× Equipment corrosion and sample contamination:
Frequent use of strong corrosive reagents like concentrated nitric acid, aqua regia, and hydrofluoric acid for digestion easily corrodes the heating plate surface. The resulting rust contaminants pollute samples, leading to deviations in analysis results.
× Inaccurate temperature control and failed digestion:
Digestion temperature is key to ensuring complete sample decomposition. If the displayed temperature does not match the actual plate surface temperature, it can lead to incomplete digestion or excessive acid evaporation, directly impacting the accuracy and precision of the analysis.
× Low efficiency for batch processing:
Uneven plate surface temperature forces lab personnel to constantly reposition sample vessels to ensure consistency. This is not only time-consuming and labor-intensive but also makes it difficult to guarantee uniformity across samples in the same batch.
The SD series Intelligent Electric Hotplate tackles the core challenges of element analysis pretreatment, delivering superior performance to ensure efficient and safe digestion processes while safeguarding data authenticity and reliability.
√ Excellent corrosion resistance:
Core advantages: The surface is made of silicon carbide, and the body is constructed with ABS plastic, which can withstand corrosion from various strong acids and alkalis, including hydrofluoric acid.
Value for You: Completely eliminates sample contamination caused by equipment corrosion, ensuring your elemental analysis data is authentic and reliable. For cleaning, you can directly use a steel brush dipped in dilute acid, making maintenance simple.
√ Unique plate surface temperature measurement and precise PID temperature control ensure optimal digestion performance:
Core advantage: The thermocouple directly monitors the actual surface temperature,not the heating element temperature, and the displayed temperature is the closest to the sample solution temperature.
Value for You: Precisely controls the temperature for every digestion process, ensuring complete sample decomposition, fundamentally improving the accuracy and repeatability of analysis results.
√ Excellent temperature uniformity, freeing manpower and improving efficiency:
Core advantage: The temperature difference at each point on the plate surface does not exceed ±2℃.
Value for You: Uniform temperature ensures consistent digestion results for samples in the same batch. Lab personnel no longer need to frequently monitor and move samples, enabling simultaneous operation of multiple devices and significantly improving pre-treatment efficiency.
√ Safe and reliable, durable:
