DRK-K646 automatic digestion instrument is a fully automatic digestion equipment adhering to the design concept of "reliability, intelligence, and environmental protection", which can automatically complete the digestion process of the Kjeldahl nitrogen experiment. DRK-K646 can be matched with 20-bit or 8-bit digestion instrument according to the sample volume in the laboratory; at the same time, it adopts the Android intelligent operating system, and the host computer is combined with the lifting device and the exhaust gas neutralization device to realize the automation of the entire digestion process.

Main features and advantages ·Fully automated operation, using Android operating system, which can simultaneously control the lifting device and the exhaust gas neutralization device, which effectively improves the efficiency of the experiment and reduces the risk of exhaust gas leakage. ·Standard equipped with lifting device, the digestion tube rack automatically lifts and lowers with the progress of the experiment, reducing the operation of experimental staff and saving cooling time. The use of aluminum deep-hole heating module can improve the heating effect of the digestion instrument and avoid bumping Use ceramics and air ducts for heat insulation, with excellent heat preservation ability, effectively reducing the energy consumption of the digestion instrument Real-time monitoring function, the actual temperature can be displayed in real time and the heating curve can be recorded during the experiment, and the changes in the experiment can be understood and reviewed Built-in storage space of more than 8G, can store unlimited amount of experimental information, and can query historical digestion plan and heating curve at any time Built-in more than 20 recommended solutions, which can be directly called, and more than 500 groups of digestion methods can be customized and stored, which is simple and easy to use The heating rate is controllable, and the fuzzy adaptive PD temperature control algorithm is adopted. While the temperature is accurately controlled, the heating rate can be adjusted according to the experimental situation to adapt to different sample pre-processing Comply with 21 CFR Part11 requirements, can perform authority management and operation log storage With cloud service function, you can upload and download experimental methods and historical data, realize the sharing of methods and permanent backup of historical data It has two data transmission methods, WiFi and USB, to backup and view historical data The whole shell adopts advanced anti-corrosion and wear-resistant Teflon coating, which can withstand high temperature and strong acid corrosionThe characteristics of the digestion and waste disposal system Use PFA sealing cover, long service life, good sealing effect The sealing cover adopts a snap-in design, which is easy to replace Equipped with professional water jet vacuum pump without power supply ·Professional drip tray design to reduce the harm caused by acid liquid pollution and corrosion Characteristics of exhaust gas absorption system The whole machine adopts mould production, with simple and generous appearance In the process of exhaust gas neutralization, two methods of cooling and chemical absorption are used to recover exhaust gas to improve the efficiency of exhaust gas recovery The exhaust gas absorption system can be connected to the host, and the host is uniformly regulated ·Meet the test requirements of more than 10 samples. The use of PTFE corrosion-resistant pipeline design increases the overall life of the instrument Rapid cooling and efficiency improvement The standard automatic lifting device does not require personnel to be on duty. After the experiment is completed, the digestion rack is automatically raised to quickly cool down; at the same time, the instrument has an independent cooling rack, which is flexible and compact, and the sample can be quickly cooled to room temperature. Intelligent control, unattended The digester adopts the Android operating system, the host can synchronously control the lifting device and the exhaust gas neutralization device without separate operation. The lifting and lowering of the digestion pipe and the exhaust gas absorption intensity can be adjusted in real time with the experimental process. Multiple protection, safe and reliable Multiple alarm settings are required. When overvoltage, overcurrent, overheating and failure occur, the instrument will automatically alarm.
