KDN Series Semi-automatic Protein Analyzer
Protein analyzer is also called crude protein analyzer, KjeldahI nitrogen analyzer, is a set of automatic intelligent protein detection instrument designed according to the classic Kjeldahl nitrogen determination principle, widely used in the detection of grain, oil, food, dairy products, beverages, feed, soil. The overall contact of ammonia nitrogen and protein nitrogen in fertilizers, sediments and chemical products is an important physical and chemical analysis instrument for product quality testing.
Product Advantages.
★ KDN Series protein analyzer adopts microcomputer for processing control.
★ Automatic distillation control, auto water addition, automatic water level control, and automatic water stop.
★ Various safety protections: digestive tube safety door device, steam generator water shortage alarm, water level detection failure alarm.
★ The shell of the crude protein analyzer is made of special plastic-sprayed steel plate, and the working area is made of ABS anti-corrosion panel, which is resistant to chemical reagent corrosion and mechanical damage to the surface, and is resistant to acid and alkali.
★ Water level detection, low water level alarm, instrument control system failure can automatically cut off the power.
★ The instrument adopts tap water source, which has wide adaptability and low requirements for experiments.
★ The instrument is composed of digestion furnace (different types for selecting) and azotometer distillatory.
★ The digestion furnace (numeric display model) is controlled by temperature control meter. It adopts infrared radiation heating. Insert the sample into the heating furnace to get the best heating effect.
★ Through the drainpipe and the air-bleed three-way, poisonous gases (e.g. SO2) emitted from the digestion tube could be taken to the cloaca by water (the gases could also be recycled by vacuum pump and recycle bottle) which could control the emitting of poisonous gases and save the installation of ventilated case. Samples could be digested thoroughly in about 40-90 minutes (according to the amount of nitrogen).
