Fully Automatic Kjeldahl Nitrogen Analyzer Color method protein Analysis GB/T

Product Specification

ST-115CS Fully automatic Kjeldahl nitrogen analyzer

Name: Automatic Kjeldahl nitrogen analyzer

model: ST-115CS=ST115C+STZ-08C

ST-115CS Kjeldahl nitrogen determination method is a classic method for determining nitrogen. The Kjeldahl method is used to determine soil, food, animal husbandry, agricultural products, feed, and other nitrogen-containing compounds. When using this method to determine samples, three processes are required: sample digestion, distillation separation, and titration analysis

The ST-115CS fully automatic Kjeldahl nitrogen analyzer is a "nitrogen element" (protein) analysis system developed based on the classic Kjeldahl nitrogen analyzer method, using fully automatic distillation titration technology and color method to determine the endpoint. Its method and manufacturing comply with the manufacturing standards of "GB/T 33862-2017 Fully (Semi) Automatic Kjeldahl Nitrogen Analyzer" and relevant international standards

Product Features:

●The operating system adopts a 7-inch color touch screen, with easy human-machine dialogue operation and easy learning

●The three-level permission management, electronic records, electronic tags, and operation traceability query system meet the relevant certification requirements

●The system automatically shuts down after 60 minutes of unmanned operation, which is energy-saving, safe, and reassuring

● Choose R, G, B coaxial three color light sources and three color sensors, with a wide range of color adaptability and high accuracy

●Automatic adjustment of R, G, and B light intensity suitable for analyzing samples of different concentrations

●The three titration curves of R, G, and B can observe the changes in the sample during the titration process, providing assistance for analysis

●The titration cup is installed in an open manner, making it convenient for users to observe the titration process and clean the titration cup

●Imported linear motor and injection needle tube form a "plunger titration pump" with high control accuracy and stability

●The titration speed can be set arbitrarily from 0.05ml/second to 1.0m/s

●Distillation time can be freely set from 10 seconds to 9990S

●The instrument has a built-in protein coefficient query table for users to access, query, and participate in system calculations, making it convenient for users to use

●16M data storage capacity can store 1 million sample data for reference, 5.7CM automatic paper cutting thermal printer

●99 groups of users set up their own program (recipe) management system

● Measurement of "nitro" class samples through delay analysis

●The metal material (304 stainless steel) steam pot has stable, reliable, and pressure resistant performance

● Leakage protection system prevents leakage and electric shock to ensure the safety of operators

●The digestive system does not add reagents or heat to prevent injury from reagents or steam

●The safety door is not closed and the system does not work. The 5mm thick transparent safety door ensures personal safety

●Automatic shutdown and alarm of steam system water shortage system to prevent accidents from occurring

●Automatic shutdown and alarm of steam boiler overheating system
