OHS systems are designed with an emphasis on superior safety regulation. A sturdy sealed casing guarantees long-term usage even in harsh environments, with an IP54 protection degree ensuring durability. Enjoy seamless lab operations under a guaranteed three-year extended warranty.
Steady Torque Regardless of Speed
Powered by an exceptional brushless motor and microprocessor control, the VELP OHS Series Overhead Stirrers offer unparalleled performance. The exclusive SpeedServo feedback system ensures a consistent torque at any speed, even at peak levels, which is critical for accurate, reproducible analysis.
Innovative SmartChuck Technology: Easy Stirring Rod Insertion and Removal
The laborious two-handed stirring rod change is now a thing of the past. With SmartChuck™ technology, changing your stirring rod is a simple, convenient, one-handed task. Two straightforward steps allow stir rod replacement, and stirring operations are automatically interrupted with a safety message displayed if the protective ring is opened during an ongoing analysis.
Enhanced Protection and Security
The advanced OHS system promises superior safety standards. Its IP54 protection degree safeguards the equipment from corrosion, providing consistent performance in harsh work environments. The stirrer is pressure-activated to prevent accidental startups, while numerous sensors and safety controls shut down stirring operations in case of overload, overheating, or short circuit.
Integrated Timer for Work Scheduling
With built-in timers, OHS Digital equipment allows stirrer programming to suit the needs of independent reactions. Timer settings are a breeze, adjustable between 1 minute and 99 hours 59 minutes.
For maximum convenience, OHS offers two distinct control panels, Digital and Advanced, to suit your lab’s specific needs. The Digital option provides precise speed settings, torque indicators and an integrated timer, while the Advanced option offers complete information at a glance, with intuitive controls and real-time graphs.
Simplify your operations with user-friendly tools, including an effortless rod change with a single hand, thanks to SmartChuck.
