0.2μL/Step Automatic Kjeldahl Analyzer Plunger Titration Pump 0.1—240mgN GB/T

Product Specification

ST115C Automatic kjeldahl analyzer

Kjetliner's method is a classical method for determining nitrogen. Kjetliner's method is used to determine soil, food, animal husbandry, agricultural products, fodder and other nitrogen compounds. When using this method to determine samples, three processes are required: sample dissolution, distillation and separation, and quantitative analysis

ST-115C automatic Kjetliner is an analysis system of "nitrogen element" (protein), which is developed based on the classic Kjetliner method, and the end point is determined by color method. Its method and manufacturing conform to the manufacturing standard of GB/T 33862-2017 Full (Semi) Automatic Kjetliner Method and international relevant standards.

Product features

● The operating system adopts 7 inch color touch screen, which makes man-machine conversation easy to operate and learn

● Three level authority management, electronic record, electronic label and operation traceability inquiry system meet relevant certification requirements

● Automatic shutdown of the system after 60 minutes of unmanned operation, energy saving, safety and security

● Select R, G, B three color light source and three color sensor, with wide color range and high accuracy

● Automatic adjustment of R, G and B light intensity is applicable to analysis samples of different concentrations

● Three curves of R, G and B can be used to observe the sample change in the process of determination and provide help for analysis

● Open installation of the measuring cup is convenient for users to observe the measuring process and cleaning of the measuring cup

● Imported linear motor and injection needle tube form a "ram type Titration Pump" with high control precision and stability

● Titration rate from 0.05 ml/S-1.0m/S at any setting

● Free setting of the distilling time from 10S-9990S

● The instrument has a built in protein coefficient query table for users to consult, query and participate in the system calculation for convenience

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

● Program (formula) management system set by 99 groups of users

● "NITROL" type samples can be measured by delayed analysis

● Metal material (304 stainless steel) Steam pot has stable performance, reliability and compressive capacity

● Electric leakage protection system to prevent electricity leakage and electric shock and ensure the safety of operators

● The alimentary canal absence system does not add reagents or heat to prevent injuries caused by reagents and steam

● Safety door is not closed, system does not work, 5mm thick transparent safety door ensures personal safety

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

● Automatic shutdown and alarm of steam boiler over temperature system.

All-round security protection system:

● Leakage protection: when there is leakage or the operator accidentally electric shock, the system will cut off the power supply to stop power supply, to ensure the safety of the operator;

● The interval type of adding alkali - the process of adding alkali is not an instant, but the interval type of adding, can appropriately reduce the acid, alkali too strong reaction.

● Elimination tube vacancy protection -- the system does not work when the elimination tube is not put in.

● Safety door absence protection -- when the safety door is not pulled down, the system does not heat, to ensure the safety of the distillation process operators.

● Overtemperature and overpressure protection of the steam system -- to prevent the danger caused by excessively high pressure of the steam system.

● Steam cylinder automatic water replenishment function -- when the steam generator is short of water or water level is insufficient, the system will automatically replenishment water to avoid dry burning.

● Pre-add water mode -- before adding lye first add a certain amount of water, dilute the digestive tube in the concentrated sulfuric acid, can reduce acid, alkali violent reaction.

● Safety mode - before adding alkali to the sample for proper heating, can prevent acid, alkali strong reaction.
