AELAB Kjeldahl Digester SH420F Series – High-Precision Infrared Heating

Anti-corrosion design: TEFLON coating on the surface, acid/alkali proof.
Heating uniform and fast: Adopt graphite block(antioxidant), heating faster and energy transfer faster, temperature between holes more uniform.
Safety protection: adopt unique air duct insulation tech, keep the temperature ultra low, protect operator
SH420F Kjeldahl Digestion ststem adopts globally advanced high-temperature infrared t radiation heating technology and microprocessor control platform, boasts accurate temperature control and quick temperature rise. It has two kinds of temperature rise mode: linear and curve temperature rise mode, and offers 20 digestion programs for control of temperature rise curves.
neutralization system has many functions such as triple filtration, condensate recovery of exhaust gas, filtration and neutralization device. The product adopts high-quality Anticorrosive Pumps, low noise, strong suction, reduce exhaust emissions,eco-friendly.

🔬 How It Works?

The SH420F Kjeldahl Digester uses infrared heating combined with graphite block conduction to rapidly and evenly heat digestion tubes up to 450 °C. A microprocessor control platform regulates temperature with ±1 °C accuracy, offering both linear and curve ramping modes for different digestion protocols. Exhaust gases are safely managed through a triple filtration and neutralization system, ensuring minimal environmental impact.
