Globe Scientific GHS-550 Series Magnetic Stirrer Hotplates for Precise Laboratory Heating and Mixing
Product Description
The Globe Scientific GHS-550 series comprises versatile magnetic stirrer hotplates engineered for precise temperature control and effective mixing in biotechnology and chemical laboratories. Designed with a compact footprint and a durable 7-inch glass ceramic surface, these benchtop units support temperature ranges from ambient +5°C up to 550°C, powered by a robust 1000-watt heater.
Key features include:
- Microprocessor-controlled PID heating with ±0.2°C accuracy (optional PT1000 sensor for in-vessel temperature measurement)
- LCD or LED display options for intuitive temperature and stirring speed control
- Maintenance-free brushless DC motor delivering strong magnetic coupling capable of stirring volumes up to 20 liters (GHS-550HSP) or 10 liters (other models)
- Analog and digital control knobs for flexible speed adjustment ranging from 0 to 1500 rpm
- RS232 communication port on GHS-550HSP model for remote monitoring and data transmission (software not included)
- Overtemperature protection with automatic shutoff at 580°C and visual “hot” warning above 50°C
- Chemical-resistant glass ceramic top plate for easy cleaning and durability under intense bioprocessing conditions
These hotplate stirrers are critical tools in molecular diagnostics, bioprocessing workflows, and synthetic biology research, providing consistent solution homogeneity and reliable heating profiles. Their precise temperature control and powerful stirring capability make them widely used in biomedical engineering, cell imaging experiments, and biomanufacturing pipelines requiring stringent reaction conditions and reproducible mixing.
The GHS-550 range supports dual voltage inputs (100-120V 60Hz or 200-240V 50Hz) and is suitable for laboratory environments with up to 80% relative humidity (non-condensing). Its compact dimensions (215x360x108 mm) and moderate weight (3.8 to 5.3 kg depending on model) help conserve valuable bench space in research labs focused on gene editing and molecular cloning workflows.
In summary, the Globe Scientific GHS-550 magnetic stirrer hotplates provide precise thermal management combined with high-efficiency stirring, making them essential for advanced biotechnology laboratories requiring accurate temperature control and thorough mixing of biological and chemical samples.
