Infitek Kjeldahl Digestion System, KJD-T4E, KJD-T8E, KJD-T20E

Infitek KJD-T Series Kjeldahl Digestion Systems

The Infitek KJD-T Series (KJD-T4E, KJD-T8E, KJD-T20E) provides a range of high-performance electric heating digestion solutions tailored for different laboratory throughput requirements. Utilizing advanced infrared heating technology and high-quality furnace materials, these systems are designed to provide rapid, uniform mineralization for the determination of nitrogen and protein content in various samples.

Series Overview & Throughput Options

The KJD-T Series is categorized by sample capacity to fit any laboratory scale:

• KJD-T4E: 4-position system for small-scale testing or R&D applications.

• KJD-T8E: 8-position system for mid-range throughput in quality control labs.

• KJD-T20E: 20-position system for high-volume commercial and industrial testing.

Key Performance Features

• Infrared Radiation Heating: These units utilize high-efficiency infrared heating elements, which offer faster ramp-up times and lower thermal inertia compared to traditional heating methods.

• Superior Thermal Uniformity: The furnace design ensures minimal temperature variance between sample positions, guaranteeing that all tubes in the batch undergo an identical digestion process.

• High-Quality Ceramic Construction: The heating chamber is constructed with specialized ceramic and insulation materials that maximize heat retention and energy efficiency while protecting the internal electronics.

• Corrosion-Resistant Exterior: The chassis is finished with a multi-layer anti-corrosive coating, providing long-term protection against the acidic environment typical of sulfuric acid digestion.

• Independent Heating Control: Designed for stability, the electrical architecture ensures consistent power delivery to each heating position throughout the entire digestion cycle.

Safety and Operational Design

• Integrated Exhaust Management: These systems are designed for seamless integration with the KJD-WGH series collection hoods and KJD-SCB neutralization scrubbers, ensuring 100% of corrosive fumes are captured.

• Individual Tube Protection: The support rack is engineered to hold standard 300ml digestion tubes securely, preventing vibration or accidental breakage during the boiling phase.

• User-Centric Controls: Featuring a clear digital interface, the systems allow operators to monitor and adjust temperatures precisely to meet standardized testing protocols (AOAC, ISO, etc.).

• Safety Overheat Protection: Includes built-in safety mechanisms that monitor thermal levels to prevent overheating, ensuring laboratory and operator safety.
