OHAUS Achiever™ 5000 Series Overhead Stirrer

Powerful and Reliable Mixing for Demanding Laboratory Applications

The OHAUS Achiever™ 5000 Overhead Stirrers deliver powerful, precise stirring capabilities designed for safety and simplicity across diverse mixing applications. Available in five models with torque ranging from 20 Ncm to 200 Ncm and volume capacity from 25L to 100L, these sealed overhead stirrers feature an IP54 ingress protection rating ensuring safe mixing performance even in the most demanding laboratory and industrial environments. The brushless motor with torque compensation technology provides constant speed and stable torque at any speed, delivering accurate, controlled stirring of viscous liquids with quiet, reliable operation. Speed control ranges from 6 rpm to 2000 rpm (depending on model) with precision accuracy of ±1 rpm, accommodating everything from gentle mixing to vigorous homogenization. The innovative keyless chuck enables quick, one-handed shaft changes without tools, simplifying setup and reducing operator time while the software-controlled speed ramping provides safe stirring to protect both sample and user.

User-Centric Design with Advanced Safety Features

Engineered with laboratory safety as a priority, the Achiever™ 5000 series incorporates a lock button that prevents accidental speed changes and overload sensing technology that automatically shuts off stirring before damaging overload conditions occur. The bright LED digital display shows real-time speed, torque tendency with LED indicator bar, and an integrated timer (1 min to 5,999 min) for precise process control. The sealed aluminium housing with compact design ensures easy handling and portability, while the simple knob control and full protection against overload, overtemperature, and overcurrent conditions make these stirrers suitable for pilot-scale manufacturing and everyday laboratory use. With universal dual voltage (115/230 VAC) operation, optional RS232 communication for system integration, and cNemkous safety certification, the Achiever™ 5000 series is ideal for stirring, dissolving, dispersion, emulsification, and homogenization across food and beverage, cosmetics, paint/coatings, pharmaceutical, chemical, adhesive, plastics/polymer, and cement/construction industries.
