The laboratory hotplate GHS-550H from Globe Scientific delivers high-temperature performance up to 550°C with a 1000-watt heater and 7×7 inch glass ceramic working surface. This digital hotplate combines precise temperature control with chemical-resistant construction for demanding laboratory heating applications.
Laboratory Hotplate GHS-550H Features
A glass ceramic plate provides outstanding chemical resistance and even heat distribution across the generous 7×7 inch surface. The LED display and control knobs connect to a microprocessor for stable temperature regulation. A hot warning LED illuminates when the plate exceeds 50°C to protect operators from accidental burns.
Overtemperature protection at 580°C safeguards equipment during high-temperature runs. Optional PT1000 sensor and retort stand deliver closed-loop temperature control within ±0.2°C for exacting protocols.

High-Temperature Hotplate Applications
Analytical laboratories use this hotplate for acid digestions, high-temperature evaporations, and sample ashing that exceed the capability of standard 380°C units. Materials science labs rely on the 550°C range for thermal treatment and sintering preparation work.
The larger 7×7 inch surface accommodates bigger flasks and beakers that smaller hotplates cannot support. Research and QC labs benefit from the consistent heat output of the 1000W element.
Why Choose Globe Scientific Hotplates
Globe Scientific hotplates and stirrers are engineered for laboratory professionals who need dependable daily performance. Each unit undergoes quality testing before shipment, and the microprocessor-controlled circuits maintain accuracy across thousands of heating cycles. The ceramic and glass ceramic surfaces resist common laboratory solvents including acetone, ethanol, methanol, and dilute acids.
Compared to consumer-grade heating equipment, these laboratory-rated hotplates include safety certifications, overtemperature protection, and optional sensor feedback that industrial and academic labs require for compliance and sample protection.

Frequently Asked Questions
What is the difference between GHS-550HS and GHS-550HSP hotplate stirrers?
The GHS-550HSP upgrades to an LCD display, built-in PID temperature control, 20L stirring capacity, and an RS232 port for PC data logging. The GHS-550HS uses an LED display and stirs up to 10 liters.
Can I connect the GHS-550HSP to a computer for data logging?
Yes. The GHS-550HSP includes an RS232 serial port for remote PC communication, control, and temperature data transmission. Software is sold separately from the instrument manufacturer.
What plate size and maximum temperature does the GHS-550 series offer?
The GHS-550 series features a 7×7 inch glass ceramic plate rated to 550°C with a 1000W heater. A hot warning LED illuminates when plate temperature exceeds 50°C for operator safety.
