SKD-180 volatile salt based nitrogen distiller Introduction: Introduction: Volatile base nitrogen (TVB-N) refers to the alkaline nitrogen-containing substances such as ammonia and amines produced by the decomposition of proteins in animal food during the spoilage process due to the action of enzymes and bacteria. This type of substance is volatile, and the higher its content, the more amino acids are destroyed, especially methionine and tyrosine, thus greatly affecting its nutritional value. It is the main indicator reflecting the freshness of raw fish and meat. Features: 1. The shell is made of high-quality ABS engineering plastic, which is resistant to strong acids and alkalis, effectively solving the problem of corrosion resistance and never rusting! 2. The connections of various pipelines inside the instrument are made of specially made rubber hoses that are resistant to high temperature, strong acid and alkali, which improves the accuracy and lifespan of the instrument and does not require replacement for 3 years. 3. The instrument uses corrosion-resistant acid-base valves to add alkali, which reduces the failure rate of the instrument; 4. The instrument tube is equipped with overvoltage protection and steam balance output, effectively eliminating the phenomenon of sample backflow! 5. Using a single-chip computer control, automatic acid addition, automatic distillation, and data storage settings make the measurement object faster, more accurate, and distillation more stable. 6. Cleaning control system, achieving intelligent cleaning of distillers and acid-base circuits,. 7. During the distillation process, automatically compensate for the heating time of the distillation cup.
