OHS 60 Advance Overhead Stirrer
Analogical overhead stirrer with 80 Ncm torque able to stir up to 40 L.
Safety and resistance for your lab
- The resistant sealed housing and theĀ IP 54 Protection RatingĀ guarantee durability even in the most aggressive environments.
- Integrated overload, overtemperature, and overcurrent safety alarms will preserve the performance over time by stopping the stirringĀ
- Safe start and stop knob operation andĀ lock keyĀ avoid unintended start up and changes of the working conditions.Ā
- IntegratedĀ vibration sensorĀ with differentĀ levels of sensitivity will stop the operation and inform youĀ to be sure that your OHS is stable and properly fixed.
Best-in-class Stirring Power
The electronic controlled brushless motor of the OHS 60 Advance stirs up toĀ 40 lĀ (H2O) with a maximum torque ofĀ 60 Ncm, and ensures the longest lifespan.Ā
SpeedServoTMĀ torque compensation technology keeps the speed constant automatically adjusting to viscosity changes. Set the OHS 60 Advance electronic speed control from 30 to 2000 rpm.
Constant torque at any speed
The torque is stable throughout the whole speed range, ensuring stirring at maximum torque even at the highest speed.
This is a very important parameter for the reproducibility of your tests.
SmartChuckā¢ simplifies shaft accommodation
With two simple operations, you can unlock the protection ring to drive the shaft in and out with maximum ease.
The opening of the ring during the stirring process will automatically block the analysis and the instrument informs you for maximum safety.
Intuitive and precise
Interact with the OHS Advance from the real-time graph showing speed, torque and temperature of your test. Ā
The OHS 60 Advance works unattended thanks to theĀ timerĀ settable from 1min to 99.59h. Define andĀ program your operating methodsĀ that are ideal for demanding tasks where ramps and interval operation are required.
Keep Temperature Under Control
Constantly monitor the temperature of your reaction and set the instrument to reduce speed or interrupt the task if the temperature reaches a defined value. This is important when you want to avoid that exothermic reactions will interfere with your analysis.Ā
The advantages of OHS Advance connectivity
VELP ErmesĀ cloud platform allows to control the OHS Advance from PC, smartphone and tablet through a simple and intuitive web interface. With this platform designed by VELP, it is possible toĀ activate the stirring, set aĀ timer, set aĀ methodĀ (among those saved on the device), download and shareĀ reportsĀ with a click.
For the applications in the pharmaceutical, biotechnology and life science sectors, VELP Ermes can manage OHS Advance located in clean-rooms or other controlled environments, without the need of long safety procedures.
With the OHS/CotrollerSoftTMĀ software, VELP offers the possibility to all laboratories that can’t benefit from cloud services, a valid alternative with USB connectivity.
Choose the right stirring shaft for your application!
Ā
Overhead stirrers require stirring shaft for precise working. Choosing the correct stirring shaft is an important step to obtain the best stirring performance.Ā
It is important to evaluate the characteristics and the effects on the fluid of the stirring shaft, together with the volume and viscosity:Ā
- Desired type of flow: Axial, Tangential, Radial;Ā
- Speed range of your applicationĀ
Contact a VELP Specialist that will guide you to choose the correct shaft for your sample and application!Ā
VELP H-Stand ensure stability and resistance for lab bench application
Ā
Ā
Ā
VELP H-Stands are the ideal solution when the overhead stirrer is working on laboratory benches.Ā
We have designed our H-Stand to guarantee the maximum stability thanks to the H-shape of the base and the maximum resistance choosing premium materials such as aluminum and stainless steel, properly treated in order to resist to chemicals and corrosion.Ā
The Telescopic H-Stand facilitates the daily operations being easy-to-use when raising and lowering the overhead stirrer from your sample.Ā
