SH420F/SH220FKjeldahl Digester
Kjeldahl Apparatus is used to determine organic nitrogen (n2) and protein contents in chemical substance. This estimation is done by Kjeldahl digestion method. These units are widely used in food, environmental, urea and chemical industries.
SH420F
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.
Hanon 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.
SH220F
Graphite block, Compare metal heating, the heating is more uniform;
Corrosion resistant design, PTEF coating is very useful when strong acid experiments;
PID temperature control, to achieve 450℃ only need 25 minutes.
4.3 inch color screen, display real running situation;
Multi protection, such as Over-current protection, High temperature warning Overload protection Gas collection hood system with suction pump (Suction Cap)
Special air insulation design, when heating solution, liquid need backflow, we design special air flue to keep the whole tube near uniform temp
