Description
The MS-H340-S4 LCD 4-Channel Digital Magnetic Hotplate Stirrer combines powerful magnetic stirring and accurate heating for multi-sample processing in research, chemistry, and bio-pharmaceutical labs. Each of the four channels operates independently, allowing customized temperature and stirring control with real-time feedback on the LCD display. A built-in PID controller ensures stable and precise heating up to 340 ?C, while a brushless DC motor delivers quiet, reliable, and maintenance-free stirring. An external PT1000 temperature sensor enhances measurement accuracy, and the ceramic-coated stainless steel work plates offer excellent chemical resistance. Safety features include high-temperature protection up to 420 ?C, making this stirrer suitable for demanding laboratory workflows.
