Laboratory High Speed Programmable 20l Glass Ceramic Hotplate Electric Mixer Magnetic Stirrer
DMS7-550M LCD Glass Ceramic Heating Magnetic Stirrer with Timer
The ceramic plate has strong corrosion resistance, capable of withstanding strong acids, alkalis, and high temperatures. It is easy to clean solvents, oils, or other contaminants that may accidentally spill.
The corrosion-resistant full metal casing has excellent heat dissipation performance and reliable fire protection capabilities.
The efficient flow platform and waterproof design prevent liquids from entering the interior of the machine, protecting the electronic components from corrosion.
High-temperature resistant, strong magnetic stirrers provide powerful stirring force, suitable for mixing viscous liquids.
Safety lock to prevent accidental changes in operating status.
Buzzer: When the machine malfunctions or the countdown for the timing function ends, the buzzer emits a "beep" sound to alert the user.
Residual heat warning: When the plate temperature exceeds 50°C, heating will be automatically turned off, and the display will show a flashing "HOT" warning. Even when the power is turned off, the "HOT" warning will continue flashing on the display, alerting the user of the high temperature.
Two independent safety circuits continuously monitor the device. In case of overheating, sensor malfunction, or a system error, the machine will stop heating. If a short circuit occurs, the power will be automatically cut off, ensuring the operator's safety.
DC brushless motor: Spark-free, long lifespan, low noise, maintenance-free, and smooth operation.
LCD display: Shows set and real-time values for speed, time, and temperature, offering clear and intuitive readings.
The timer function is available with a range of 1 minute to 99 hours and 59 minutes. Once the countdown ends, heating will stop, but stirring will continue to avoid thermal damage to the sample.
Remote control function is available, allowing the device to be connected to a computer.
Safety temperature can be set.
