DMS4-550 Glass Ceramic Digital Hotplate Stirrer with 550°C heating | DLAB Scientific

Product Description

The DLAB DMS4-550 LCD Glass Ceramic Heating Magnetic Stirrer with Timer is a high-performance, compact laboratory instrument engineered for highly precise mixing and high-temperature thermal control. It features a space-saving 4-inch square glass-ceramic work plate that delivers exceptional resistance against aggressive chemical splashes, strong acids, and alkalis, while ensuring rapid and highly uniform heat distribution across its entire surface. This makes it perfectly suited for chemical synthesis, pharmaceutical compounding, environmental analysis, material science research, and routine quality control (QC) workflows in industrial and clinical test environments.

Equipped with a highly reliable, spark-free brushless DC motor, the DMS4-550 operates smoothly and quietly without requiring regular maintenance. The system effectively manages up to 10 liters of water volume and generates a stable stirring speed range from 50 to 1500 rpm. A bright, high-contrast digital LCD interface allows real-time visualization of set and actual values for temperature, time, and stirring speed simultaneously. Operators can select from three advanced heating modes—Rapid (Mode A), Standard (Mode B), and Stable (Mode C)—to customize thermal rates to their specific sample sensitivities. The integrated digital timer runs from 1 minute up to 99 hours and 59 minutes. Crucially, when the timer countdown concludes, the machine cuts off the heating element automatically but continues to stir, preventing localized hot spots or thermal degradation of sensitive samples.

Safety is built deeply into the core architecture of this hotplate stirrer. The full-metal housing includes an integrated fluid drainage platform and a raised waterproof edge configuration to stop liquid ingress from damaging internal electronic components. A bright “HOT” residual heat warning flashes visibly on the display whenever the plate surface exceeds 50°C, and this alert remains active even if the main instrument power switch is turned off. Dual independent safety circuits continuously monitor operations, activating an automatic shutdown at 580°C to provide failsafe overheating protection. For ultra-precise sample environment management, users can attach an external PT1000 temperature sensor to bypass the baseplate readings and sample directly with a narrow control accuracy of ±0.2°C. Additionally, the unit incorporates a safety lock function to block accidental changes to working parameters during active runs, alongside an RS232 data connector that facilitates seamless PC integration and remote control.
