VELP DLH Digital Overhead Stirrer The VELP DLH is a powerful digital overhead stirrer designed for precise mixing of medium to high viscosity samples in demanding laboratory environments. Delivering up to 80 Ncm of torque with electronic speed regulation from 50 to 2000 rpm, it ensures reliable and consistent performance for volumes up to 40 L and viscosities up to 50,000 mPa*s. The bright digital display provides real-time monitoring of key parameters including set speed, actual speed, torque, and timer, allowing full control over the mixing process. Equipped with a programmable timer up to 999:59 minutes with automatic shut-off, the DLH enhances repeatability and workflow efficiency. Its advanced SpeedServo™ feedback system maintains constant speed even when sample viscosity changes, while the smooth start function minimizes splashing. Built for durability, the DLH features a robust long-life motor, automatic shut-off in case of blockage, and full overload, overcurrent, and overheating protection. The lightweight technopolymer and epoxy-painted aluminum construction ensures excellent chemical resistance, making the DLH a dependable solution for laboratories handling more demanding mixing applications.
