Automatic fiber analyzerIt is an analytical instrument that determines the crude fiber content through steps such as acid-base digestion, filtration, and rinsing. The automatic addition of solvents, automatic preheating, and other functions are achieved by using infrared tubes with high thermal efficiency for heating and high-precision immersion and filtration devices to ensure the reliability of experimental results.
Automatic fiber analyzerCharacteristics:
1. Advanced infrared heating methods have heating performance and good control performance.
2. Imported filtration pump, high acid and alkali resistance, good stability, and long service life.
3. The high-precision acid-base washing and filtering device ensures that the sample is not damaged.
4. The preheating of acid alkali distilled water can be controlled separately, and the digestion heating can be controlled separately.
5. All functions such as reagent preheating, addition, sample filtration, and backwashing are designed with electrical automation.
6. Six samples can be processed simultaneously, and the digestion time of the samples can be set.
Automatic fiber analyzerExperimental precautions:
1. The weighing process must be accurate, do not hold the crucible by hand, use a clamp to take it;
When adding liquid to the instrument in the second and subsequent steps, it is necessary to ensure that the liquid is hot to avoid the explosion of the instrument's discharge pipe due to temperature differences;
3. Do not use laundry detergent or cleaning solvents for instrument cleaning. Use hot water for cleaning. If it is indeed difficult to clean, a small amount of solvent can be used for cleaning;
4. After the acid hydrolysis is completed, the drainage should be carried out slowly to prevent floating samples from adhering to the digestion tube wall. If the sample adheres firmly and cannot be cleaned with water, a soft bristled brush can be used to gently brush it off from the bottom;
5. Handle the quartz crucible gently to avoid crushing, bumping, falling, etc;
If the crucible becomes significantly clogged after prolonged use, it can be dried and placed in a furnace at around 500 degrees Celsius for 1-2 hours to burn. After cooling, it can be cleaned again.
