Globe Scientific GHS-550 Series Hotplates and Magnetic Stirrers with PID Control and Brushless DC Motor

The *Globe Scientific GHS-550 series* encompasses a range of laboratory hotplates and magnetic stirrers, designed specifically for precise heating and mixing in biotechnology, molecular diagnostics, and bioprocessing workflows. These benchtop devices feature a durable 7-inch chemical-resistant glass ceramic surface enabling easy cleanup and long-term stability in demanding laboratory environments.

Key technical specifications:

• Heating Power: Powerful 1000W heater capable of reaching temperatures up to 550°C with overtemperature protection at 580°C, ensuring safety during thermal-sensitive applications.
• Temperature Control: Microprocessor-controlled with PID temperature regulation (GHS-550HSP model), offering temperature accuracy within ±1°C below 100°C and ±1% above 100°C, critical for reproducible experimental conditions in molecular biology and synthetic biology research.
• Stirring Capability: Equipped with a maintenance-free brushless DC motor delivering strong magnetic coupling, enabling stirring volumes up to 20 liters (GHS-550HSP) and stirring speeds ranging from 0 to 1500 rpm, suitable for homogenizing large sample volumes in biomanufacturing and cell culture preparation.
• Display and Interface: Varied display options including LED and LCD, with models like GHS-550HSP offering an LCD for enhanced monitoring of speed and temperature. The inclusion of an RS232 communication port facilitates integration with PC-based data acquisition systems for remote control and data logging, supporting rigorous documentation standards in clinical diagnostics.
• Design: Compact footprint (215x360x108 mm) conserves valuable benchtop space; chemical-resistant glass ceramic surface ensures durability and compatibility with a range of chemical reagents.
• Safety Features: Integrated “hot” warning indicator above 50°C and secure overheating cut-off enhance operator safety during extended bioprocessing runs.

These hotplates and stirrers are widely used in biomedical engineering, live-cell imaging sample preparation, and fluorescence analysis protocols, proving essential for molecular cloning workflows, synthetic biology research, and biopharmaceutical production pipelines. Optional accessories such as a PT1000 external temperature sensor and retort stand enable direct temperature measurement inside reaction vessels, improving thermal uniformity assessment.

The Globe Scientific GHS-550 series offers a technically robust solution combining precision temperature control, scalable stirring capacity, and automated data integration, making it a preferred choice for scientists and researchers focused on biotechnology and clinical laboratory applications.
