Digital Heavy Duty Overhead Stirrer 50-2000 rpm B-One

B-ONE BOS-40T / BOS-60T Heavy Duty Overhead Stirrer – High-Torque Mixing for Viscous and Large-Volume Samples

The B-ONE BOS-40T and BOS-60T Overhead Stirrer are designed for heavy-duty, high-viscosity mixing in laboratory and industrial applications. With a powerful torque output of 40 N·cm (BOS-40T) and up to 60 N·cm (BOS-60T), these models are built to stir large volumes of thick materials smoothly and safely. Both units feature LCD digital displays, a broad speed range of 50–2000 rpm, and support multi-segment programming, allowing users to perform complex procedures with ease.

Additionally, their DC permanent magnet motors ensure stable, low-noise operation, while built-in safety features like overload protection and automatic memory functions make them ideal for high-precision environments.

Product Features

• High Torque Performance
  The BOS-40T delivers 40 N·cm of torque, while the BOS-60T provides a powerful 60 N·cm, supporting efficient stirring of even the thickest samples.

• Precise Speed Control
  Both models offer a speed range of 50–2000 rpm, with 10 rpm accuracy, making them suitable for both delicate and intense mixing.

• Large Volume Capacity
  The BOS-40T handles up to 20 liters, while the BOS-60T supports mixing volumes up to 40 liters, ideal for large-batch sample processing.

• High Viscosity Handling
  Designed to manage viscosities up to 15,000 mPa·s (BOS-40T) and 50,000 mPa·s (BOS-60T), making them perfect for mixing resins, pastes, and polymers.

• User-Friendly LCD Interface
  View set and actual speed in real time for intuitive operation and precision monitoring.

• Automatic Safety Features
  Includes overload protection and stable soft-start functions to prevent overflow and protect equipment.

• Memory & Multi-Stage Programming
  The system automatically remembers the last used parameters and supports multi-segment control for complex stirring protocols.

• Quiet and Stable Operation
  With no-load noise <65 dB and load noise <70 dB, they provide smooth and quiet mixing—ideal for shared lab spaces.
