Heating Operation Principles

The heating element and a temperature sensor are located just beneath

the ceramic top surface of the product. The microprocessor controlled

heat, generated by the heating element, is based upon the sensor temperature and the value set on the Heating Temperature Display. When

the sensor temperature is not within range of the value set on the display, the display will FLASH. When the sensor temperature is within

range, the value displayed will remain constantly ON.

The Heating Temperature Display does not indicate the actual temperature of materials placed on top of the product or the actual temperature

of the ceramic top surface.
8 9

The table below shows a typical difference between the temperature set

on the Heating Temperature Display and the actual temperature measurement of the ceramic top surface:

Temperature Set Top Surface Temperature Set Top Surface

on Display (°C) Temperature (°C) on Display (°C) Temperature (°C)

250 205 550 440

(The information above was taken using a 6795-420D with no top load

in 20°C ambient conditions)

Using the External Temperature Controller, Corning Inc. Cat. No.6795PR

enables precision temperature control of materials placed in vessels on top of 

the product.

An External Temperature Controller is available for this product as an

accessory item. See page 11 for more details.

When the External Temperature Controller is connected to the product,

the closed loop control process described previously is extended to

include temperature input from the External Temperature Controller.

The microprocessor controlled heat, generated by the heating element,

is based upon the sensor temperature located in the tip of the External

Temperature Controller and the value set on the Heating Temperature

Display. When the sensor temperature is not within range of the value

set on the display, the display will FLASH. When the sensor temperature

is within range, the value displayed will remain constantly ON.

When the External Temperature Controller is connected to the product

and properly placed into a liquid on the top surface, then the Heating

Temperature Display does indicate and directly control the actual temperature of the liquid on the top surface.

Caution: The top surface and the vessel used may be at substantially

higher temperatures than indicated by the setting on the Heating Temperature Display as the controller regulates the liquid temperature inside

the vessel.

Heating Operation Safety

The microprocessor controlled system has error routines built in to

detect product operation in some unfavorable conditions. The type of

error routines which may be active in a product varies depending upon

the functionality of the model and the operating software version.

If an error routine is engaged, the product will typically shut down.

Some error routines will display an error code number in the left digital

location of the Heating Temperature Display when the product is shut

down. For more information on error codes, call Corning Technical

Service at 978.442.2200.

A product shut down by an error routine must be disconnected and

reconnected to mains input before it can be used again. Please contact

Corning Inc. or a Corning Authorized Repair Facility if a product does

not reset from the error routine shut down or if it continues to shut

down after resetting.

Caution: Error routines built into these products do not substitute the

need to use these products per the specified operating conditions and

according to safe laboratory practices. There are potential failure modes

in product functionality or in process of use that could result in uncontrolled or unexpected heating of the top surface. Reaction plans should

be developed and safety precautions put in place based on the worse case

scenario that any materials placed on the top surface could be subjected

to a continuous supply of heat, raising the material temperature to levels

in excess of 550°C.

Product Repair

There are no direct user serviceable components inside this series of

products. A list of available replacement parts are listed on page 12.

Please contact Corning or a Corning authorized repair facility for 

repair or maintenance issues.

Frequently Asked Questions

◗ I have a beaker of water on my hot plate and set the temperature

for 550°C. Why does the display setting blink and not remain

constant?

The display will blink at any time when the temperature sensor is not

within range of the set temperature value. The temperature measured

by the sensor is a composite of the temperature of the heating element

located beneath the sensor, the ceramic top above the sensor, and the

very small air space around the sensor. Water requires a substantial

amount of heat in order to boil yet remains at a constant temperature

of 100°C for the duration of the boiling process. Although the heating

element is producing maximum heat at the 550°C setting, the water

consumes this heat so quickly during the boiling process that the heat

is unable to raise the temperature measured by the sensor to within

range of the 550°C set value.

◗ How long does it take to bring a beaker of water to boil?

Using a 600 mL PYREX® beaker with 400 mL of water at 25°C, it

takes approximately 15 minutes to bring the water to a full, rolling

boil.

◗ Can I use a metal tray on top of my Corning® hot plate?

No. The metal will act as a heat sink, and have a high probability of

creating an abnormal heating condition. If an abnormal condition is

detected, the product will shut down. A metal vessel will also scratch

the ceramic top plate.

◗ The stir bar keeps decoupling. Why and what can I do to stop this?

These units are programmed to minimize decoupling. However, liquid

viscosity, stir bar magnetic strength, vessel used, and speed changes can

cause decoupling. High viscosity liquids must be stirred at slower speed

settings. The magnetic strength of stir bars can weaken over time and

may need to be replaced. Vessels used need to have thin, flat bottoms

to insure optimal performance. Rapid decreases in stir speed can cause

decoupling as the magnet slows down quicker than the stir bar and the

liquid. 

◗ What size vessel should I use?

Vessels used on the top of a hot plate must not be larger than the 

top plate.

◗ Corning sells replacement parts. Can I do the repairs myself

instead of sending it in to Corning’s equipment repair department?

When repairs are completed by Corning or a Corning authorized repair

facility, the performance and safety of the product will be verified before

being returned to you. We do sell replacement parts so customers can

complete repairs themselves. It is recommended that only people knowledgeable in electronics complete those repairs. There is no warranty

or return on equipment replacement parts.
