FAQs

What is the OHAUS e‑A51ST200 overhead stirrer?

The OHAUS e‑A51ST200 is a digital overhead stirrer from the Achiever™ 5000 series designed for laboratory mixing. It delivers reliable, powerful stirring for liquids up to about 100 L capacity, combining precision control, robust construction, and easy operation for demanding lab and industrial mixing tasks.

What level of performance does this model deliver?

This overhead stirrer operates over a wide speed range (typically 6-400 rpm at low gear and up to 2000 rpm at high gear) with ±1 rpm accuracy, ensuring consistent mixing performance across various viscosities and solution types.

What kind of liquids can it mix?

The e‑A51ST200 handles liquids with a maximum viscosity of approximately 100,000 mPa·s (cP), making it suitable for thicker solutions, dispersions, emulsions, and other challenging mixtures encountered in chemical, biological, and industrial workflows.

How is the stirring speed controlled?

A digital control knob and LED display let users precisely adjust and monitor stirring speed, real‑time torque tendencies, and integrated timer settings, making it easy to achieve repeatable mixing results.

Is this stirrer safe and durable?

Yes, it has a sealed aluminum housing with an IP54 rating that resists dust and splashes, and it features safety protections such as overload and over‑temperature shutoff, ensuring safe, durable operation even in demanding lab environments.

What makes setup and use convenient?

The unit includes a keyless chuck for one‑hand shaft changes without tools and simple knob controls, reducing setup time. A lock button prevents accidental changes in speed during operation.
