Product Details

9870 automatic Kjeldahl nitrogen analyzer is for automatic distillation/separation and analysis of "nitrogen" (protein) through external related technologies.

9870A is a fully automatic Kjeldahl nitrogen analyzer has automatic discharge of digestion waste liquid, and is equipped with a refrigeration system without consuming tap water.

9870B is a fully automatic Kjeldahl nitrogen analysis methods are titration technology and color method to determine the end point and related international standards. It has automatic discharge of digested waste liquid, equipped with refrigeration system without consuming tap water, and the operating system adopts dual system of computer and touch screen to switch freely......

Characteristics

The operating system adopts a 7-inch (10-inch for 9870A/9870B) color touch screen. The three-level user management meets the relevant certification requirements, and the operation traceability query system.

The system automatically shuts down after 60 minutes of unattended operation, saving energy, safety, and peace of mind. Choose R, G, B coaxial tricolor light source and tricolor sensor, with wide color adaptability and high precision. Measurement of "nitro"-like samples by time-lapse analysis.

Automatic adjustment of R, G, B light intensity for analysis samples of different concentrations. The three titration curves of R, G and B can observe the change of the sample during the titration process and provide help for the analysis. The steam boiler over-temperature system automatically shuts down and alarms.

Imported linear motor and injection needle form a "plunger titration pump", with high control accuracy and stability. The titration speed can be adjusted from 0.13ml/s---0.7m/6 files. Distillation time can be freely set from 60 seconds to 900S, 10 seconds per gear.

16M data storage capacity can store 100,000 sample data for reference, 5.7CM automatic paper cutting thermal printer. Metal material (304 stainless steel) steam boiler has stable performance, reliability and pressure resistance. The water shortage system of the steam system automatically shuts down and alarms to prevent accidents.

The leakage protection system prevents leakage and electric shock to ensure the safety of operators. Absence of digestive tube system does not add reagents or heat to prevent reagents and steam from hurting people. The system does not work if the safety door is not closed, and the 5mm thick transparent safety door ensures personal safety

The titration cup is clearly mounted, which is convenient for users to observe the titration process and clean the titration cup. The instrument has a built-in protein coefficient query table for users to access, query and participate in the system calculation, which is convenient for users to use.

Cooling water flow monitoring prevents insufficient water flow causing sample loss and affecting analysis results.(9870A/B). Shut down and automatically clean the alkali pipeline to prevent pipeline blockage and ensure the accuracy of liquid supply.(9870A/B)

Sample over-temperature alarm and shutdown to prevent sample temperature rise and affect analysis data.(9870A/B). Automatic discharge of digestive waste liquid reduces labor intensity of staff.(9870A/B).

Automatic upload of sample weighing data, reducing tedious manual input one by one and input errors.(9870A/B). The internal standard of the titrant concentration eliminates the systematic error of the difference between the human and the instrument, with high precision and convenience.(9870A/B)

The steam flow can be adjusted arbitrarily from 40%--100% to suit different concentrations of samples.(9870A/B). Titration-while-distillation mode saves analysis time and reduces ineffective distillation power consumption. (9870A/B). Steam overpressure alarm and shutdown to prevent accidents.(9870A/B)

①The computer operation and the host touch screen operation can switch between dual modes at will; ②Analysis results query and export; ③Analysis results can automatically generate analysis reports, print and export.(9870B). The computer operating system developed based on Windows7 is the same, which is convenient for application.(9870B)
