The PFA impinger is a laboratory container made of perfluoroalkoxy (PFA) resin, primarily used for experimental operations such as gas sampling, liquid collection, and chemical reactions. PFA material offers excellent chemical stability, corrosion resistance, and high-temperature resistance, making it an ideal choice for handling corrosive liquids and high-temperature experiments.

1. Material Characteristics

• Corrosion Resistance: PFA material can withstand strong acids (such as hydrofluoric acid and aqua regia), strong bases, and organic solvents, making it suitable for complex chemical environments.

• High-Temperature Resistance: PFA impingers can operate stably within a temperature range of -200°C to 260°C, making them suitable for high-temperature experiments.

• Low Metal Ion Content: The content of metal elements (such as lead and uranium) in PFA material is extremely low (less than 0.01 ppb), reducing contamination of samples.

• Transparency: PFA impingers are made of transparent material, allowing easy observation of the internal sample state.

2. Main Functions

• Gas Sampling: Used for collecting and analyzing gas samples, such as atmospheric pollutants and industrial exhaust gases.

• Liquid Collection: Suitable for collecting corrosive liquids or high-purity liquid samples.

• Chemical Reactions: Conducts chemical reactions in high-temperature or corrosive environments, ensuring experimental safety and accuracy.

3. Application Fields

• Environmental Monitoring: Used for the collection and analysis of environmental samples such as air and water quality.

• Chemical Experiments: Suitable for handling corrosive liquids like strong acids and bases.

• Semiconductor Industry: Used for ultra-pure liquid transfer and high-temperature corrosive liquid handling.

4. Advantages

• High Cleanliness: PFA material has low contamination, ensuring sample purity.

• Strong Durability: Can withstand multiple uses and harsh experimental conditions, with a long service life.

• Excellent Sealing: Designed with a focus on sealing to prevent gas and liquid leakage.
