Quartz sub-boiling still is a fully enclosed quartz glass instrument for the preparation of high-purity reagents and high-purity water. It has unique advantages. It has professional technology, novel and beautiful structure, and is easy to install, operate and maintain. Quartz sub-boiling distillation is the use of heat radiation The principle is to keep the liquid phase temperature lower than the boiling point temperature to evaporate and condense to produce high-purity water and high-purity reagents. However, in general quartz stills, due to boiling distillation, water droplets are entrained in the gas, and the gas-liquid separation is not complete, resulting in low water quality; The glass distiller is more polluted by the impurities contained in the glass itself, and the water quality is even worse; the ion-exchange water is also disturbed by organic matter due to the dissolution of organic matter. The quartz sub-boiling distiller not only avoids the pollution of glass impurities, but also because of the liquid The phase temperature is lower than the boiling point, so that water droplets will not be entrained in the steam due to boiling, that is, the gas-liquid separation is complete, so the water quality is extremely high, and no heavy metals are detected by flameless atomic absorption analysis.
SYZ-A and SYZ-550 sub-boiling distillers are produced according to the standards of the Fourth Ministry of Machinery, and after re-improvement and years of practice, they are more professional than similar products: they can use energy reasonably, and use double condensation cycles to extract Pure water, the effect is significantly improved. It has passed the test of Nanjing Metrology and Testing Institute and has issued a test report. The pure water is suitable for polarographic analysis, effective liquid chromatography, ion electrode, atomic absorption analysis, clinical biochemistry, flame photometer and various micro and trace analysis. , it is a desirable equipment for preparing high-purity water or high-purity reagents.
