2.0 Product Description
Corning® Hot Plates and Stirrers have been a laboratory standard for over 50 years. Our
products have been engineered with customer input to be reliable, precise, safe, and easy to
use. This product features:
◗ A microprocessor that provides linear control for both heating and stirring to ensure
consistent performance.
◗ Enclosed control electronics that protect sensitive components from harsh environments
and reduce maintenance time and costs.
◗ The Pyroceram® top plate is easy to clean and highly resistant to scratches, corrosion, and
chemical attack. It is also flatter to provide faster, more uniform heating, and is whiter to
provide better contrast during applications which require monitoring of color changes.
◗ Rigorous testing standards for electrical safety, EMI (Electro Magnetic Interference),
and regulatory approvals. Corning Hot Plates and Stirrers meet UL (USA), CSA (Canada),
IEC61010 CE (Europe), GS (Germany), FCC regulations and others where appropriate.
◗ International symbols for power, heat, stir, and hot top.

3.0 Operating Conditions
Corning® PC-200 series Hot Plates and Stirrers are designed to be safe under the
following conditions:
◗ Indoor use
◗ Altitude up to 2,000 meters
◗ Temperature of 0°C to 40°C
◗ Maximum relative humidity 80% for temperatures up to 31°C
◗ Main supply voltage fluctuations not to exceed ±10% of the nominal voltage
◗ Installation Category II
◗ Pollution Degree 2
◗ Position at least 30 cm from walls, 1.2 meters from ceilings, and 30 cm between hot plates
if using multiple units.
4.0 Warnings
◗ Always wear safety glasses and other appropriate protection when operating this
equipment.
◗ Keep the Pyroceram® top plate clean. Use non-abrasive cleaner. Spills may damage the
top and lead to thermal failure. Unplug the unit and remove spills promptly. Should the
top plate become damaged by etching, scratching, or chipping, replace the top plate
and element assembly immediately using the manufacturer’s complete assembly and
instructions.
◗ Do not immerse the unit for cleaning.
◗ Do not heat or stir volatile materials.
◗ Do not use foil, fiberglass pads, or other insulating materials on the top of the unit when
heating. Heat settings above 5 are not recommended for sand bath applications.
◗ Do not modify or substitute the earthed power plug. Use only power cords supplied by the
manufacturer. Use only properly earthed outlets to avoid shock hazard.
◗ Do not modify the unit electrically or mechanically as personal injury or product damage
may occur.
◗ Do not use ring stand to support unit on lattice or for support of heavy loads. Gross
weight on top of any unit should not exceed 11 kg.
◗ Not explosion- or spark-proof.
◗ Not for industrial use. These units are designed for use in laboratory environments by
persons knowledgeable in safe laboratory practices.
◗ Do not use equipment in a manner other than stated in the Operating Conditions section
since the protection provided by the equipment may be impaired.
◗ Do not use metal containers or large heavy wall glass containers on top of the unit
when heating.

5.0 Heating Operation and Controls
◗ The microprocessor ensures minimum heat-up times for samples by supplying maximum
power to the heating element until the set point is reached.
◗ Top quality insulation keeps the heat on the top, away from controls and the lab bench,
saving more energy than competitive units.
◗ The Hot Top Indicator light warns that the top plate is too hot to touch (>60°C).
◗ The Temperature sensor provides power cutoff in abnormal situations by limiting top plate
temperature to 550°C.
Heating Operation
Fill the vessel with solution. For stirrers and stirrer/hot plates only, place the provided stir
bar into the vessel, and set the vessel in the center of the top plate. Plug the line cord into
an earthed power outlet – the green power indicator light will illuminate. Turn the heat
knob clockwise to the desired setting. The amber heat light to the left of the heat knob will
illuminate. Hot top indicator light will illuminate and remain on when temperature of the
top plate reaches approximately 60°C.

9 - 10 480°C
NOTE: Temperatures listed above are typical with no top load.
Actual temperatures will be governed by dial setting and top load.
6.0 Stirring Operation and Controls
◗ Exclusive closed-loop stirring control monitors and regulates the stirring speed – sensing
your requirements whether you’re stirring an aqueous, viscous, or semi-solid solution.
◗ Stirring control provides a “cushioned” reaction to large increases in speed to minimize
decoupling.
Stirring Operation
Fill the vessel with solution. For stirrers and stirrer/hot plates only, place the provided stir
bar into the vessel, and set the vessel in the center of the top plate. Plug the line cord into
an earthed power outlet. The green power indicator light will illuminate. Turn the stir
knob clockwise to the desired setting. The amber stir light to the left of the stir knob will
illuminate.

7.0 Inspection Procedure
◗ Look for etching, scratching, or chipping on the top plate. If any of these conditions are
present, replace the complete top plate element assembly immediately.*
◗ Check if the power cord is damaged. If the cord is damaged, replace immediately.*
8.0 Preventative Maintenance
◗ Disconnect power by unplugging the unit before performing any maintenance or service.*
◗ Always use an earthed outlet.
◗ Keep the Pyroceram® top plate clean. Unplug the unit, and use non-abrasive cleaner.
◗ Clean spills promptly. Unplug the unit, and use a non-abrasive cleaner.
◗ Do not immerse the unit for cleaning.
*Service should always be performed by a qualified technician using Corning parts and instructions.
Please contact a Corning authorized repair facility for service and repair.
