2. Safety. In the design, safety was fully considered, and passive temperature control was changed to active pressure control.
3 , high digestion efficiency, strong ability, can digest many traditional methods difficult to digest samples.
4. Improve the accuracy and precision of analysis, reduce work intensity and environmental pollution.
5. Shaoxing Shangyu Analytical Instrument Factory can customize various specifications of PTFE high-pressure digestion tanks, and can also customize various specifications of PTFE high-pressure digestion tank liners (tetrafluoro lined cups). To drawing processing.
☆☆ The material of the inner tank of the digestion tank is polytetrafluoroethylene (PTFE for short F4) , its characteristics:
◎ Appearance Pure Baise
◎ High temperature resistance: use temperature -200 ～ + 250 ℃;
◎ Low temperature resistance: -196 ℃ can keep 5%;
◎ Corrosion resistance: resistant to strong acid, strong alkali, aqua regia and various organic solvents;
◎ Insulation resistance: the dielectric performance has nothing to do with temperature and frequency;
◎ High lubrication: the lowest coefficient of friction in solid materials;
◎ No adhesion: No substance is adhered; Strong self-wetting: Friction coefficient in solid materials is 0.04
◎ Non-toxic: it is physiologically inert and can be implanted in the human body; it can be used in the atmosphere for a long time due to aging resistance
◎ Anti-pollution: the blank value of metal elements is low, the content of lead is less than 10-11 g / ml, and the content of uranium is less than 10-12 g / ml;
◎ Anti-leakage: Dropped from a height of 1.2 meters above the ground, the bottle body does not break, the bottle cap does not fall off, and there is no damage or leakage.
Features of high pressure digestion tank
Good corrosion resistance, no harmful substances overflow, reduce pollution, safe to use, and can quickly and losslessly dissolve samples that are difficult to dissolve under normal conditions and samples containing volatile elements after heating and boosting. Beautiful appearance, reasonable structure, simple operation, shorten analysis time and reliable data. It has a Teflon bushing inside, double-layer care, and is resistant to acid and alkali. It can replace the platinum crucible to solve the sample dissolving problem of analyzing trace elements in high-purity alumina.
High-pressure digestion tank operation method
The reactant refers to the inside of the kettle, and the feeding coefficient is guaranteed to be less than 0.8. When the reactant is corrosive, it should be placed in a tetrafluoro liner to ensure that the kettle body is not corroded. The HZ hydrothermal synthesis reactor is placed in the heater, and the temperature is raised to the required reaction temperature (less than the specified safe use temperature) according to the specified heating rate. When the reaction is cooled down after the reaction is completed, it is also necessary to operate strictly in accordance with the prescribed cooling rate to facilitate safety and service life of the reaction kettle. After confirming that the intra-abdominal temperature is lower than the boiling point of the solvents of the reactant system, the kettle lid can be opened for subsequent operations. After each use of the hydrothermal synthesis reactor, it should be cleaned in time to avoid rust. Care should be taken in the sealing of the kettle body and kettle cover line to prevent damage to the kettle.
