ACHIVER OVERHEAD STRIRRER Ohaus e-A51ST200

ACHIVER OVERHEAD STRIRRER Ohaus e-A51ST200

The ACHIVER OVERHEAD STRIRRER Ohaus e-A51ST200 is an ultra high-torque digital overhead stirrer engineered for the most demanding laboratory and pilot-scale mixing applications. Designed to handle extremely high-viscosity materials and large working volumes, this model delivers exceptional torque, precise speed control, and long-term operational stability for critical mixing processes.

As the most powerful model in the Achiever Overhead Stirrer series, the e-A51ST200 is built for mixing dense, thick, and highly resistant materials that require slow, controlled rotation or high-speed agitation. Its dual-range speed capability allows users to operate at very low speeds for heavy loads or switch to higher speeds for efficient homogenization. The digital control system and clear LED display ensure accurate parameter monitoring, while the IP54-rated housing provides protection for safe use in harsh laboratory environments.
