This kjeldahl apparatus is highly reliable and features a unique alkaline pump anti-crystallisation technology that eliminates alkaline pump crystallisation problems.
KA-520 automatic kjeldahl apparatus adopts an advanced 16-bit triple-base chromaticity color sensor. KA-520 also introduces self-developed alkali pump anti-crystallization technology, which successfully solves the problem of crystallization of the alkali pump and significantly improves the reliability and stability of the instrument.
The modular structure design of the kjeldahl apparatus ensures stability and reliability during use, as well as the accuracy of test results. This makes the KA-520 automatic kjeldahl apparatus a state-of-the-art instrument with excellent performance and reliable operation in nitrogen determination.
Automatic Kjeldahl Apparatus Feature:
Automated Operation
Automatically completes acid addition, base addition, water addition, and distillation.
Sample explosion-proof boiling
The methods of sample dilution and alkali addition can be set arbitrarily according to the different samples of users, so as to prevent the sample from bursting and boiling and improve the measurement accuracy.
Alkali pump anti crystallization.
The self-developed alkali pump anti crystallization technology solves the problem of alkali pump crystallization and improves the reliability of the instrument.
Steam adjustable
Steam pre adding mode, steam flow rate (1-100%) can be adjusted automatically, so as to achieve better distillation effect and ensure the accuracy of the experiment.
Security protection
Multiple intelligent protections, such as digestive tube in place detection, safety valve, condensate detection, steam generator overheating, overpressure protection, liquid level detection, etc., ensure the instrument and operator Staff safety.

FAQ
Principle of the Automatic Kjeldahl Apparatus
After heating, the sample is digested with concentrated sulfuric acid in the presence of a catalyst. The organic nitrogen in the sample is converted into ammonium sulfate. The Kjeldahl apparatus then calculates the nitrogen content in the sample based on the amount of base or acid consumed during the titration process.
Do you offer installation and training?
Yes, we provide comprehensive installation and training support to ensure smooth setup and efficient operation of the equipment.
