VELP MULTI-HS Digital Multi-Position Hot Plate Stirrer
The VELP MULTI-HS Digital series is a high-performance multi-position hotplate stirrer designed for simultaneous stirring and heating of multiple samples with precision and consistency. Available in 6-position and 15-position configurations, it delivers uniform temperature up to 120 °C across all positions, ensuring reproducible results in high-throughput laboratory workflows. Powered by VELP brushless motor technology, each position maintains constant speed independently, supported by SpeedServo™ feedback to compensate for viscosity changes during operation. The durable CerAlTop™ plate provides excellent heat distribution, chemical resistance, and easy cleaning, making it ideal for continuous laboratory use. A user-friendly digital interface allows full control of speed, temperature, timer, and auto-reverse functions, enabling unattended operation with maximum reliability. Designed and manufactured in Italy, the MULTI-HS series is a dependable solution for laboratories requiring efficient, parallel sample processing.
