Professional Round Top Hotplate-Stirrer with NIST Traceable Certificate, 120V


  • Products with the TUV symbol assure you that the product meets certain safety standards and performance criteria set by the International Electrotechnical Commission


  • Excellent temperature uniformity
  • LED display for temperature, speed, and time
  • Cool touch, chemical resistant housing
  • Includes RTD temperature probe kit
  • 5 year industry leading warranty

Talboys Professional Round Top Hotplate-Stirrers are designed for applications that require exceptional accuracy, stability, and repeatability. Exclusive safety features help protect operator and sample. Enhanced microprocessor control offers an external RTD probe option that delivers superior temperature control of the sample. Stirring function, with continuous duty motor and powerful magnet, maintains set speed even under changing load or viscosity. Separate LED displays for temperature, speed, and time allow user to view all settings at once.

Hotplate-Stirrer is supplied with a 1.5" (3.8cm) PTFE coated stir bar. Hotplate-Stirrer is also supplied with a probe kit which includes an 8" (20.3cm) stainless steel PT1000 RTD temperature probe, 12" (30.5cm) flex arm, and interchangeable 3-prong clamp head, 2-prong clamp head and spring clamp head. Unit includes a 5 year, industry leading limited warranty on parts and labor.

Operating Conditions: Hotplate-Stirrer can be run in conditions from 5 to 40°C (41 to 104°F), 20% to 80% relative humidity, non-condensing.

NIST Traceable Calibration Certificate provided by Troemner's ISO/IEC 17025 accredited laboratory. Multiple data points within the temperature and speed range, and time function are reported on the certificate with the associated uncertainties.

Operating & Safety Features
Microprocessor ControlAdvanced electronics regulate both heating and stirring and bring samples to temperature quickly and efficiently. Temperature measurement is controlled more accurately by utilizing an internal RTD. Speed is precisely controlled, and provides consistent stirring at all speeds. Powerful continuous duty motor delivers dependable and reliable stirring.
Control PanelTouch pad controls with easy-to-read, independent LED displays for temperature, speed, and time allow operator to view all settings at once. Provides repeatable and accurate results every time and is easily visible from outside fume hoods or across lab benches. Shows set-point and actual temperature. Timer will display elapsed time or, when programmed to user defined limit, will shut off unit when time reaches zero. Display will show last used settings, even after power has been turned off.
Top Plate Material5.3" (135mm) diameter top plate is durable and will not crack. Accepts optional Talboys base plate that holds a variety of block options for holding multiple samples at one time.
Built-In Support Rod HolderRear housing features an off centered, built-in support rod holder with locking knob that accepts the probe kit.
Low Profile DesignTakes up minimal space and fits easily into fume hoods. Spill-resistant design channels fluids away from internal components.
Cool Touch HousingHousing is made of a heat resistant polymer that is not only cool to the touch, but is also chemical resistant.
Hot Top IndicatorFor additional safety, hot symbol warning light is illuminated when heat is turned on and remains on until top plate cools down.
Stir ProtectionIf stirrer motor stops or fails, unit will automatically shut down heater.
Speed Ramping FeatureSlowly increases motor speed for improved safety and enhanced coupling. Avoids splashing, improves spin bar control, and provides excellent low end speed control.
Maximum Temperature Limiting(plate over temperature limit) Ensures plate temperature will never exceed users programmed set temperature limit, allowing for control of samples with sensitive flash points.
Audible AlarmIn timed mode, alarm will sound when time reaches zero or when unit reaches set-point temperature.
Probe ProtectionIf probe disengages from sample, unit will automatically shut off heater.

Voltage Explanation

For use in the United States, typical voltage is 120V. 120V units are supplied with standard 3-prong grounded plug.

For use outside the United States or for 230V applications, 230V units are supplied with a Euro type plug. If you require a different plug type, please specify the part number listed below in the comments when ordering. For plug types not displayed below, please contact Inside Sales at +1.856.686.1600 or via email at All plugs supplied are standard IEC 320 type connector.
