LACHOI OES Electric Overhead Stirrer

The LACHOI OES series is the high-value companion to the OS series, focusing on reliable daily performance for common laboratory tasks. It utilizes a high-quality DC motor (often permanent magnet or brushless depending on the sub-model) to deliver high torque and steady speeds. The OES model is particularly noted for its user-friendly interface and robust safety mechanisms, ensuring that even prolonged mixing sessions remain stable and safe. Its design includes a “through-shaft” system, which allows users to adjust the height of the stirring impeller without needing to disassemble the entire setup or move the heavy motor head, providing significant flexibility for different beaker and flask sizes. Key Features Steady Speed Performance: Provides a wide speed range (typically 50–2000 RPM) with stepless adjustment, allowing for both gentle homogenization and high-speed dispersion. Intuitive LCD/LED Display: Equipped with a clear digital screen that displays set and actual speeds, ensuring high repeatability for sensitive experiments. Constant Speed Torque Control: Features an internal microprocessor that automatically adjusts power to maintain a constant speed, even if the sample’s viscosity changes during the mixing process. Safety & Overload Protection: Includes an automatic shut-off feature that triggers if the motor encounters excessive resistance or overheating, protecting both the equipment and your sample. Stable Start-up Technology: Engineered with a “soft start” function that gradually accelerates the stirring rod to the target speed, effectively preventing sample splashing or container tipping. Flexible Clamping Chuck: Features a high-quality, adjustable chuck that accommodates a variety of stirring rod diameters (usually 0.5–10mm), making it compatible with propellers, paddles, and anchor-style impellers. Memory Function: Automatically saves the last used parameters, allowing for quick restarts and consistency across multiple batches.
