Infitek Waste Gas Collection Hood, KJD-WGH

Infitek KJD-WGH Waste Gas Collection Hood

The Infitek KJD-WGH series represents a critical safety interface for modern laboratories, specifically engineered to capture and contain hazardous acidic vapors during the chemical digestion process. This collection hood is an essential accessory for Kjeldahl nitrogen determination and other high-temperature wet digestion methods, ensuring that corrosive gases—such as sulfur dioxide (SO2)—are efficiently diverted into a neutralization system before they can compromise the laboratory environment.

Key Performance Features

• Exceptional Corrosion Resistance: Manufactured from high-grade, chemically inert materials (PTFE/High-density polymers), the KJD-WGH is designed to withstand continuous exposure to concentrated sulfuric acid and alkali fumes without structural degradation.

• Precision Hermetic Sealing: Equipped with high-performance fluorine rubber seals, the hood creates a robust, airtight connection with the digestion tubes. This specialized sealing technology maintains vacuum integrity and prevents hazardous leaks during the boiling phase.

• Uniform Suction Architecture: The internal manifold is aerodynamically optimized to provide balanced negative pressure across all sample positions. This ensures that fumes from every tube are captured with equal velocity, eliminating the risk of stray emissions.

• Thermal Stability: Engineered for high-temperature environments, the hood maintains its shape and sealing properties even when positioned directly above digestion blocks operating at temperatures up to 450°C.

• Versatile Compatibility: The KJD-WGH series is available in multiple configurations (including 6, 8, 12, and 20-position models) to integrate seamlessly with various digestion block capacities.

Operational Benefits

• Infrastructure Preservation: By containing corrosive gases at the source, the hood prevents the accelerated oxidation of fume hoods, laboratory furniture, and sensitive electronic instrumentation.

• Operator Health and Safety: It provides a vital layer of protection for laboratory personnel, significantly reducing the risk of respiratory irritation and chemical exposure.

• Simplified Maintenance: The modular, non-porous design allows for rapid disassembly and easy rinsing, ensuring that chemical residues do not accumulate and impact suction efficiency.

• Easy System Integration: Standardized connection ports allow for quick installation with the Infitek KJD-SCB-A neutralization scrubber or other specialized laboratory vacuum systems.
