Your Barnstead|Thermolyne SUPER-NUOVA hot plate or
stirring hot plate is a heating and/or stirring plate designed
for laboratory procedures requiring precise control of tem-
perature and/or stirring speed. Each SUPER-NUOVA model
includes a digital display for monitoring temperature and/or
stirring speed, and the stirring hot plate models have dual
displays so temperature and stirring speed can be moni-
tored simultaneously. The hot plate is capable of producing
accurately controlled top plate temperatures from 1°C
through 300°C. The temperature is controlled at the plate
surface by an internal Type K thermocouple sensor, or the
solution temperature may be controlled by utilizing the
included 6" PFA encapsulated ungrounded stainless steel
Type K thermocouple probe. A 6" or 10" general purpose
stainless steel immersion probe, or a chemical-resistant 7"
solid Teflon®immersion probe may be ordered separately.
The stirrer will accurately maintain stirring speeds from 50
rpm up to 1200 rpm. On stirring hot plate models, the
accessory probe may also be utilized to display the actual
temperature of heat-sensitive solutions during stirring-only
functions. The top plate on the SUPER-NUOVA units are
solid aluminum, and are suitable for use with glass or metal
vessels and sand baths.
Other features of the SUPER-NUOVA include a timer that
can be used to shut off stirring, heating or both. Specific
temperature or stirring speed setpoints may be set using
the PRESETS buttons on the SUPER-NUOVA. An over
temperature protection (OTP) circuit can be set using the
adjustment on the front face of the unit. The OTP can be
displayed in the service menus. See “Service and
Calibration.”
An RS232 port is available on the SUPER-NUOVA to output
elapsed time, speed, and temperature data. The data is
printed once every second when the unit is powered on
(displays on). See “RS232 Output” in the Operation section
of this manual.
Your SUPER-NUOVA plate may be used for general pur-
pose heating applications and/or general laboratory mixing
of solutions, including sample preparation, heating
reagents, melting paraffin, warming resinous chemicals,
content analysis, solvent evaporations, digestions, media
preparation and sterilization, titrations, sand baths, and
microscale chemistry applications.

Features

Each SUPER-NUOVA unit utilizes the latest microproces-
sor technology to deliver the most reliable, accurately
controlled, aluminum top digital plate on the market.
Your SUPER-NUOVA plate has an electronic, closed-loop
feedback control which will accurately maintain tempera-
ture setpoints from 1°C through 300°C.
The SUPER-NUOVA units use a Type K thermocouple for
measuring the top plate temperature, OTP and the exter-
nal probe. Both top plate surface and OTP temperature
are measured with independent analog circuits. This pro-
vides a significant increase in safety due to the redundan-
cy of the circuits. It is possible to heat certain types of
metal vessels and sandbaths on the SUPER-NUOVA
without damaging the aluminum top.
The electronic stirring speed control will maintain the
speed setpoint when the unit is loaded. The motor is com-
bined with a powerful magnet to provide exceptional mag-
netic coupling with a stir bar.
The timer feature on the SUPER-NUOVA can be pro-
grammed to turn off the stirring, heating or both. The
default setting is to turn off heating only. See “Setting the
Timer” section of this manual. To change default setting,
see “Service and Calibration/Timer Shutdown”.
12
Principles of Operation
Note
This plate does not cool. The mini-
mum temperature is 1°C if used in a
cold room at 1°C.

Power Button
The SUPER-NUOVA unit has a power button located on
the front control panel. The unit may be powered on by
pressing the power button or ANY button on the control
panel. When the unit is turned on, there will be three
beeps, the unit will initialize and then “OFF” will be dis-
played on both the “HEAT” and “STIR” display screens
until a temperature and/or stirring speed are entered. To
turn off power to the unit, press the power button.
Setting the Stirring Speed
The SUPER-NUOVA stirring hot plate has an electronic
feedback speed control which will maintain a precise
speed setpoint from 50 rpm through 1200 rpm. (Maximum
speed is dependent on viscosity of the solution.) The
SUPER-NUOVA stirring hot plates are equipped with a
strong magnet and high torque motor which will draw a
vortex in fluids up to 700 cp.
To set the stirring speed, press “SET” key located under
the STIR display. Use the knob in the center of the con-
sole to select a speed. Turn the knob clockwise to
increase the speed or counterclockwise to decrease the
speed. When desired speed has been reached, press
the “SET” key under the STIR display or wait a moment
and the unit will beep indicating that it has been set. The
SET indicator light will be lit when in SET mode.
Once the unit begins stirring, the display will register
ACTUAL speed until the setpoint has been reached. To
check the setpoint, press “SET” under the STIR display
and your setpoint will be displayed again for a few sec-
onds. The display will automatically return to indicating
actual speed. To stop the stirring action without changing
your setpoint press the PAUSE button once. The PAUSE
indicator will be lit and the word PAUSE will scroll across
the display. To resume stirring at the set speed, press the
PAUSE button again.
To turn stirring off, press “SET” under the STIR display
and turn the knob counterclockwise until the display reads
“OFF.” Alternatively, the stirring can be turned off by
pressing and holding the “SET” STIR key until a beep is
heard (approximately 3 seconds.)
Operation
Warning
Use caution when heating volatile
materials; top surface and element
can reach the “Flash Point
Temperature” of many chemicals.
These plates are not explosion proof.
Fire or explosion may result. Unit con-
tains components which may ignite
such materials.
Use appropriate hand and eye protec-
tion when handling hazardous chemi-
cals.
“Caution: Hot Top. Avoid Contact.” The
top plate of the unit can remain hot for
some time after use. A “CAUTION -
HOT TOP” light will remain on until top
plate temperature cools to below
50°C.
Note
The knob does not function unless
one of the “SET” buttons is pushed
first to activate it.
13

14
Note
The temperature display will indicate
the actual temperature of the top
plate (1°-300°C). This plate does not
cool. The minimum temperature is
1°C if used in a cold room at 1°C.
Note
The top plate temperature will be
higher than the solution temperature.
OPERATION
Setting the Temperature
The SUPER-NUOVA hot plate and stirring hot plate has
an electronic closed-loop feedback control which will
accurately maintain temperature setpoints from 1°C
through 300°C. A “CAUTION HOT TOP” light on the front
panel will illuminate whenever the top surface tempera-
ture exceeds 50°C. The temperature may be controlled
either at the top plate by the internal Type K thermocou-
ple sensor, or in the solution using an accessory
ungrounded Type K thermocouple probe. If a probe is
used, the “External Probe” light will be illuminated on the
front panel. (A 6" or 10" stainless steel general purpose
immersion probe [part numbers TC732X1 and TC732X2],
or a chemical-resistant 7" Teflon immersion probe [part
number TC727X2] are available by contacting Barnstead
International, 800-553-0039). The SUPER-NUOVA plate
will accept any ungrounded Type K thermocouple probe,
however the accuracy of probes other than those tested
and specified may not reach the probe accuracy rating
designated.
To set the temperature, press “SET” key located under
the HEAT display. Use the knob in the center of the con-
sole to select a temperature. Turn the knob clockwise to
increase the temperature or counterclockwise to decrease
the temperature. When desired temperature has been
reached, press the “SET” key under the HEAT display or
wait a moment and the unit will beep indicating that it has
been set. The SET indicator light will be lit when in SET
mode.
Once the unit begins heating, the display will register
ACTUAL temperature until the setpoint has been reached.
To check your setpoint, press “SET” under the HEAT dis-
play and your setpoint will be displayed again for a few
seconds. The display will automatically return to indicating
actual temperature. Keep in mind, drafts and other tem-
perature fluctuations will affect temperature accuracy.
Note
Boiling times are dependent on solu-
tion volume and the surface area of the
flask that is exposed to the hot plate.
For example, when heating the same
amount of solution in a 2L flask vs. a
1L flask, the solution will heat about
20% faster.

15
Controlling Solution Temperature
Using External Probe
To control the solution temperature plug the included probe or
an ungrounded Type K thermocouple probe into the probe
receptacle located on the right side of the unit. Be careful to
observe the correct polarity of the probe connector when
inserting probe. Place the probe into the solution. The display
will indicate the actual temperature of the solution as meas-
ured by the probe, and the probe indicator LED on the front
panel will be illuminated. Keep in mind, drafts and other tem-
perature fluctuations will affect temperature accuracy.
The external probe offers more exact temperature control
than regulating the top plate by the internal sensor. If you
need to maintain a precise setpoint it is recommend to use a
probe to control the solution temperature instead of controlling
by the top plate temperature.
When using a probe with the SUPER-NUOVA plate it is rec-
ommended that a clamp on a support rod be used to hold the
probe in the solution.
To ensure accurate probe readings, as much of the probe
sheath as possible should be immersed in the solution. Make
sure the probe is immersed in the liquid and is not located in
air or outside of the solution in the center of the stirring vortex.
If the probe is plugged into the plate, but is not in solution
while the heat control is operating, the temperature display
will continue to indicate an ambient temperature, and a probe
out of solution error will occur. Because the set point cannot
be reached the element will continue to supply heat to the top
plate, and the maximum top plate temperature of 300°C may
be reached. If the remote probe does not sense a tempera-
ture change in three minutes the unit will display a heating
error and shut down. If more than three minutes is required,
see “Service and Calibration/Probe Response.”
OPERATION
Note
The top plate temperature will not
exceed the 300°C maximum.

16
Using Preset Programs
The SUPER-NUOVA plate features the option of presetting
4 setpoints into its memory. To program a preset, adjust the
heat and/or stir features to your desired setpoints. Press
and hold one of the presets and the unit will beep indicating
those setpoints have been stored in memory. The presets
will be held in memory, even if the unit is unplugged, until
you choose to override it with another preset.
To activate one of the presets, quickly press the correspon-
ding number and the stir and heat features will automatical-
ly adjust themselves.
It may be helpful to set one of the presets at “OFF” “OFF.”
This way, the heating and stirring can be shut off quickly.
No. 2 pencil may be used to gently mark up writable preset
surface.
Heating Metal Vessels and
Sand Baths
Metal vessels and sand baths cannot be heated on most
solid aluminum tops because of the tendency for the metal
and the sand to reflect heat back into the top, eventually
exceeding the maximum temperature rating for an alu-
minum top. Because of its advanced electronic control, the
SUPER-NUOVA is capable of precisely regulating the top
plate temperature. Metal vessels and sand baths may be
heated safely without danger to the aluminum top.
Setting the Timer
The timer function on the SUPER-NUOVA can be set to
shut off stirring, heating or both. The timer can be set for a
desired number of hours (1, 2, 4, 8 or 12) or for a non-spe-
cific period of time (Infinity symbol). To set the timer, use
the right and left arrows until the light above the number
corresponds to the desired time. The default setting is turn-
ing off heating only. To change this setting, see “Service
and Calibration/Timer Shutdown.”
OPERATION

17
OPERATION
If at any time you wish to reset the timer, press the right
or left arrow keys until the indicator light corresponds to
your desired time. The unit will beep indicating it has
been reset.
One minute before shutdown, the unit will beep three
times and flash the 1 hour light. The unit will beep three
more times to indicate it has timed out.
Power Interruption Protection
If an interruption in power supplied to the SUPER-NUOVA
occurs, the unit will continue to operate normally, as long
as the interruption is no longer than 5 seconds. If the
interruption is longer than 5 seconds, the unit’s power will
be off once the facility power is restored.
Using the Probe with the
Temperature Display for
Stirring-only Applications
On stirring hot plate models, the probe can also be uti-
lized to monitor the actual temperature of your solution
when you want to stir the solution without heating. The
unit must be changed to “Thermometer” mode in order to
perform this operation. See “Service and Calibration/
Thermometer Mode.” To use the probe without heating
the solution, turn the knob counterclockwise until the dis-
play indicates "OFF.” The element will not supply heat to
the top plate.
Note
The display on the plate will indicat-
ed temperatures from 0 to 650°C
when displaying temperature from a
probe. If the actual temperature is
below 0°, the display will still read 0.
If the temperature is higher than
650°, the display will still read 650.

RS232 Output
An RS232 port is available on the SUPER-NUOVA to output
elapsed time, speed, and temperature data. The data is print-
ed once every second when the unit is powered on (displays
on). A comma separates each piece of data so that it may
easily be imported into a spreadsheet as CSV (Comma
Separated Values). The actual data stream sent every sec-
ond consists of: Elapsed Time, Stirring Setpoint, Actual
Stirring Speed, Heating Setpoint, Actual Temperature. (Actual
temperature refers to top plate temperature, or remote probe
temperature if a probe is being used.)
Elapsed time is a 1 second counter that rolls over to zero
again every 12 hours (43,200 seconds). The speeds are
given in RPM, and the temperatures are given in degrees
Celsius. When the unit is first powered on (displays turn on)
a header will print indicating the columns.
In order to communicate with the SUPER-NUOVA, the com-
puter connected to it needs to be set with the following
parameters:
• BITS PER SECOND: 57,600
• DATA BITS: 8
• PARITY: NONE
• STOP BITS: 1
• FLOW CONTROL: NONE
Also, the first time a unit is plugged in, a paragraph of diag-
nostics information will be sent via RS232 and can be viewed
with a terminal program. An example of the data that is sent
is:
Software Version: 1.00
Stir Hours: 0
Heat Hours: 0
Calibration Set Point: 70
Calibration Offset: 0.0
Stir Hours and Heat Hours are kept internally in 1 minute
increments and displayed to the nearest hour. The
Calibration Set Point is the temperature that the unit was cali-
brated at when calibration was performed. The Calibration
Offset is the offset determined at the calibration temperature.

Using HyperTerminal w/RS232
With HyperTerminal you can store the RS232 output data
of a SUPER-NUOVA on a PC. NOTE: Other terminal
programs that capture RS232 data can be used as well.
In order to follow this procedure, you must have:
•Microsoft Windows 95‚ or greater with
HyperTerminal installed (it is available from the
Windows installation CD if not installed already).
•APC that has an available 9 pin DB-9 RS232
connector.
•WHX18 (Accessory) – PC to hot plate communi-
cations cable – Connect it from the back of the
hot plate to the communications port desired.
To Setup HyperTerminal:
1. From the START menu of Windows‚ select
ACCESSORIES, COMMUNICATIONS, HYPER-
TERMINAL
2. Type in a name (example: SuperNuova) that
you would like to refer to the connection by in
the NAME box. You may also select an icon if
you would like. Then select OK.
3. Select the RS232 port that you plan to use to
connect to the hot plate (typically Com 1 or Com
2). Then select OK.
4. Under port settings, select the following:
• BITS PER SECOND: 57,600
• DATA BITS: 8
• PARITY: NONE
• STOP BITS: 1
• FLOW CONTROL: NONE
Then Select OK.
OPERATION

5. Select FILE, SAVE AS, and save this setup
wherever you would like it to be located (if you
would like it on the Desktop, select Desktop)
and select SAVE. You will be able to run
HyperTerminal with this setup in the future by
just double-clicking the icon if you put it on the
Desktop.
6. The setup of HyperTerminal is now complete,
you can view the past data, but the program will
only allow you to see the past 500 lines in its
buffer. To capture data permanently follow the
Capture with HyperTerminal Instructions below.
To Capture Data With HyperTerminal
1. Start HyperTerminal by double-clicking on the
Icon created in the Setup Procedure above.
2. Select TRANSFER, CAPTURE TEXT. Select
the Folder and File name you would like to use
to refer back to this data (example:
C:\SuperNuova\ Test1.txt). It is important to use
the txt extension so that when you double-click
on the file at a later date, it will automatically
open in a text viewing program, or it use the csv
extension and it can be opened in a spread-
sheet such as Excel.
3. The hot plate can be operated and the data will
be stored (it is still viewable on-screen) to the
file that was setup in the previous step.
4. The data file must be closed at the end of the
day (or the end of the capturing session) by
selecting TRANSFER, CAPTURE TEXT, STOP.
The data file must be closed before shutting
down the computer also.
5. The program may be exited by selecting FILE,
EXIT. Select YES to the question “ARE YOU
SURE YOU WANT TO DISCONNECT NOW?”.
