach high temperature when you boil liquid for
long time. Pay attention to the residual heat after switching off.
Only process and heat up any me-
dia that has a flash point higher
than the adjusted safe temperature
limit that has been set (see section “Technical data“).
The safe temperature limit must always be set to at least
25 °C lower than the fire point of the media used.
• Use:

Menu (Details):
Stirring:
Torque trend measurement:
The torque trend measurement is used to deduce the
change in viscosity of the reaction medium. The device is
not designed to measure absolute viscosity. It only measure
and display the relative change in the viscosity of the medium from a starting point specified by the user.
The value can always be reset to 0% by pressing the “Back”
(T, see Fig. 12) membrane key.
Note: Torque trend measurement only works for a constant set speed for the duration of the measurement.
As a result, intermittent mode cannot be used in conjunction
with torque trend measurement.
The current control variable is saved as the reference 0%,
ΔP and shown on the digital display. The change in the viscosity is then shown in %. Depending on whether the viscosity increases or decreases, the percentage rises or falls
above or below 0% respectively.
Intermittent mode:
The menu allows the user to activate the “Run/Stop“ function. The run time and stop time can be set separately.
Speed limit:
The menu allows the user to set the desired maximum upper speed limit for the reactor system. The initial setting is
the maximum permissible speed of the stirrer. If the user
changes this setting, control system of the reactor saves the
new value for future stirring tasks.
If the “Speed Limit” has been changed, then the speed can
be adjusted only within the new range.
Heating:
Control mode:
In the menu, the user is allowed to select “Accurate” or
“Fast” control mode by rotating and pressing knob (A). The
selected control mode is indicated by a tick.
Fast: reach target temperature quickly but with big overshoot and large hysteresis
at the beginning.
Accurate: Reach the target temperature takes somewhat
longer, but for this reason,
the initial overshoot and
the hysteresis are significantly smaller.
Limits:
In “External (ext)“ option, the user is allowed to set the maximum and minimum temperature for external temperature
control. Confirm and store the setting by pressing on “OK“.
Temperature sensor:
In “Calibration“ option, the user is allowed to calibrate the
external temperature sensor.
Weighing:
Measurement:
With the weighing function, the user can perform simple
weighing tasks.
Note: The heating and stirring functions must be deactivated.
Calibration:
• Open the “Calibration” submenu and confirm by press-
ing the rotary knob (A, see Fig. 12)
• Enter the calibration weight and conrm by pressing the
rotary knob (A, see Fig. 12).
• Place the calibration weight on the device and wait until
the device indicates that the calibration process has been
completed.
Depending on the selected calibration mode, 2-point or
3-point must follow these steps two or three times.
Once the calibration process has been completed successfully, the weighing module is ready for use.

The device can be operated in “Remote” mode via the RS 232
interface or the USB interface connected to a PC and with the
laboratory software Labworldsoft®.
Note: Please comply with the system requirements together with the operating instructions and help section included
with the software.
USB interface
The Universal Serial Bus (USB) is a serial bus for connecting
the device to the PC. Equipped with USB devices can be con-
nected to a PC during operation (hot plugging). Connected
devices and their properties are automatically recognized.
Use the USB interface in conjunction with
Labworldsoft® for
operation in “Remote” mode and also to update the firmware.
USB device drivers
First, download the latest driver for IKA
®
devices with
USB interface from http://www.ika.com/ika/lws/down-
load/usb-driver.zip and install the driver by running the
setup file. Then connect the IKA® device through the USB
data cable to the PC.
The data communication is via a virtual COM port. Configuration, command syntax and commands of the virtual
COM ports are as described in RS 232 interface.
RS 232 interface
Configuration
- The functions of the interface connections between the
machine and the automation system are chosen from the
signals specified in EIA standard RS 232 in accordance
with DIN 66 020 Part 1.
- For the electrical characteristics of the interface and the
allocation of signal status, standard RS 232 applies in accordance with DIN 66 259 Part 1.
- Transmission procedure: asynchronous character transmis-
sion in start-stop mode.
- Type of transmission: full duplex.
- Character format: character representation in accordance
Interfaces and output
with data format in DIN 66 022 for start-stop mode. 1
start bit; 7 character bits; 1 parity bit (even); 1 stop bit.
- Transmission speed: 9600 bit/s.
- Data flow control: none
- Access procedure: data transfer from the stirrer machine to
the computer takes place only at the computer’s request.
Command syntax and format
The following applies to the command set:
- Commands are generally sent from the computer (Master)
to the stirrer machine (Slave).
- The stirrer machine sends only at the computer’s request.
Even fault indications cannot be sent spontaneously from
the stirrer machine to the computer (automation system).
- Commands are transmitted in capital letters.
- Commands and parameters including successive param-
eters are separated by at least one space (Code: hex 0x20).
- Each individual command (incl. parameters and data) and
each response are terminated with Blank CR LF (Code: hex
0x20 hex 0x0d hex 0x20 hex 0x0A) and have a maximum
length of 80 characters.
- The decimal separator in a number is a dot (Code: hex 0x2E).
The above details correspond as far as possible to the recommendations of the NAMUR working party (NAMUR recommendations for the design of electrical plug connections
for analogue and digital signal transmission on individual
items of laboratory control equipment, rev. 1.1).
The NAMUR commands and the additional specific IKA® commands serve only as low level commands for communication
between the machine and the PC. With a suitable terminal or
communications programme these commands can be transmitted directly to the equipment. The IKA® software package, labworldsoft®, provides a convenient tool for controlling
device and collecting data under MS Windows, and includes
graphical entry features, for motor speed ramps for example.
The following table summarises the (NAMUR) commands
understood by the IKA® control equipment.

“Watchdog” function, monitoring the serial data flow
The following applies to situations where the watchdog function is enabled (see Namur instructions). If no new transmissions of these commands from the PC take place within the preset watchdog time, the heating and shaking functions will
be shutdown according to the watchdog mode selected or will be controlled using the preset setpoints. An operating
system crash, a PC power failure or a fault in the connecting cable to the instrument can cause an interruption in data
transmission.
“Watchdog”– Mode 1
If an interruption in data transmission occurs which is longer than the preset watchdog time, the heating and shaking functions will be shut down and the error message PC 1 will be displayed.
