Product Description
The Hanon K9840 Automatic Kjeldahl Distillation Unit determines nitrogen and crude protein content across food processing, agricultural research, education, and industrial quality control laboratories in Bangladesh. Manufactured strictly by Hanon Instruments, this benchtop analyzer automates sample distillation to maximize analytical precision and laboratory productivity.
The instrument processes solid samples up to 6g or liquid samples up to 16mL per test, completing each distillation cycle within 3 to 6 minutes. An integrated 4.3-inch color LCD screen displays clear operational steps and real-time system status. Operators switch freely between manual and automatic modes to customize reagent addition for NaOH, acid, and distillation water according to specific testing requirements.
To guarantee operational safety and analytical consistency, the unit features built-in calibration functions for dilution water, alkali solution, boric acid solution, and washing flow. The system monitors the safety door, digestion tube presence, and cooling water flow in real time while offering automatic fault detection, emergency stop protection, and audible alarms. Furthermore, the automated alkali pipeline washing system and control system cleaning prevent cross-contamination and maintain high measurement accuracy over time. With dimensions measuring 400 x 385 x 735 mm and a net weight of 30 kg, this distillation unit integrates directly into professional laboratory workflows.

Price Range: In Bangladesh (BD), the regular market price for the Hanon K9840 Automatic Kjeldahl Distillation Unit typically ranges between BDT 390,000 and BDT 460,000, depending on import duties, shipping, and local supplier support packages.
Procurement Procedure: For official corporate price quotations, institutional tenders, and direct stock verification in BD, contact authorized laboratory distributors such as Federal Scientific Mart (fsm.com.bd).
Q3: What warranty coverage and technical support are provided in Bangladesh?
Warranty Terms: The Hanon K9840 comes standard with a 12-month (1-year) factory warranty covering electronic display failures, internal pump defects, and heating steam generator faults.
Local Support: Authorized local suppliers like Federal Scientific Mart provide local technical guidance, installation support, spare reagent tubing, alkali and acid pump maintenance, and troubleshooting assistance across Bangladesh.
Q4: How do the automated reagent addition and cleaning functions operate?
Automatic Reagent Dosing: The unit automatically and accurately distributes sodium hydroxide, dilution water, and boric acid solutions according to programmed parameters.
Automated Cleaning: Features automatic cleaning of the control system and distiller piping, plus an automatic alkali pipeline washing function to prevent crystallization clogging and ensure measurement accuracy.
Q5: Which primary applications and industries utilize the K9840 Distillation Unit?
Food & Agriculture: Determining nitrogen and protein content in grains, food products, dairy, and animal feed.
