KDN-19A Volatile Base Nitrogen Analyzer, Shanghai XianJian Instrument Co., Ltd. (CAT#: STEM-AIAE-3356-LGZ)

Volatile base nitrogen is an important indicator of food freshness grade in meat, fish and eggs, and it is also an important indicator for detecting the fermentation status of raw materials during fungus culture. Compared with the semi-micro nitrogen determination method commonly used in the national standard, the automatic Kjeldahl method has a very simple distillation and nitrogen determination process, which can avoid repeated cleaning of the reaction tank. Our company's KDN-19A type is specially designed for the detection of volatile base nitrogen, which is more in line with the experimental requirements, so as to avoid performance waste. One sample takes about 5 minutes, and it is suitable for the determination of large batches of samples. The results have high precision, good accuracy, high recovery rate and simple method.

Microcomputer chip control, digital display of distillation time, and countdown function, more intuitive and clear.
Add a double protection program for water shortage in the evaporation furnace to prevent dry burning due to water shortage and improve the safety factor.
Increase the overpressure and pressure relief protection of the evaporation furnace to prevent the explosion of the bottle caused by the excessive pressure of the evaporation furnace caused by the failure of the solenoid valve, and improve the safety factor of use.
The internal components of the instrument are fully upgraded, the work efficiency is increased by 25% compared with the previous generation, and the service life is longer.
In order to remove the receiving bottle one minute earlier, a new receiving bottle bracket is added, which is neat and orderly, enhances the customer's use experience, and is closer to the national standard operation.
Detection end alarm reminder.
Water-saving function design, through program control, condensed water is turned on synchronously when the sample is detected, and it is automatically turned off after the detection, advocating a new concept of energy saving, emission reduction and environmental protection.
The film touch button, feel comfortable, the panel is simple and refreshing.
Automatically memorize the last set data, suitable for different requirements of distillation.
The splash-proof pipe is formed of special high-performance acid and alkali-resistant heat-resistant plastic, which has good sealing performance and prolongs the service life.
Prevent the sucking function of the receiving and digestive juices to ensure the quality of the test and the safety of use.
