（China）YY8900 Automatic Kjeldahl nitrogen analyzer

Short Description:

Summary:

Kjeldahl method is a classical method for nitrogen determination. Kjeldahl method is widely used

to determine nitrogen compounds in soil, food, animal husbandry, agricultural products, feed and

other products. The sample determination by this method requires three processes: sample

digestion, distillation separation and titration analysis

The company is one of the founding units of the national standard of “GB/T 33862-2017 full

(semi-) automatic Kjeldahl nitrogen analyzer”, so the products developed and produced by

Kjeldahl nitrogen analyzer meet the “GB” standard and related international standards

8900 Kjelter nitrogen analyzer is currently the domestic sample placing the largest amount (40),

the highest degree of automation (no need to manually transfer test tubes), the most complete supporting equipment products (optional 40-hole cooking furnace, 40 tube automatic washing

machine), choose the elite company’s series of products to solve the “sample one furnace cooking,

no one to adhere to automatic analysis, The complicated work such as automatic cleaning and

drying of test tubes after analysis saves labor cost and improves work efficiency.
