Section 1
Section title
Ignoring the following cautions could cause injuries or property damages..
Do not touch the top plate or any object near it even when the heater is
turned off. You may get burned due to residual heat.
After using this equipment, make sure to turn off the main power switch
and also to disconnect the power cord from the power outlet for the
safety of other users.
Do not place heavy objects, including this equipment, on top of the
power cord and do not strip, scratch, bend, twist, pull, or heat the
power cord. A damaged power cord is a fire and electrical shock hazard.
Do not allow moisture or water to get into the instrument. Fire or electri-
cal shock may result.
Beware of the effects of the magnetic field generated by this instrument.
Magnetic field can affect certain devices such as cardiac pacemaker, data
storage media, and so on.
Make sure to set up your instrument on a flat, stable, clean, non-slip, dry,
and fireproof surface inside a lab with proper safety measures.
Do not place any device which can be affected by the motor vibrations
near this equipment.
Do not touch the power outlet, power socket, or power cord with wet
hands. And make sure to connect the power cord directly and firmly to
the power outlet and power socket.
Do not put or insert any objects (especially if conductive or flammable)
inside this equipment.
Beware that mechanical shock or vibration can damage this equipment
and pay extra attention while moving it. Damages caused by mechanical
shock or vibration may result in injury or fire.
Do not impact the heat sink. You can damage the equipment or get
injured.
Do not install this equipment near any device that generates high fre-
quency noise such as high frequency welding machines, high frequency
sewing machines, or SCR power controllers.
Before cleaning, make sure to unplug the power cord to avoid electric
shock or fire.
Do not use chlorine bleach, ammonia-based cleaners, abrasives, ammonia,
or metal scouring pads. Wipe with a soft damped cloth or a sponge
soaked in water or diluted neutral detergent.

2-2 Hotplate Stirrer Thermo Scientific
Section 2
General Description
Performance Features
• Virtually No Decoupling of Stir Bars - By adopting a special magnet
with exceptionally strong magnetic coupling power as well as smooth-
start stirring mechanism, you will experience virtually no decoupling of
magnetic stir bars even with viscous media or at high speeds.
• Quick Heat Up Time - High heat transfer rate of the tightly integrated
structure of heater and ceramic-coated aluminum alloy top plate allows
quick heat up (up to 350°C).
• Fast and precise stirring speed - Fast and precise stirring speed (up to
2,000 rpm) even at high temperatures is made possible thanks to the
combination of a powerful and precise brushless DC (BLDC) motor
and a special magnet with extremely strong magnetic coupling power.
• Big Stirring Capacity - The BLDC motor and the special magnet also
provide big stirring capacity (up to 20 liter in case of water).
• Constant Stirring Speed - The feedback control design of this
instrument allows you to have constant stirring speed even when the
viscosity of the media changes during operation.
• Instant Halt of the Stirring Operation - Due to the exceptionally fast
response characteristics of the BLDC motor, the stirring operation
stops instantly when the stirrer is turned off.
Safety Features
• High Temperature Safety Limit of the Heating Plate - The default
setting of the temperature limit of the heating plate is 350°C to protect
you and your media.
• Multiple Overheat Prevention Measures - Built-in overheat prevention
circuit will turn off the heater if the top plate temperature reaches
450°C for any reason. In addition, if the temperature of the main body
exceeds 85°C, the overheat prevention circuit stops heating to protect
the motor and the PCB.
• Hot Top Warning Indicator - The top plate temperature can remain
very hot for some time even after the heater is turned off. To prevent
injury or fire under such circumstances, this instrument has a hot top
warning indicator on the control panel. This indicator will illuminate if
the top plate temperature is over 50°C. Even so, do not rely on this
indicator alone for your safety.
Features

Safety Features (continued)
• Heating Bath (Patent Pending) (optional) - A specially designed non-
slip heating bath shown below is available as an option. To prevent
unintentional slips of the bath during operation, this bath has concavo-
convex bottom shown below so that it fits snugly on top of the top
plate.
• Transparent Shield (optional) - A transparent shield is also available to
allow you to monitor your operations more safely by shielding you
against decoupled stir bars or liquid splashes.
• Two large digital displays show top plate temperature, heating level,
stirring speed as well as the set time and the remaining time for the
timer operation.
• When setting the timer, stirring time and heating time can be set
independently or even together, if needed.
• With two separate knobs for heat and speed control, you can set
heating level and/or stirring speed fast and with ease.
• You can easily set your own temperature limit at any value between 50
and 350°C.
• Up to two support rods (optional) can be attached to hold various
kinds of devices such as temperature sensors, thermometers, laboratory
glassware, and so on.
