Drawell Automatic Kjeldahl Analyzer with Distillation and Titration DW-K9860

Drawell Automatic Kjeldahl Analyzer with Distillation and Titration DW-K9860

Product overview

DW-K9860 Automatic Kjeldahl Analyzer is an automatic device integrating distillation and titration functions designed based on classic Kjeldahl nitrogen determination method . It’s equipped with the latest core control system, powerful automatic degree and high-quality components, can easily achieve automatic cleaning of digestion tubes and titration cups, control steam supply and have real-time detection of condensation temperature. High-accuracy charging pump and titration system ensure test results accuracy, and multiple fluid level detection gives a smooth test process.

The Drawell Automatic Kjeldahl Analyzer with Distillation and Titration DW-K9860 supports research, pharmaceutical, environmental, food, industrial, and quality-control laboratories. Scientific China provides model selection, configuration review, export coordination, and formal quotations.

Key features

• High accuracy dozing and working: adopt 4 KNF pumps work for dozing, measurement liquid volume.
• Easy Maintenance: Pre-install functions of cleaning, including receiving cup cleaning, alkali pipeline cleaning, boric acid pipeline cleaning, acid washing, and steam bottle evacuation. support customer to make the routine maintenance easily.
• High titration accuracy, up to 2.0μL/step.
• Integrated printer on the instruments.
• Automatic cleaning ensure operator safety and save time.
• External titration cup design gives operator real-time control of the whole test process.
• Steam flow is controllable, satisfying different test requirements.
• Regent barrel enjoys fluid absence warning function, ensuring smooth test going.
• High-precision charging pump and titration ensure test results accuracy.
• The temperature of distilled liquid is detected real time. If the temperature of distilled liquid is abnormal, to ensure the accuracy of experiment’s result, instrument will stop working.
• There is no automatic endpoint detection; judgment relies on color change of boric acid absorbing solution. Continue distilling for 5–10 minutes after the absorbing solution turns from purplish red to blue-green. Lift the condenser tube out of the liquid surface and distill for another 2 minutes to wash residual ammonia on the tube wall and avoid low results. Extend distillation time for samples high in protein and fat.
• Inconsistent manual addition of alkali solution in each test, leading to variable ammonia release;
• Unstable steam supply due to fluctuating heating flame;
• Large human visual error as the titration endpoint is judged by naked eyes;

Applications

• Food and Agricultural Product Testing
• Feed Industry Quality Control
• Agricultural and Environmental Monitoring
• Pharmaceutical and Chemical Research
