Ohaus Overhead Stirrers Achiever™ 5000 e-A51ST200

The Ohaus Achiever™ 5000 e-A51ST200 Overhead Stirrer is engineered for the most demanding laboratory mixing tasks. With a high torque of 200 Ncm and the ability to handle viscosities up to 100,000 mPa·s, this stirrer is ideal for challenging and high-volume applications. Its dual speed range enhances versatility, while the digital interface and programmable timer ensure accurate, hands-free operation.

Features

1. Dual-speed range for flexible mixing

Offers two operating modes: low-speed range (6–400 rpm) for highly viscous materials, and high-speed range (30–2,000 rpm) for more dynamic mixing, adapting to a variety of sample types.

2. Exceptional torque and volume capacity

Delivers up to 200 Ncm torque with a 100-liter mixing capacity, making it suitable for industrial-scale and high-viscosity applications.

3. Digital control with LED display

Provides precise speed adjustment, operational visibility, and intuitive navigation for enhanced user control.

4. Wide chuck and shaft compatibility

Features a 1–13 mm chuck range and supports shafts up to 8.5 mm in diameter, ensuring compatibility with a broad range of stirring accessories.

5. Long-timer operation

Built-in timer programmable from 1 minute to 99 hours, 59 minutes allows extended unattended mixing processes with consistent results.

6. Rugged and safe for demanding labs

IP54-rated design ensures protection from dust and splashes, while cNemkous certification guarantees reliable and safe performance in regulated environments.
