Product Info
Infitek KJD-420F Kjeldahl Graphite Digester
The Infitek KJD-420F is a high-performance graphite digestion system designed for the efficient preparation of samples for Kjeldahl nitrogen analysis. Utilizing advanced global heating technology, the KJD-420F provides superior thermal uniformity and rapid heating, making it an essential tool for laboratories requiring high-precision sample mineralisation in food, feed, and environmental testing.
Key Performance Features
-
Graphite Block Heating: The high-purity graphite heating block ensures exceptional thermal conductivity and a minimized temperature gradient between sample positions (≤ 1.5°C), leading to highly consistent digestion results.
-
Advanced Temperature Control: Equipped with a precision PID control system, the KJD-420F offers a wide temperature range (Ambient to 450°C) with high accuracy, allowing for the processing of even the most demanding organic and inorganic samples.
-
Multi-Step Programmable Digestion: The intuitive controller allows users to program and save multiple heating stages, enabling automated transitions through different temperature ramps and hold times to optimize the digestion cycle.
-
Corrosion-Resistant Architecture: The external housing is treated with a specialized anti-corrosive coating, while the internal components are designed to withstand the harsh acidic environment typical of sulfuric acid digestion.
-
Rapid Thermal Response: The high-efficiency heating elements allow for quick ramp-up times, significantly reducing the total preparation time and increasing overall laboratory throughput.
Safety and Durability
-
Over-Temperature Protection: The system includes an independent safety circuit that automatically cuts power if the temperature exceeds the set safety limit, protecting both the operator and the samples.
-
Intelligent Waste Gas Management: Designed for seamless integration with the KJD-WGH collection hood, the system ensures that all corrosive fumes are safely contained and directed toward a neutralization unit.
-
Stable Structural Design: The robust construction ensures long-term stability under continuous high-temperature operation, maintaining consistent performance even in high-volume testing facilities.
