Automatic Sample Injection Fully Automatic Kjeldahl Nitrogen Analyzer

1. Fully automatic injection&distillation&titration system:
The UDK169 fully automatic injection&distillation&titration system is a new product launched by VELP, an Italian company, in 2013 based on its previous product. It inherits many advantages of the previous product and has made changes in some special technologies.
The UDK169 fully automatic injection&distillation&titration system adopts the technology of Italian VELP company: high-efficiency steam generator and innovative titanium condenser (under application), ensuring the high performance and efficiency of the product, and greatly reducing the operating and daily maintenance costs of the instrument. At the same time, it largely meets the needs of continuous operation under experimental conditions, with advantages such as speed, safety, and accuracy, truly achieving unmanned and fully automated protein measurement results.
Main features:
(1) Programmable fully automatic control completes the entire process of automatic sampling and distillation titration, including reagent addition, distillation titration process control, residue emptying, final result calculation, and test result reporting. After selecting the detection program, the test process can be completed with one click, and accurate results can be obtained within a few minutes.
(2) 6-inch ultra large LCD touch screen display, with a simple and complete control panel and operation guidance function, supporting Chinese operation.
(3) Built in 30 international standard testing programs and reserved 24 user-defined programs, convenient and flexible, improving efficiency and good adaptability.
(4) Storage and communication functions, capable of storing up to 100000 sets of data related to experiments, including RS232 and USB interfaces, can be connected to external devices such as analytical scales, computers, printers, keyboards, etc., making it easy to transfer detection data to a PC or perform LIMS format conversion.
(5) Steam generators have advantages such as low maintenance costs, time savings, long service life, and low cost. The titanium condenser optimizes the heat exchange effect and can save a large amount of condensed water.
(6) High safety level: Each unit is equipped with safety protection devices, such as automatic sampler injection, digestion tube position, digestion tube replacement, safety door, reagent level, storage level, cooling water overflow, colorimetric titration, etc.
(7) The UDK169 fully automatic injection&distillation&titration system includes: a fully automatic injection system, a distillation/titration system with built-in chip control, digestion tubes, digestion tube clamps, collection bottles, test tube fittings with sensors, and inlet pipes.
