RS232 Data Interface

The LCD Digital Heating Magnetic Stirrer (DMS5-340) is a high-performance, programmable benchtop instrument engineered for reliable, precise, and safe simultaneous heating and stirring in clinical diagnostics, pharmaceutical quality control, analytical chemistry, trace element analysis, and life science research. Combining a maximum stirring capacity of 20 liters with a powerful heating capability up to 340°C on a 5-inch (Ø135 mm) ceramic-coated aluminum work plate, the LCD Digital Heating Magnetic Stirrer (DMS5-340) is the ideal choice for demanding laboratory applications including sample digestion with strong acids for trace metal analysis, culture media preparation, and chemical synthesis.

Every LCD Digital Heating Magnetic Stirrer (DMS5-340) is equipped with a high-resolution LCD display that simultaneously shows the set and actual values for both temperature and speed, a maintenance-free spark-free brushless DC motor, and a PID temperature controller for stable, precise heating. The ceramic-coated aluminum work plate provides exceptional chemical resistance against strong acids and alkalis, ensuring long-term durability even with aggressive reagents such as nitric acid for trace metal digestion. With an integrated PT1000 external temperature sensor port (±0.2°C accuracy), users can accurately control sample temperature, making it suitable for temperature-sensitive assays and enzyme kinetics.

Key user-focused features include three selectable heating modes—fast heating (A), standard heating (B), and stable heating (C)—allowing users to choose the optimal thermal profile for their specific application. The programmable timer, ranging from 1 minute to 99 hours 59 minutes, enables unattended operation with automatic shutdown upon completion (heating stops, stirring continues to prevent sample degradation) and an audible buzzer alert. The powerful parallel magnetic field provides uniform stirring at any position on the plate, making the DMS5-340 ideal for parallel reactions in synthetic biology and molecular diagnostics workflows. Safety is paramount with dual independent safety circuits providing redundant over-temperature protection, an independent residual heat warning indicator ("HOT" flashes at >50°C and continues even after the unit is turned off), a safety lock to prevent accidental setting changes, adjustable safety temperature (50–420°C), and IP42 protection class for dust and water resistance. The RS232 data interface enables remote PC control and data logging for full experiment documentation.

For the clinical laboratory scientist, trace element analysis technologist, and pharmaceutical quality control analyst, the LCD Digital Heating Magnetic Stirrer (DMS5-340) delivers the programmable, precise, and safe heating and stirring required for clinical chemistry sample digestion, trace metal analysis sample preparation (blood lead, urine cadmium, heavy metals), culture media preparation, enzyme activity assays, and drug dissolution testing. For the patient, the reliable performance of this instrument ensures that diagnostic tests and pharmaceutical products are accurate and reproducible, directly supporting effective clinical decision-making, appropriate treatment selection, and patient safety.
