hotplate stirrer with oversized alnico magnetic material

Hotplate Stirrer

Main Features

1. Adjustable forward/reverse stirring: Motor commutation enables cyclic switching of stirring direction for deep mixing of viscous or suspended liquids.
2. Corrosion-resistant microcrystalline glass interface: Scratch-resistant, acid/alkali-resistant, easy to clean after experiments, aesthetically pleasing and low-maintenance.
3. Large ceramic heating plate: 180×180mm white platform supports large stirrers and ensures thermal balance for high-volume liquids.
4. Insulated heating plate: Composite surface remains safe and insulated even at 380 °C for secure operation.
5. LCD backlit display: Shows set and real-time temperature, time—intuitive, convenient control.
6. Magnetic field enhancement: High-grade Alnico magnets provide strong coupling and stability, even at high temperatures.
7. Dual security system: Heating indicator LED and digital temperature feedback avoid overheating and misuse.
8. Integrated micro-rotary reversing knob: Multi-function knob enables rotary and press switching for efficient operation.

Core Advantages

1. Stronger magnetic coupling: Reliable stirring for viscous or suspended solutions, even at high temperatures.
2. High thermal efficiency & low loss: Insulated heating plate speeds heating and saves energy.
3. Supports large capacity: Stable use with wide-mouth beakers or reaction bottles.
4. Intelligent operation: LCD feedback controller and direction change improve accuracy and user feedback.
5. High reliability materials: Corrosion-resistant glass, ceramic, and magnets extend service life.

Working Principle

1. Stirring: Motor generates a rotating magnetic field (via high-strength Alnico magnet), driving the stir bar for uniform mixing; forward/reverse switching for particle-containing/high-viscosity systems.
2. Heating: Ceramic plate rapidly conducts heat to the container via contact conduction; insulation prevents electrical/thermal leakage.
3. Temperature control: Closed-loop digital controller adjusts output power to maintain stable heating, avoiding temperature fluctuations.

Application Areas

1. Organic/inorganic chemistry: Reflux, crystallization, synthesis, extraction—precise heating and stirring.
2. Biotechnology: Thermostatic enzyme digestion, cell lysis, nutrient solution mixing.
3. Pharmaceutical R&D: Drug dissolution, dispensing, dissolution tests.
4. Food science/environmental engineering: Mixing simulation, solution testing, pollutant dissolution.
5. Teaching labs: Basic heating/stirring for chemistry/biology education.
