Introduction:

Your Fisher Isotemp stirrer, hotplate, or stirring hotplate is a general purpose
heating and/or stirring device intended for general indoor laboratory procedures.
The unit is available as a stirrer , hotplate, or stirring hotplate. (Although the unit
is available in three different configurations, the operation of the heat and stir
controls remains the same.
Heat and stir speed are accurately controlled to maintain the set temperature and
stirring speed. Heat and stir speed are easily set by simple controls on the front
panel. Temperature can be precisely set in 1 degree increments between 30°C
(86°F) and 550°C (1022°F). Temperature can be displayed in degrees Centigrade
or Fahrenheit. Both set and actual temperature are displayed. During operation
and after the heat is turned off, the hot top indicator lights if the top is too hot to
touch (>40°C/104°F).
An optional immersion probe allows direct, precise control of the temperature
from inside the solution. This chemical-resistant probe can be used to monitor
actual solution temperature when stirring temperature-sensitive samples. A
standard support rod can be attached to the unit for mounting the temperature
probe, as well as a thermometer, electrode, or buret.
Stirrer speed can be set in 1 RPM increments between 60 and 1200 RPM
(revolutions per minute). The unit automatically adjusts motor strength to
accommodate aqueous, viscous, or semi-solid solutions. Set and actual stir speed
are displayed. Included with stirring units is a 5/16-inch diameter by 2 inch long
(0.8 x 5.1 cm) Teflon-coated stir bar.
The unit ceramic top plate that measures 7x7 inches. The ceramic top stays flat
even at maximum temperature for uniform heating. The ceramic top also resists
acids and alkalis, and is easy to clean. Its reflective white surface allows easy
visualization of contrasts within the sample. The unit's rugged cast-aluminum
base enhances its stability on the bench top. The overall low-profile design
makes the unit easy to use in a hood.
Note: Use vessels with flat bottoms for the best heat transfer. Avoid metal
containers, sandbaths, or vessels with a rim around the bottom as these could
damage the ceramic top plate.

This product contains refractory fiber, insulation which can produce respirable
fibers and dust when unit is disassembled. These fibers or dusts can cause
irritation and can aggravate pre-existing respiratory disease. The insulating
materials are located in the top plate assembly. There may be a risk of exposure
to respirable dusts or fibers when repairing or maintaining the insulating
materials in a manner which causes the release of dust or fibers. Refer servicing
to qualified personnel.
Qualified personnel should consult the appropriate Material Safety Data Sheets
(MSDS's) for such products with respect to proper handling and appropriate
protective equipment..
Note: This unit contains materials which may emit a slight odor or smoke during
initial operation. This will dissipate within an hour and will not affect the
Operation or performance of the hotplate.
Indicates that the surfaces may be hot.
Indicates a shock hazard from dangerous voltage.

Safety Information:

To Avoid Electrical Shock, always:
Use a properly grounded electrical outlet of correct voltage and current
handling capacity.
Disconnect from the power supply prior to maintenance and servicing.
To Avoid Personal Injury:
Do not use in the presence of flammable or combustible materials; fire or
explosion may result. This device contains components which may ignite
such materials.
Space unit at least 6 inches away from any combustible materials under all
conditions.
Use caution when heating volatile materials; top surface and element can
reach the flash point temperature of many chemicals. These hot plates and
stirring hot plates are not explosion proof. Fire or explosion may result.
Unit contains components which may ignite such materials.
Keep top surface clean. Use a non-abrasive cleaner. Alkali spills,
hydrofluoric acid spills or phosphoric acid spills may damage top and lead
to thermal failure. Unplug unit and remove spills promptly. Do not
immerse unit for cleaning.
Replace the top immediately if damaged by etching, scratching or chipping.
A damaged top can break in use.
DO NOT USE METAL FOILS OR CONTAINERS, INSULATING
MATERIALS (e.g. sand baths), or LOW MELTING POINT GLASS (e.g.
soda lime glass) CONTAINERS on hotplate. Ceramic plate can be
damaged creating shock hazard.
Do not remove or modify grounded power plug. Use only properly
grounded outlets to avoid shock hazard. Not rated for use in hazardous
atmospheres.
Use appropriate hand and eye protection when handling hot containers
and/or hazardous chemicals.
Unit should set on a dry surface. Do not set in a puddle of liquid.
