LACHOI OS Electric Brushless DC Motor Overhead Stirrer
The Whirl-pak LACHOI OS Series Overhead Stirrer is a high-torque laboratory mixer designed for high-viscosity samples and large-volume agitation. Driven by a maintenance-free brushless DC motor, it provides constant stirring speeds even as liquid thickness changes, making it ideal for intensive mixing in chemical synthesis, pharmaceutical formulation, and cosmetic manufacturing.
Description
Description
The LACHOI OS Electric Overhead Stirrer is engineered to handle demanding mixing tasks that magnetic stirrers cannot. By utilizing a cantilever design with a through-shaft chuck, it allows for easy adjustment of the stirring paddle height to suit various vessel sizes. The Brushless DC (BLDC) motor ensures that the unit remains cool during continuous operation while delivering the significant torque required to move thick emulsions, gels, and suspensions.
Equipped with microprocessor control, the OS series maintains a precise RPM, automatically compensating for torque fluctuations to ensure consistent results across every batch.
Key Features
Advanced Brushless DC Motor: Offers silent operation, high efficiency, and a long service life with zero maintenance. It generates minimal heat, which is critical for temperature-sensitive samples.
Constant Speed Technology: Automatically adjusts torque output to maintain the set RPM even if the sample viscosity increases during the reaction.
Intelligent Digital Control: Features a bright LCD screen that displays both the set speed and actual speed simultaneously for real-time monitoring.
Through-Shaft Design: The adjustable chuck allows the stirring rod to pass through the head of the unit, making it simple to change the height of the impeller without moving the entire stirrer assembly.
Safety Protection Systems: * Overload Protection: Automatically stops the motor if the torque limit is exceeded to prevent damage.
Anti-Spill Soft Start: Gradually increases speed to the set point to prevent splashing and sample overflow.
Multi-Segment Programming: (Available on Pro/Upgrade models) Allows users to program complex mixing sequences with varying speeds and durations.
High Viscosity Capability: Designed to handle substances with viscosities up to 50,000–100,000 mPa·s (depending on the specific OS model).
