Characteristics and Applications of PFA Eggplant Bottle
PFA eggplant bottle is a high-purity laboratory container, widely used in trace analysis, acid purification, semiconductor process, chemical experiments and other fields. Compared with traditional glass or quartz materials, PFA eggplant bottle has significant advantages in corrosion resistance, metal ion precipitation, temperature resistance and other aspects.
1. Main characteristics of PFA eggplant bottle
(1) Super strong chemical corrosion resistance
Can withstand strong acids and strong bases (HF, HNO3, HCl, etc.), suitable for acid steam cleaning and trace metal analysis.
Not corroded by organic solvents, suitable for storage and reaction of various high-purity solvents.
(2) Ultra-low metal background, suitable for trace analysis
Metal ion precipitation is extremely low (ppb-ppt level), which will not affect the detection results of precision instruments such as ICP-MS and AAS.
Suitable for ultra-trace analysis (such as semiconductors, pharmaceuticals, and biological analysis) to avoid sample contamination.
(3) High temperature tolerance
Temperature range: -200ºC to 260ºC, can be used for high temperature digestion, acid steam cleaning, microwave digestion and other experiments.
Can be used for high temperature heating and low temperature storage, and will not release impurities due to temperature changes.
(4) High transparency, easy to observe
PFA material is more transparent than traditional FEP, and the sample status can be observed intuitively during the experiment.
(5) Smooth surface, anti-pollution
Not easy to adsorb samples, can be reused after cleaning, suitable for ultra-trace element analysis.
Acid cleaning can be performed to ensure no background contamination.
(6) Strong weather resistance
No aging, not easy to break, more durable than glass eggplant-shaped bottles, especially suitable for long-term storage.
