OHS 40 Digital Overhead Stirrer Velp Scientifica

Safety and Resistance for Your Lab

OHS 40 Digital Overhead Stirrer is designed to guarantee the highest safety standards. The resistant sealed housing and the IP 54 Protection Rating guarantee durability even in the most aggressive environments. Integrated overload, overtemperature, and overcurrent safety alarms will preserve the performance over time and stop stirring for maximum safety in your lab.

Safe start and stop knob operation and lock key avoid unintended start-up and changes of the working conditions. OHS 40 Digital ensures continuous operation and is backed by a 3-year warranty extension.

Best-in-class Stirring Power

The OHS 40 Digital is the ideal solution for demanding applications operating with viscosities up to 25,000 mPa. The electronically controlled brushless motor of the OHS 40 Digital stirs up to 25 liters with a maximum torque of 40 Ncm, ensuring the longest lifespan.

SpeedServo™ torque compensation technology keeps the speed constant, automatically adjusting to viscosity changes. Precisely set the OHS 40 Digital from 30 to 2000 rpm, ensuring constant torque at any speed.

The brushless motor and the microprocessor guarantee excellent performance, marking the difference between a conventional overhead stirrer and the VELP OHS Series. 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.

SmartChuck™ Simplifies Shaft Accommodation

The OHS Digital SmartChuck™ technology simplifies the shaft accommodation process. It can be carried out with one hand and does not require any tools, making your life easier. 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.

Easy-to-use and Precise

All the necessary information is available at a glance, and the dedicated Torque Display with 4 LED segments informs about viscosity changes during the operation. The OHS Digital integrated timer allows unattended operations. Program your OHS Digital from 1 minute to 99.59 hours and walk away! The USB interface facilitates software updates if required.
