20L-100L Lab Overhead Stirrer Lab Mixer for Processing Chemicals LCD Core Motor

Product Application:
The overhead mixer features a self-locking chuck and can be equipped with an optional square lifting clamp developed in-house. It boasts a large LCD display with adjustable speed and time settings, suitable for mixing solid-liquid, liquid-liquid, or medium-to-high viscosity samples. Primarily used in scientific research, pharmaceuticals, chemical engineering, petrochemicals, cosmetics, food processing, and biotechnology fields.


Key Features:
● LCD display with coarse speed and time adjustment; allows fine-tuning of operating time during operation;
● Speed range: 30-2200 rpm, supports constant speed control with adjustable high/low speeds;
● Utilizes a DC brushless motor for extended safe operation and superior performance;
● Overload and motor protection automatically cuts circuit and triggers alarm during overload, short circuit, or anomalies to ensure experimental safety;
● Features a stirrer penetration hole, eliminating the need to adjust instrument height—only the stirrer rod position requires adjustment;
● Torque automatically adjusts based on sample viscosity for convenient operation;
● Multiple stirrer blades and brackets available.
● Aluminum metal casing: ensure the mechanical accuracy for long-term use;ensure the electrical performance for continuous use; ensure stable operation and low noise.
● Power-increasing speed-change mechanism:The output torque of low-speed operation is doubled; it can meet the mixing of large capacity and high viscosity media.
● Stepless variable speed control: arbitrary selection of experimental running speed; wide application range and convenient speed regulation.
● Stirring rod rolling head: It is convenient to roll the stirring rod; suitable for a wide range of diameters;
● Open rack: wide selection of media containers; offset mixing is easy.
