Description

The LCD Digital Control 4-Inch Heating Magnetic Stirrer (2024 Model) is a compact and high-performance laboratory instrument designed for simultaneous heating and mixing of liquid samples. Equipped with a durable 4-inch glass ceramic work plate (100 × 100 mm), the device provides excellent resistance to strong acids, alkalis, and high temperatures while remaining easy to clean after reagent or solvent spills.

The magnetic stirrer supports a maximum stirring volume of up to 10 liters (H₂O) and offers a precise stirring speed range of 50–1500 rpm with 1 rpm increments. The brushless DC motor ensures stable stirring performance, low noise operation, and long service life without maintenance. The integrated LCD display clearly shows real-time and set values for speed, temperature, and time, allowing intuitive operation and accurate experimental control.

The heating plate provides a temperature range from room temperature up to 550 °C with 1 °C adjustment increments. When used with the included high-precision PT1000 external temperature sensor (±0.2 °C accuracy), the system enables accurate monitoring and control of sample temperature during heating and mixing processes.

For enhanced safety, the instrument includes multiple protective functions such as residual heat warning above 50 °C, adjustable safety temperature limits, overheating protection at 580 °C, and dual independent safety circuits that continuously monitor the system. If abnormal conditions occur, the device automatically stops heating and displays an alert.

The corrosion-resistant metal housing improves heat dissipation and durability, while the raised waterproof edge and drainage platform help prevent liquid infiltration into internal components. The timer function supports programmable operation from 1 minute to 99 hours 59 minutes, automatically stopping heating when the countdown ends while maintaining stirring to protect samples. With RS232 connectivity for computer control and included temperature sensor and support clamp, this heating magnetic stirrer offers reliable and precise mixing and heating for modern laboratory environments.

Features

The ceramic-coated plate offers excellent corrosion resistance, capable of withstanding strong acids, strong alkalis, and high temperatures. It is easy to clean spilled solvents, oils, or other contaminants.
The corrosion-resistant full metal housing provides good heat dissipation and reliable fire protection.
The efficient drainage platform and raised waterproof edge prevent liquids from entering the machine and corroding internal electronic components.
Selected high-temperature resistant strong magnets provide powerful stirring force, suitable for mixing viscous liquids.
The safety lock prevents accidental changes to the operating status.
Buzzer: When a fault occurs or the timer countdown ends, the buzzer emits a “beep beep beep” alert sound.
Residual heat warning function: When the plate temperature exceeds 50°C, heating is turned off and the screen displays a flashing “HOT” warning. Even after power-off, the display continues to flash “HOT” to indicate high temperature.
Dual independent safety circuits continuously monitor the device. In the event of overheating or sensor failure, the machine shows an error and stops heating. If a short circuit occurs, the power is automatically cut off to ensure operator safety.
The brushless DC motor is spark-free, long-lasting, low-noise, maintenance-free, and runs smoothly.
The LCD displays both set and real-time values for speed, time, and temperature, providing clear and intuitive readouts.
Timer function: Settable from 1 minute to 99 hours 59 minutes. When the countdown ends, heating stops but stirring continues, preventing thermal damage to samples.
Remote control function is available, allowing connection to a computer.
Safety temperature can be preset.

Applications

Chemical Reaction Mixing: Suitable for heating and stirring chemical reaction mixtures in research and analytical laboratories.
Solution Preparation: Ideal for dissolving solids, preparing buffers, and mixing reagents in chemistry and biochemistry experiments.
