Large Capacity Magnetic Stirrer
The Whirl-pak LACHOI Large Capacity Magnetic Stirrer is a heavy-duty laboratory instrument designed to handle high-volume mixing tasks that exceed the limits of standard stirrers. Engineered for stability and power, it is capable of stirring up to 20 to 50 liters of liquid (depending on the specific configuration), making it an ideal choice for pilot plants, large-batch buffer preparation, and industrial-scale research.
Description
Description
The LACHOI Large Capacity series is built to bridge the gap between benchtop experimentation and small-scale production. While standard stirrers struggle with the torque required for high-volume or high-viscosity samples, this unit utilizes an extra-strong magnetic drive and a high-torque brushless motor to ensure consistent rotation even in deep vessels.
Its expansive work surface is designed to accommodate oversized carboys, heavy glass carboys, and stainless steel containers, providing a steady and vibration-free mixing environment for extended periods.
Key Features
Massive Stirring Capacity: Specifically designed to support and mix large volumes, typically ranging from 20L to 50L, ensuring uniform distribution in large containers.
High-Torque Brushless Motor: Equipped with a powerful DC brushless motor that provides constant speed under load, produces minimal heat, and requires zero maintenance.
Precision Speed Management: Features a wide speed range (often 50–1500 RPM) with smooth acceleration to prevent “stir bar decoupling” or splashing in large vessels.
Durable, Oversized Top Plate: The large-format platform is often made of stainless steel or nano-ceramic coated materials, providing the structural integrity to hold heavy loads while remaining resistant to aggressive chemicals.
Intelligent Digital Interface: Includes a clear LCD or LED display for precise monitoring of speed and time. Many models feature a timer function (up to 99 hours) for automated long-term mixing.
Safety & Stability: Built with a low center of gravity and non-slip feet to prevent “walking” or vibration during high-speed operation. It also includes over-torque and over-speed protection to safeguard the motor.
Strong Magnetic Coupling: Uses high-grade rare earth magnets to maintain a secure lock with large stir bars (up to 100mm in length), ensuring the bar doesn’t “spin out” even at maximum capacity.
