OHS 60 Advance Overhead Stirrer VELP
Optimal Safety and Reliability for Your Laboratory
The design of OHS Advance is crafted to uphold the pinnacle of safety regulations.
- Its robust, waterproof casing combined with an IP 54 protection rating assures long-lasting durability even in the harshest laboratory conditions.
- Integrated safety alerts for overload, over temperature and over current will sustain the device's performance by halting agitation when necessary.
- The secure handling of the start and stop switch and the lock key deter inadvertent initiations and modifications to the work environment.
- The embedded vibration sensor, equipped with varying sensitivity levels, will halt operation and notify the user, ensuring the stability and proper fixation of your OHS device.
Uninterrupted function is secured and endorsed by an extensive 3-year warranty.
Superior Performance
The OHS Advance is the exemplary solution for demanding tasks requiring viscosities up to 50,000 mPa. Its electronically governed brushless motor, integral to the OHS 60 Advance, stirs up to 40 l (H2O) with a maximum torque of 60 Ncm and guarantees optimal durability.
SpeedServoTM torque compensation technology maintains a consistent speed by auto-adjusting to viscosity fluctuations. Set the OHS 60 Advance's electronic speed control within a range of 30 to 2000 rpm.
Consistent Torque Across All Speeds
The combination of the powerful brushless motor and microprocessor control provide unmatched performance. This illustrates the marked difference between a conventional stirrer and the advanced VELP OHS Series vessel stirrers. The torque remains constant at all speeds, even at the device's maximum. This constant torque is crucial to ensure analysis reproducibility.
SmartChuck Technology: Simplified Stirring Rod Replacement
Regular tasks of changing or removing a stirring rod—often involving fumbling or accidental falls into liquid—become effortless with SmartChuck™ technology. This innovative feature lets you complete the task single-handedly without the need for additional tools. If the safety ring is opened mid-analysis, the device will halt automatically, displaying a safety message.
Accurate and Intuitive Control Panel
The OHS Advance features an intuitive 3.5" TFT display that enables precision setting of working conditions and assurance of reproducible results. Key information is displayed in real-time. You can actively monitor viscosity variations with a resolution of 1 Ncm. Engage with OHS Advance using a real-time graph showing speed, torque, and temperature of your experiment.
Thanks to inbuilt timing functionality, the OHS Advance can operate unsupervised between 1min to 99.59h. Custom operating methods can be set for complex tasks requiring interval operations or gradual changes.
Controlled Temperature Maintenance
OHS Advance comes fitted with a Pt100 temperature probe. Continually observe the temperature of your reaction and set the device to decelerate or halt activities if a predefined temperature threshold is reached—vital to prevent exothermic reactions from interfering with your analysis!
ADVANTAGES OF OHS ADVANCE CONNECTIVITY
Unique to the market, the OHS Advance rod stirrer provides the capability to control and monitor processes via Wi-Fi connectivity through VELP Ermes and via USB.
VELP Ermes cloud platform simplifies remote control of the OHS Advance from your PC, smartphone, and tablet through a user-friendly web interface. Start shaking, set timers, select a stored method, download and share reports with a single click.
For applications in pharmaceutical, biotechnology, and life sciences, the ability to control OHS Advance devices in clean rooms or within other regulated environments eliminates the necessity for lengthy safety procedures.
The OHS/CotrollerSoftTM software offers USB connectability for labs not benefiting from cloud services.
The OHS devices come with two accessible control panel options, Digital or Advanced, to better fit to your lab's specific needs.
- Digital: Precise speed settings, torque indicator, and integrated timer.
- Advanced: Comprehensive data at a glance, an intuitive interface, real-time graphs.
Ease-of-use extends to our SmartChuck system for simple, one-handed rod changes.
- Mandrel opening ranges from 1 to 13 mm.
- Stirring rod diameter for Pass-Through is up to 8.5mm.
VELP products ensure an atmosphere of calm and safety within your laboratory setting.
