Description
The DMS5?340 LCD Heating Magnetic Stirrer with Timer is a robust and versatile laboratory device designed for efficient mixing and precise thermal control of liquid samples. It features a brushless DC motor for quiet, maintenance?free operation and supports stirring speeds from approximately 50?to?1500?rpm to handle both simple and viscous solutions. A high?resolution LCD panel displays actual and set values for speed, temperature, and remaining time, while the programmable timer offers a wide range from 1?minute up to 99?hours and 59?minutes. The unit?s ceramic?coated glass?ceramic work surface is highly resistant to corrosion and easy to clean, and built?in safety circuits provide overheat protection and residual heat warnings. With a maximum heating range up to 340??C and compatibility with external temperature sensors, the stirrer delivers reliable performance for professional research, educational, and industrial laboratory environments.
