Heated Magnetic Stirrer DMS5-340M (CAT#: STEM-BC-2424-ZJF)

The DMS5-340M is a heated magnetic stirrer designed for simultaneous heating and stirring of liquid samples in laboratory environments. It combines precise thermal management with consistent rotational mixing, making it suitable for synthesis, reaction monitoring, and sample preparation workflows. The unit features a chemical-resistant working surface, typically constructed from ceramic-coated aluminum or glass-ceramic material, providing durability against corrosive reagents. Speed is controlled via a brushless DC motor to deliver smooth, maintenance-free operation across the full speed range. Temperature is regulated through an embedded PID control algorithm, ensuring minimal deviation from the set point during extended operation. An external PT1000 temperature sensor port is provided for direct measurement of sample temperature rather than plate temperature, improving experimental accuracy. Safety features include an independent overheat protection circuit and a residual heat indicator that remains active even after the unit is powered off. The instrument is available in single-position and multi-position configurations to accommodate different throughput requirements. It is compatible with a range of stirring accessories and round-bottom or flat-bottom vessels of various capacities. This stirrer is suitable for general chemistry, pharmaceutical research, and quality control applications.
