Advanced stirrer with SmartChuck tech, IP54 protection, and constant torque control.
The VELP OHS 20 Digital Rod Stirrer is meticulously engineered to uphold the highest safety standards in laboratory settings. Featuring a robust sealed casing and an IP54 protection degree, this equipment promises longevity and resilience, even in harsh environments. A 3-year extended warranty assures uninterrupted operation within your laboratory.
With its powerful brushless motor and microprocessor control, the VELP OHS Series demonstrates superior performance compared to conventional shaft stirrers. The SpeedServo feedback system ensures constant torque at any speed, crucial for the reproducibility of analyses.
Innovative SmartChuck Technology simplifies the insertion and removal of stirring rods. The process, traditionally requiring two hands, is now streamlined with a one-handed operation—no additional tools required. If the protective ring is opened during analysis, the device halts stirring and displays a safety alert.
OHS Digital models are built for maximum protection and security. The IP54 rating protects against corrosion, enhancing performance in challenging environments. Activation via pressure prevents accidental start-ups, with a gradual approach to set speed. Integrated safety controls automatically stop stirring in cases of overload, overheating, or short circuits.
Incorporating an integrated timer, the OHS Digitals allow precise scheduling to meet laboratory needs. Easily programmable from 1 minute to 99:59 hours via a dedicated button, it enables independent reaction processes.
The models offer choice between Digital and Advanced control panels tailored to your preferences:
User-friendly and ergonomic, these tools feature an intuitive control panel with SmartChuck facilitating single-handed operations and rod changes.
Specifications include a mandrel opening from Ø 1 to 13 mm and a permissible stirring rod diameter for pass-through of up to 8.5mm. VELP ensures peace of mind and security in laboratory environments with:

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
