Description by the supplier

The Overhead Stirrers (OHS) are engineered prioritizing the highest safety protocols. The resilient, sealed casing along with IP 54 protection ensures long-lasting durability, promising resilience in even the most demanding environments. Expounding on the reliability, a 3-year extended warranty underlines the commitment to continuous, trouble-free operation in your laboratory.


Achieving a Constant Torque across all Speed Levels:

Powered by a robust brushless motor coupled with a microprocessor control, the OHS series from VELP delivers unparalleled performance. The significant differentiation is exhibited when compared to conventional shaft stirrers. The SpeedServo system ensures constant torque no matter the speed, including maximum. Having a consistent torque is essential for reproducibility of analysis.


SmartChuck Technology offers Simplicity in Usage:

Implementing or replacing the stirring rod often involves using both hands, risking the rod falling into the liquid. With SmartChuck™ technology, rod replacement is made efficient and user-friendly, requiring only one hand and no special accessories. Two easy steps allow you to unlock the protective ring and replace or remove the stirring rod. A safety feature is engaged if the protection ring is opened mid-analysis, stopping the stirring and displaying an alert.


Promising Maximum Safety and Security:

The advanced OHS models uphold the highest safety standards. The IP54 protection assures maximum instrument safeguarding against corrosion and superior performance in challenging work environments. The stirrer is pressure-actuated, preventing inadvertent startups and reaching the set speed gradually. Multiple sensors and safety controls deactivate stirring in case of overload, overheating or short circuit.


Equipped with Integrated Timers for Scheduling:

OHS Digital models include inbuilt timers to schedule stirring as per your laboratory needs, enabling independent reaction processes. The timer setting is quick and easy, involving pressing a dedicated button to select a time interval between 1 min and 99:59 hours.


OHS models provide the choice of two user-friendly control panels - the Digital and Advanced, designed to suit laboratory requirements.


- Digital: Accurate speed settings, torque indicator, inbuilt timer.

- Advanced: Comprehensive glance-worthy information, intuitive, real-time graphics.


The interactive control panel is equipped with SmartChuck, enabling operating and rod changing with just one hand, easily and effortlessly.


- Mandrel Opening: Ø ranges from 1 to 13 mm

- Stirring Rod Diameter for Pass-Through: Up to 8.5mm


Velp products ensure tranquility and security in your laboratory setting.

Heidolph 036110233 Hei-PLATE Mix 'n' Heat Ultimate Hotplate Stirrer, 135mm Plate-cover
Heidolph 036110233 Hei-PLATE Mix 'n' Heat Ultimate Hotplate Stirrer, 135mm Plate

Heidolph 036110233 Hei-PLATE Mix 'n' Heat Ultimate Hotplate Stirrer, 135mm Plate The Heidolph 036110 (more)233 Hei-PLATE Mix 'n' Heat Ultimate Hotplate Stirrer, 135mm Plate paves the way for future-oriented working practices: thanks to its equipment with numerous interfaces, it meets all requirements for digitalization and network. The RS232 and USB B interfaces allow control via our Hei-Control software, free of charge, as well as our Hei-PROCESS solution. With the LAN interface, you can directly integrate the device into a network, whereas the USB A interface located at the front allows data logging via USB stick. Use the USB C interface and combine the magnetic stirrer with the electric Heidolph Lab Jack to work even more comfortably and securely. For controlling the temperature, you can choose between three heating modes: FAST for a particularly quick heating, as well as PRECISE and PRECISE+ for a particularly exact control of your target temperature without overshoot - this is how sensitive samples are optimally protected. Therefore, the device is compatible with the temperature sensor Pt1000 as well as the double sensor Pt1000 that allows the measurement in your sample and in the bath liquid simultaneously. The possibility to program ramps and to create profiles gives you full control and increases the precision and reproducibility of your experiments. For the stirring speed, there is a three-stage setting (start-up behavior). Furthermore, you can set the rotational direction of the magnetic stirring bar and benefit from the automatic stir bar detector. As a result, your sample is optimally stirred at any time, even when there are irregularities while stirring. This magnetic stirrer is equipped with the most important safety features. The large safety distance between the heating plate and the control panel, as well as the visual residual heat indicator at temperatures 50°C, protect against burns. The patented Kera-Disk® plate made of anodized aluminum is chemical-resistant, scratch-resistant and has a diameter of 145 mm. This unique size makes it suitable for use with many accessories and samples on a small footprint. Moreover, the material used allows the fastest heating times.
