KDN-390F Automated distillation unit
KDN390F automatic Kjeldahl nitrogen analyzer is a distillation device for automatic nitrogen determination of samples designed according to the classical Kjeldahl method. The instrument is easy to install and operate. The measurement is accurate, the use is safe, reliable, timesaving and laborsaving; 7inch color screen operation, onebutton start design, high degree of automation. It is widely used in the analysis and determination of crude protein in grain, food, feed, soil, fertilizer, water, sediment, chemicals, dairy products, brewing, sugar refining, medicine, coal, rubber and other substances. It is an ideal tool for laboratory operators.
KDN390F automatic Kjeldahl nitrogen analyzer can also be used for other types of distillation, such as the analysis of sulfur/cyanogen/phenol, and can also be used for direct distillation of nitrogen.
Product features:
l The body is made of engineering ABS plastic, which is beautiful, corrosionresistant and never rusty.
l The imported chip integrated circuit control system is adopted to ensure the high quality and high standard of the instrument
l New operating system, 7inch highdefinition touch color screen, userfriendly design, simple and easy to understand procedures, so that experimental operators can easily master
l Fully automatic water replenishment, water addition, alkali addition, acid addition and distillation functions are completed by one key, providing safe and convenient operation.
l Automatically memorize the last parameter setting, which is convenient for operation and can be flexibly adjusted according to the detection requirements.
l Set start, pause and emergency stop functions, and flexibly control the experiment process to prevent emergencies.
l Working mode: hand in hand. Onebutton start in automatic mode; In manual mode, all functions can be started at the same time or separately without mutual interference.
l Receiving bottle bracket lifting system, before use or the last minute will automatically judge the program, automatic lifting, gentle movement process, safe and reliable, more in line with the national standard operation requirements, to ensure accurate test results.
l Each program has the functions of fault alarm prompt and automatic stop alarm after distillation, which improves the safety and convenience of the instrument.
l Double protection procedures of water shortage and overtemperature of the steam generator are adopted to prevent dry burning due to water shortage, and a highsensitivity probe is adopted to stably control the required distilled water capacity and improve the use safety factor.
l Alkali supplement switch shall be designed within one minute after the start of distillation to prevent the sample from being scrapped due to too little alkali added to some samples.
l The splashproof tube is made of highperformance acidresistant and alkaliresistant materials at one time, which ensures the air tightness of the experiment, is not easy to age and prolongs the service life.
l The easy-pull glass safety door is simple and practical, and improves the use safety
l Water-saving function design, advocating the concept of green environmental protection
